    ABSTRACT: With the aid of canonical correlation analysis, the relations among soil nutrients, soil microorganisms, and soil enzyme activities were studied in vegetation restoration areas of degraded and eroded soils in the Nverzhai watershed in northwestern Hunan. The main results were as follows: the key factors in soil nutrients, microorganisms, and enzyme activities were N and P elements, number of bacteria, carbon and nitrogen in soil microbial biomass and the activities of urease, polyphenol oxidase, phosphatase, and invertase. The activities of urease and polyphenol oxidase are related to the inversion of N and P elements that had important impact on the accumulation of carbon and nitrogen in soil microbial biomass. Moreover, the activities of urease, polyphenol oxidase, and phosphatase could promote carbon accumulation in microbial biomass; however, invertase activities inhibited the accumulation of microbial biomass nitrogen. On the other hand, urease activities were beneficial to the N element content in soils but unfavorable for P elements. There is a negative relation between polyphenol oxidase activity and N element content. For every canonical variable group, the tendencies of soil nutrients, microorganisms, and enzyme activities to accumulate in different soil layers in different vegetation restoration communities could offer some scientific basis for the diagnosis of the health of the soil and the site type division in the process of vegetation restoration.

    ABSTRACT: AFLP fingerprinting analysis of Fusarium circinatum, Nirenberg and O’Donnell and relative species was carried out. Ten primer-pairs that could generate abundant polymorphism fragments were screened. A total of 298 nucleotide acid fragments were amplified with the primers from the template of the 17 strains of Fusarium spp., among which 283 fragments were polymorphic. Percentage of polymorphic loci produced by each pair of AFLP primer-pair was 94.97% in average and varied from 89.29% to 100%. All these data indicated that considerable genetic variation existed among F. circinatum and relative species at DNA level. Molecular genetic distances among Fusarium spp. were calculated, and the relationship among them was described quantitatively. Compared with biological species, the result of cluster analysis was basically similar to the phenotypic classification of species. Genetic diversity of E-AT/M-CAA AFLP fingerprinting of Fusarium spp. was analyzed, and specific and difference bands for each species and all Fusarium section Liseola tested were identified based on the E-AT/M-CAA AFLP fingerprinting.

    ABSTRACT: Using electronic microscopy, ultrastructural changes were observed during differentiation in a secondary xylem vessel element (VE) in Populus deltoides. Results showed that morphological development of VE differentiation was successively divided into three stages. First was primary cell wall outspread (the initial stage), where the VE was highly vacuolated and the protoplasma distributed along the cell wall. Second was secondary cell wall construction (the pivotal stage), where substances accumulated before the tonoplast broke, and the VE organelle was distinct. Golgi bodies and vesicles, which were associated closely with synthesis and transportation of secondary cell wall substances, were also abundant. After the tonoplast broke, these substances accumulated faster. Simultaneously, the protoplasm was disaggregated and the agglomerated chromatin was distributed over the margin of the nucleus, showing the typical characteristics of programmed cell death (PCD). During secondary cell wall formation, no cell wall substances accumulated between the terminal cell walls of neighboring VEs. In addition, terminal cell wall substances were disaggregated in the post secondary cell wall formation. Later, when the remnant terminal cell wall was broken in the third stage, perforation occurred. Thus, for these successive stages of VE differentiation, the critical stage, when differentiation was not reversible, was at the start of secondary cell wall formation with succeeding VE differentiation similar to a typical PCD process.

    ABSTRACT: In order to improve the accuracy and reliability of identifying wood defects and to realize the maximum wood utilization of trees, we employed an experimental method to test the stress wave propagation velocity in standing Fraxinus mandshurica trees selected from the Harbin Forest Experimental Station in winter. Thirty standing trees in good conditions were taken as test specimens and stress wave propagation velocities were measured using a FAKOPP Microsecond Timer in trees in both fall and winter. The test data were processed with the aid of Excel and SPSS software. The results show that 1) the velocities in longitudinal and radial stress wave propagation in frozen F. mandshurica trees were much higher than those in the non-frozen trees; 2) there was a highly positive correlation between longitudinal stress wave propagation velocity in frozen and non-frozen states, with a correlation coefficient of 0.82, as well as a positive correlation between radial stress wave propagation velocity in frozen and non-frozen states with a correlation coefficient of 0.87; 3) in the frozen state, the longitudinal stress wave propagation velocity was significantly affected by the moisture content (MC) of standing tree, while it was not obvious in the non-frozen state and 4) the radial stress wave propagation velocity was not significantly affected by MC in either frozen or non-frozen state.

    ABSTRACT: Leaf litter decomposition of Castanopsis fissa, Cinnamomum camphora, Michelia macclurei and Mytilaria laosensis in mixed broad-leaved plantation and pine plantation was studied by the litterbag method for 1 year. Leaf litter decomposition rates of the four species were highest in Cinnamomum camphora, followed by Mytilaria laosensis, Michelia macclurei, and Castanopsis fissa. The decomposition rates of all four species were higher in the mixed than in pine plantation. The decomposition processes of all species followed Olson’s exponential model. The decomposition coefficients (k) of all species were also higher in the mixed plantation and had the same order as the decomposition rates. The nitrogen contents of leaf litter of the different species studied increased initially and then decreased with time. Net release of N only occurred in pine plantation. Potassium contents appeared to decrease first but later increase, and net release was only found in mixed plantation. Calcium, magnesium and boron all showed similar pattern of initial increase followed by later decrease. They all had net release in both mixed and pine plantations. The release of phosphorus varied greatly between species and showed no clear trend.

    ABSTRACT: Floristic composition of the evergreen broad-leaved forest in Jiulianshan Mountain was analyzed based on field investigations and community ecology. The community is rich in species diversity, with 144 spermatophyte families including 379 genera and 647 species, in which there are 6 gymnosperm families including 8 genera and 9 species, 21 monocotyledon families including 77 genera and 116 species, and 117 dicotyledon families including 294 genera and 522 species. Dominant families of the flora are Fagaceae, Lauraceae, Aquifoliaceae, Rosaceae, Ternstroemiaceae, Theaceae, Rubiaceae, Moraceae and Euphoarbiaceae, most of which are of tropical & subtropical distribution. As for family systematic distribution, the ratio of tropical & subtropical to temperate genera is 100:62.8 in 142 genera of 16 families. As for generic distribution in field investigation data, the tropical & subtropical areal type accounts for the majority of genera, in which there are 205 genera belonging to the tropical & subtropical areal type, 131 genera belonging to the temperate areal type, 35 genera belonging to the cosmopolitan areal type and 8 genera belonging to the endemic-to-China areal type. The ratio of the tropical & subtropical to temperate genera was 100:63.9. Floristic composition of the evergreen forest community in Jiulianshan and the typical species of the zonal flora will provide a scientific foundation for stand rehabilitation and stand establishment approximating a natural evergreen broad-leaved forest community. This study also indicates that the sample data based on community research are valid and convenient for floristic and environmental analysis of the evergreen broad-leaved forest community from the Jiulianshan Mountain.

    ABSTRACT: The structure, distribution and patterns of resin ducts in processes of its initiation and development were studied with the methods of thin section and ultrathin section. This paper emphasized the ultrastructural changes during canal development by a ring of the live epithelial cells, and the epithelial cells were usually surrounded with one or two layered sheath cells, which were normal parenchyma cells in some primary resin ducts and became dead cells with thick walls in other primary and secondary resin ducts. The resin ducts were found to occur in almost all organs, except in cotyledon. The resin ducts were formed by schizogeny and their development can be divided into three stages (e.g., initial stage, formation stage and mature stage). At the initial stage, the initial cells had many plastids without integral membrane structures, which contain one or two starch grains in them, and there are a few black osmiophilic droplets on the endoplasmic reticulum and membranes. A small number of osmiophilic droplets were present in the plastids. At the formation stage, the number of plastids, mitochondria and Golgi bodies in epithelial cells increased. The plastids were commonly surrounded by endoplasmic reticulum sheath. The larger osmiophilic droplets in cytoplasm and the smaller osmiophilic droplets on the plastids envelope, mitochondrion envelope and Golgi vesicles obviously increased in number during canal developing. At the mature stage, the cytoplasm of epithelial cells became thin with small nucleus. The number of mitochondria and Golgi body decreased, but numerous plastids still existed. Osmiophilic droplets were abundant in epithelial cells as in previous status. Taken together, the structures of plastids in epithelial cells gradually became well developed and the synthesis of resin was remarkably enhanced during resin duct formation and plastids should be the main site for resin synthesis.

    ABSTRACT: In this paper, the growth rate of five wood-rotting fungi, i.e., Coriolus versicolor, Irpex lacteus, Fomes fomentarius, Piptoporus betulinus and Pholiota adiposa, in solid medium and their biomass in liquid culture medium were compared by measuring mycelium length and dry mass. The activity of three main ligninolytic enzymes in those fungi, namely LiP, MnP and Lac, were also tested by colorimetry. At the same time, these fungi were used to decay the wood samples from 300 natural trees of white birch, to study their wood-decaying ability by measuring wood mass loss. The result showed that the growth rate, biomass, ligninolytic enzyme activity, and wood-decaying ability of the fungi were incompletely correlated. The growth rates of C. versicolor and I. lacteus were faster than those of P. betulinus and F. fomentarius; P. adiposa was the slowest in growth. The biomass of P. betulinus was the highest; C. versicolor, I. lacteus and F. fomentarius were in the middle, and P. adiposa was the lowest. There existed LiP, MnP and Lac activities in all fungi except P. betulinus, and the enzyme activities induced by wood powder were all higher than those of the control. The Lac of I. lacteus and the LiP of F. fomentarius and P. adiposa were only expressed in wood powder medium; the longer the fungi were cultured, the higher activity the enzyme had. The decomposition ability of C. versicolor to wood samples was the highest, followed by F. fomentarius and P. betulinus; I. lacteus and P. adiposa were the lowest.

    ABSTRACT: Due to the embarrassment that may occur from trying to define the forest in the present situation, this paper gives a new approach through the functional analysis of the forest rather than a simple physical description. Here, the forest is now actually the result of natural and social work. The forest has provided the environment, the economic resources and the infrastructure, respectively, and for now, the forest appears as a structured body and takes responsibility in modern human society. With its characteristics of varied hierarchical structure, limited functions, an open system, a dynamic system, moderate mould ability, varied stable equilibrium, etc., it is suggested that the related matching policy on forests should be updated as follows: to define the forest in its entirety, to specialize the public management, to diversify the management objectives, and to cultivate the forest as a continuous procedure. From the experiences of developed countries, we establish a new state-owned forest system.

    ABSTRACT: Forestry division has been discussed rarely since 1995 in China. The growing interest in forestry provides an opportunity to improve the research tools and approaches that can help achieve a broader understanding of forestry division. Based on research in Yong’an, Fujian Province of China, a framework that may be useful in correlative forestry division study was proposed: 1) the factor-system for Yong’an forestry division was established; 2) the factors were extracted with spatial analysis; 3) the forestry division method of integrated modeling at county level based on GIS was processed. The method was taken through principal components analysis, building the comprehensive model, discriminate analysis, seeking the ideal number of divisions and eliminating the fine polygons. The outcome showed that the method based on GIS with comprehensive modeling could reflect the present situation of forestry development. The relative dominant subdivisions were distinguished reasonably, and a specific direction in forestry development is presented. According to the statistics of the subdivisions’ state, the relative dominant subdivisions were clearly demonstrated.

    ABSTRACT: By modeling the condition of light climate, we studied the negative effect of shadows in a shelterbelt forest. Based on the calculation of the apparent trajectory of solar motion according to an ellipsoid crown projection model and a Monsi light transmission model, radiation values of 36 experimental sites were measured using a light quantum meter. Estimates of daily solar radiation distribution from measured values were obtained. We built a crown projection model and simulated the conditions of a light climate in the forest. The trajectory of the shadow motion is shaped like a butterfly arc. The situation of the outside is affected by tree height (H) and that of the inner arc by height below the branches. In an area of 1.0 × H (toward the east and west of the tree) and 0.6 × H (toward the north), transmittance was below 90%, which means that the effect of shadow hazards occurs in this area. As well, the effect was strong at the bottom of the tree. The area of shadow hazards in the east and west of the tree was large and small in the south. The projection area of the shelterbelt forest was largest along an east and west direction. A certain distance between crops and the shelterbelt should be maintained when the shelterbelt is in a north-south direction. Therefore, the effect of shadow hazard will decrease north of the tropic of cancer. Cutting out the lower branches from the trees of the existing shelterbelt in a suitable and timely manner can reduce the area of the shadows.

    ABSTRACT: I analyzed and elaborated the trends in and responses to global change in arid regions of China, from the perspective of nine variables, i.e., temperature, precipitation, river runoff, melting glaciers, water level of lakes, wind power and evaporation, vegetation, oases, and desertification. The climate and hydrology data I cited represent many years of observations. I conclude that, since the 1980s, the climate in arid regions of China has clearly changed with rising temperatures and precipitation in most areas. Wind power and the number of galestorm days have continuously decreased, which resulted in an improvement of humid conditions and increases in river discharge and water levels of lakes. Simultaneously, vegetation also has improved and the process of desertification has essentially been arrested. Although there are some unfavorable developments, such as decreased river flows or flow interruptions and downstream oases have suffered from degradation, these incidental cases should not distract our attention from the generally favorable trends during the middle and late 20th century. These discordant phenomena are not consequences of climate change but rather of unsuitable human activities. Despite a substantial increase in precipitation, the level of the original precipitation was so small that any increase in precipitation was still small. As a result, none of the fundamental conditions such as a scarcity of water resources and precipitation nor the landscape of drought-ridden deserts in the arid regions will change. The vulnerability of the eco-environmental system in the arid regions will not change fundamentally either in the near future.
