As the economy develops and the population increases, there is an increasing demand for goods such as timber, food, medicine, and so on, and ecological services such as fresh water and the environment. Because goods and services produced by the original forest cannot meet the increasing need of people, so most of the original forest has become farm...

Since 1995, the yield, benefits, and plantation area of red plum apricot have increased dramatically. But as red plum apricot trees’ canopy and roots grew, soil drying appeared and sometimes become severe in a wet year. The severe soil drying influence the yield, quality and benefits of red plum apricot because precipitation is small and with a big...

Along with economic development and an increase in population, there is an increasing demand for goods such as timber, food, medicine, and so on, and ecological services such as fresh water and the environment. Because goods and service produced by the original forest cannot meet the increasing need of people, so most of the original forest has bec...

It is estimated that around 62% of the geographical location of Sindh is arid, including Thar Kohistan and Nara, along with a large area of the coastal belt (350km) and rural areas. Prevailing droughts in arid and semi-arid regions of Sindh are increasing day by day. After using a huge amount of water from the Indus river, a small amount of water w...

Purpose: It is important for sustainable use of soil water resources to forecast soil moisture in forestland of water-limited regions. There are some soil moisture models. However, there is not a better method to forecast soil moisture. Methods: The change of soil moisture with time were investigated and the data of soil moisture were divided into...

Non‐native plantations can effectively conserve soil and water and improve the ecological environment, but soil desiccation can occur and may become severe in forest and grass lands in water‐limited regions, leading to soil degradation, vegetation decline, and crop failure.Therefore, it is necessary to regulate the changing relationship between pla...

The goods and services produced by forest and vegetation ecology system is the power by which human society can be promoted fast in high-quality and sustainable way. With the increase of population and economic development in water-limited regions, there is an increasing demand for the quantity and variety of forest vegetation ecosystem products an...

The maximum infiltration depth and soil water supply must be evaluated in order to estimate the soil water resource use limit by plants and soil water carrying capacity for vegetation, and realize the sustainable use of soil water resources. However, there is no non-destructive method to estimate maximum infiltration depth and soil water supply. We...

Non-native plantation can effectively conserve soil and water and improve ecological environment, but soil desiccation occurs and then changes to severe desiccation in most forest and grass lands of water-limited regions, which causes soil degradation, vegetation decline and crop failure, so it is necessary to regulate the changed relationship betw...

Red plum apricot is the best apricot over the world. Since having been introduced into Guyuan county in 1987 from Shaanxi province, red plum apricot grows well and then has been selected as good varieties to popularize in semirid loess hilly regions because the color of red plum apricot is beautiful, aroma fragrant , and taste is the mix of sour an...

Rice is a main food over the world. With the growing population and urbanization, the demand for the rice is increasing.To ensure the sustainable produce and market supply of rice is most important to meet the people’s need of rice and the sustainable development. Most of distribution area of rice is in resources-limited regions, and sometime natur...

The instantaneous solar radiation flux density incident on the horizontal surface near the ground, consisted of three sections, direct radiation, scattered radiation, and thermal radiation flowing down through the atmosphere, directly or indirectly comes from the sun. The dynamics of the solar radiation flux density incident on the horizontal surfa...

Impact of Initial Planting Density on Soil Water Resource use Limit by Plants Soil Water Resource Use Limit by Plants (SWRULP) is one of the most important indexes to express whether or not plant overuses soil water resources. However, it is still unclear how the impact of initial planting density on SWRULP. In this study, we investigated the chan...

Understanding the vertical distribution dynamics of soil moisture is essential for estimating soil water resources, controlling soil degradation and regulating the relationship between soil water and plant growth in water-limited regions. There have been a few studies of the vertical change of soil moisture in forestlands, but there are few models...

On the Loess Plateau of China, deep rooted, fast-growing species, such as caragana (Caragana korshinskii Kom.), are widely used in afforestation projects. High planting densities and soil water consumption has led to soil desiccation and degradation. We conducted a two-year (2002 to 2003) field experiment assessing the effect of caragana planting d...

Height growth of Caragana korshinskii in semi-arid loess hilly region was not always monotonous increasing with time. Because growth power was less than growth resistance in late growth stage, plant height weakly reduced with time. In this article, two growth model were established. Adding a growth resistance factor to the classical Logistic model,...

In order to develop a method to estimate soil water infiltration depth and the soil water supply, an experiment on soil water infiltration in situ in artificial Caragana forest was conducted at the Shanghuang Eco-experimental Station in the semiarid Loess plateau of China. The results showed that the soil water infiltration depth is equal to the di...

Taking Caragana korshinskii as test object, and by using neutron probe, a long term observation was conducted on the soil water and plant growth during the process of vegetation restoration in semi-arid loess hilly area. The results showed that after seeding on waste land, the capability of plant community in conserving soil and water was promoted...

Determining initiation stage to regulate the plant growth and soil water is the base of sustainable use of soil water resources. In this paper, the dynamics of soil water were continuously measured with a neutron probe in fixed positions in the wasteland and newly sowing Caragana forest land during the period from 2002 to 2006 and the data measured...

Vegetation carrying capacity of soil water is the base for regulating the density and controlling productivity of a community in Which soil deterioration appeared in the form of excessive soil drying under perennial grass and forest，It is important to conduct research on vegetation carrying capacity of soil water for forest management. In this pape...

under perennial grasses and forests. Excessively dry soil influences the grow th and development, stabilization, econom ic and ecological benefits of plant communities, which is one of the most important problem s of vegetation rehabilitation. In this paper, the authors analyzed the relationship between soil desiccation and drying of the root zone...
