... If two or more ecosystem services simultaneously increase or decrease in response to the same driver, there will be a synergistic effect. For example, increasing water regulation in coastal wetlands could also enhance species diversity (Tockner et al., 1999;Wang et al., 2019) because there is a synergistic relationship between carbon storage and biodiversity support (Yang et al., 2018). If the policy maker simply quantifies the offsetting required for each individual impact and adds these together, the end result may be overcompensation, coupled with an insufficient area being made available for restoration offset. ...
... The mean annual river discharge is 10,524 m 3 s −1 and varies seasonally reaching a peak of 22,200 m 3 s −1 in summer and about 3,988 m 3 s −1 in winter (Li et al., 2006). About 80% of the total flow occurs in the wet season from April to September, with 20% in the dry season from October to March (Fan, Cui, Zhang, Zhang, & Zhao, 2012). The tidal cycle in this region is a mixed, dominantly semi-diurnal tidal regime with daily inequality in both range and time (Jiang, 2007;Zhang, Ruan, Zheng, Zhu, & Wu, 2010). ...
... Rong et al. studied the contamination of heavy metals in water and soil from College Town in the Pearl River Delta. The concentration of some heavy metals, such as Cu, in their study was very low in comparison with the soil around Sarcheshmeh Cu mine (47). ...
... Generally, water quality management is performed using different water quality models of water channels and rivers, the point and nonpoint sources playing a vital role in the nitrogen dynamics, biochemical oxygen demand (BOD), and dissolved oxygen (DO) [7][8][9][10]. The surface Water 2022, 14, 1058 2 of 13 water quality modelling can be an effective means for the simulating and predicting of contaminants fate and transport in the sustainable water environment [11,12], which can significantly save an enormous amount of labour cost, material, time, and laboratory experiments. Furthermore, it is unreachable for the in-situ sampling and experiments in some situations due to weather, hazardous, or unusual ecological issues. ...
... However, few studies have investigated the regulate factors of litter decomposition and the characteristics of nutrient release such as carbon, nitrogen and phosphorus under different ground water conditions. The decomposition process of plant litter is subject to many internal factors such as plant community type, physical and chemical quality characteristics of the litter itself (Chimney and Pietro 2006;Yan Baoshan and Zheyuan 2012), and external factors such as water status (Langhans and Tockner 2006;Peltoniemi et al. 2012), temperature status, microbial status (Ferreira and Chauvet 2011) and the influence of environmental conditions such as nutrient supply and availability of exogenous nutrient sources in wetland ecosystems (Rejm ankov a and Houdkov a 2006). A large number of studies have shown that hydrological processes (such as groundwater level, depth, duration and frequency of flooding) are the main factors affecting the decomposition of litter (Day 1983;Valk et al. 1991;Neckles and Neill 1994;Langhans and Tockner 2006;Hou et al. 2012;Peltoniemi et al. 2012;Alexandra et al. 2013;Wu et al. 2017). ...
... On one hand, the detailed model ADM1 [1], with 26 state variables, is a gold standard for analyzing and simulating the process, but it is seldomly applied for developing state estimators due to its complexity and the amount of measurement required. For instance, [2] designs a robust interval observer to estimate 14 state variables using 10 measured variables, e.g., substrate concentrations and measurements related to biogas. On the other hand, low-order models, considering simple one-, two-or three-step reaction systems, such as the AMOCO (or AM2) [3], are often considered for the development of observers and controllers [4][5][6][7][8]. ...
... However, recent global economic and industrial development has resulted in an increase of nutrients and heavy metal accumulation in freshwater bodies through industrial discharge, biological waste decomposition, and agricultural run-off. This has led to the deterioration of macrophytes diversity and populations in these environments (Zhang et al., 2012). Ammonium is a major source of nitrogen in fresh waters. ...
... ex Steud., is a broadly distributed wetland grass species (Poaceae) characterized as a perennial with extensive rhizomes that can rapidly proliferate in suitable areas. This plant can survive in both fresh and saltwater ecosystems, tolerating salinities up to 28 parts per thousand (ppt) (Bai et al., 2012). Due to its high intraspecies diversity, phenotypic plasticity and ability to build up biomass, P. australis is often the predominant species in the ecosystems it inhabits (Packer et al., 2017). ...
... Notably, NH 4 + -N contents in the soil and effluent stood at a high level. The accumulation of NH 4 + -N in the soil could be contributed to the conversion of NO 3 − to NH 4 + via NO 2 − -N (DNRA) under the anaerobic environment (Sgouridis et al., 2011;Liu et al., 2017) and mineralization of organic N because of anaerobic nutrient cycling promoted by the flooding conditions (Tete et al., 2015;Jia et al., 2017;Gao et al., 2012). Moreover, the consumption of NH 4 + -N by nitrifying microorganisms might be inhibited (Szukics et al., 2010) while its consumption by denitrifying microorganisms might be enhanced (Gómez et al., 2002). ...
... In context, Rietz and Haynes (2003) reported that organic matter decomposition was inhibited by increasing salinity which might cause a substantial decline in potentially available N, while Xie et al. (2020) observed that the total microbial biomass of marsh soils was adversely affected by soil salinity. Furthermore, Bai et al. (2012) reported that the amount of available N generally showed a negative relationship with soil salinity. ...
