Zhangjiangkou Mangrove National Nature Reserve is a subtropical wetland ecosystem in southeast coast of China, which is of dense population and rapid development. The concentrations, sources, and pollution assessment of trace metals (Cu, Cd, Pb, Cr, Zn, As, and Hg) in surface sediment from 29 sites and the biota specimen were investigated for better ecological risk assessment and environmental management. The ranges of trace metals in mg/kg sediment were as follows: Cu (10.79–26.66), Cd (0.03–0.19), Pb (36.71–59.86), Cr (9.67–134.51), Zn (119.69–157.84), As (15.65–31.60), and Hg (0.00–0.08). The sequences of the bioaccumulation of studied metals are Zn > Cu > As > Cr > Pb > Cd > Hg with few exceptions. Cluster analysis and principal component analysis revealed that the trace metals in the studied area mainly derived from anthropogenic activities, such as industrial effluents, agricultural waste, and domestic sewage. Pollution load index and geoaccumulation index were calculated for trace metals in surface sediments, which indicated unpolluted status in general except Pb, Cr, and As.

One of the world natural heritage Three Parallel Rivers core region Yunnan Baima snow mountain national nature reserve as the study area, on the basis of full consideration natural and social factors of reserve, we have established the ecology risk evaluation index system and model in the study area, and has put forward type alpine canyon regional ecological risk assessment of the theory and technical route. We have evaluated risk of the area, and obtained distribution of the risk degrees, and replenished alpine canyon type area demonstration for regional ecological risk assessment. Based on the ecological risk assessment, we put forward the ecological planning in the study area.

National Nature Reserve

Hengshui Lake National Nature Reserve is one of the most ecologically valuable freshwater wetlands in the northern plains of China. It provides crucial staging and wintering habitats for a large variety of endangered waterbirds. However, this unique wetland has suffered from serious habitat fragmentation and ecological function degradation caused by increased socioeconomic activities within and surrounding the Nature Reserve. With the aim of enhancing the Reserves ecological function while balancing conservation priorities and indispensable socioeconomic activities, the ecological risks resulting from each three scenario were evaluated. To conduct this research, we developed a systematic framework for ecological risk assessment, in which indices of biodiversity, ecological vulnerability and ecological risk were introduced and employed. Then, an ecological risk assessment was conducted for the scenarios and the pros and cons of each scenario were evaluated based on the applicability of a particular risk in each situation. The results of modeling and assessments provided the basis for adopting wetland restoration scenarios allowing for the development of practical suggestions for wetland restoration and habitat modification.
