Regional Risk Assessment

Regional ecological risk assessment (RERA) can be defined as a risk assessment deals at a spatial that contains multiple habitats with multiple sources of multiple stressors affecting multiple endpoints and the characteristics of the landscape affect the risk estimate. Therefore, establishment RERA index system was quite complicate and being a hotspot in resent research. This paper discussed the history of RERA, reviewing RERA study in China and the proper site selection in Hulunbeier presenting RERA index system. An index system was set up based on the principle: Comparability, Available and Relevant. This index system developed by regarding the risk of land use change, industrial pollution and social economy as well as adopted ecosystem services, landscape and support system for regional risk assessment of degraded land (SYRIADE) methods.

Index Method

Plateau lakes have significant ecological value. With economic development, lake pollution and ecological degradation have become increasingly prominent. There are many ecological risk assessment methods. This article combines four different ecological risk assessment methods including single-factor pollution index, geological accumulation index method, potential risk index method, and pollution load index method to analyze the heavy metal pollution in Yangzong seabed mud as comprehensively as possible. It shows that the results obtained by different ecological risk assessment methods are slightly different. The overall trends of the geological pollution index and the single-factor pollution index are similar. In terms of time, except for the two elements of mercury and cadmium, the contents of other heavy metals in 2019 are lower than in 2018, indicating that heavy metal pollution has decreased in 2019; from the perspective of spatial distribution, In 2018, the overall pollution level on the south side of Yangzonghai was higher than that in the central and northern regions of Yangzonghai . On the whole, whether it is the potential risk index or the appropriate pollution load index, the pollution level on the south side of Yangzonghai is higher than that in the central and northern areas of Yangzonghai, and the northern area has the least pollution.
