A Comprehensive Indicator Representing Process:Water Environment Sustainability Index for downstream marsh
Several issues impact environment sustainability, its evaluation index usually contains so high number of indicators and parameters that it is constrained in data-scarce regions where lack of consistent time series data especially.So, the assessment would just be carried on present situation, rarely on process.A water environment sustainability index for downstream marsh representing process was developed and proposed in this paper.Applied to Zhalong Wetland, the WESI scores the highest (3.47) at 1988 to the lowest (1.92) at 2005 that could be divided into 3 periods: 1980s (good level), 1990s (bad level) and 2000s (rising up slowly under human manipulation).To maintain it at a good level, it is necessary to drain water from Nenjiang River year by year.
