Development of a Structural and Functional Approach in Assessing Ecological Integrity of Songhua River, China
The concept of ecological integrity has been increasingly used to guide the decisions for water environment management in China. It requires an accessible and effective approach of measuring ecological integrity. However, previous researches focused on structural indicators of ecosystem, with ignoring the interaction between structural and functional components. In our work in Songhua River (Northeast China), we attempted to develop an index of ecological integrity with consideration of both structural and functional indicators. The survey was conducted twice (June and September, 2015) at 40 sites on the mainstream and tributaries of Songhua River. Benthic invertebrates were sampled with a standardized level of effort with artificial substrate, and water chemistry and habitat data were collected at the same time. Of 35 potential metrics considered, 6 core metrics were finally chosen: EPT%, Invertebrate Richness, MCI (Macroinvertebrate Community Index), Nitrates and nitrites, Land use and Gross primary productivity. According to the results, the least-impacted sites had significantly higher mean scores than the other site classifications. As for its practical applications, it can be used to improve ecological integrity monitoring programs by contributing to the selection of meaningful indicators.
