Construction of Health Evaluation System for Aquatic Ecosystem of Typical Lakes in the Plain River Network Area of Northern Zhejiang
In response to the lack of different evaluation standards for aquatic ecosystems characterized by different current habitats,this paper selected the plains river network area in northern Zhejiang as the study area.Based on the functional structure and regional characteristics of typical lake aquatic ecosystems in the plains river network,a theoretical framework for evaluating the health of aquatic ecosystems was proposed,which covered four major elements,namely,the health of physical habitats,water quality,sediments,and aquatic biomes,and involved 13 evaluation indices.Following the principle of"taking the current standards and norms as the first,taking the existing research results as the reference",the scoring standard of each index was clarified.The comprehensive evaluation method was used to determine the aquatic ecological health evaluation level of lakes,and a set of scientific and applicable aquatic ecological health evaluation system of typical lakes was constructed,in order to provide theoretical support for the evaluation and management of the aquatic ecosystem health of typical lakes in the plains river network in northern part of Zhejiang Province.
