摘要
文章针对不同现状生境特征水生态系统缺乏差异性评价标准的需求,选取浙江北部平原河网地区作为研究区域,基于平原河网中的典型湖漾水生态系统功能结构、区域特征,提出其水生态健康评价理论框架,涵盖物理生境健康、水质健康、沉积物健康和水生生物群落健康4大要素,涉及13项评价指标。遵循“以现行标准规范为先、以现有研究成果为鉴”的原则,明确每项指标的评分标准,采用综合评价法确定湖漾水生态健康评价等级,构建了一套科学适用的典型湖漾水生态健康评价体系,以期为浙北地区平原河网中典型湖漾的水生态系统健康评价与管理提供理论支撑。
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.
