摘要:
随着城市化和国民经济的高速发展,河流生态功能受到严重威胁.为评价城市建成区河流的生态功能现状,为后续生态修复与海绵城市规划提供理论依据,以深圳市大沙河为例,采用以水生生物为核心的指标评价法对水文、水质、生境和生物多样性维持4项功能的10个指标、14个指数进行具体评价,并通过层次分析法计算权重,构建河段尺度下的河流生态功能评价指标体系,对大沙河生态功能进行评价.结果表明,大沙河中游受人类活动干扰较小,具有较健全的生态功能,为Ⅱ级河段;上游和中上游区域为Ⅲ级,部分生态功能受到威胁;下游河口段为Ⅳ级河段,受人为影响严重.结合生态功能评价结果,对各河段提出了针对性的生态修复策略,并从污染物、生物物种管理、生态系统的调控及市民的科普教育等多个维度提出了河流生态系统管理措施.研究结果可为城市建成区河流的生态功能评价与生态修复及海绵城市建设提供依据与参考.
Abstract:
With the rapid development of urbanization and national economy, the ecological function of rivers has been seriously threatened. In order to evaluate the present situation of ecological function of rivers in urban built-up areas and provide theoretical basis for subsequent river ecological restoration and sponge city planning, we carry out a case study of the Dasha River in Shenzhen city. We construct the ecological function evaluation index system at the reach scale for the Dasha River, in which 10 indicators and 14 indexes of four functions of hydrological support, water environment sustainment, habitat and biodiversity maintenance are evaluated by index evaluation method with aquatic organisms as the core. The index weight is calculated by the analytic hierarchy process method. The results show that the middle reach of the Dasha River is in class Ⅱ level, which is less disturbed by human activities and has relatively integral ecological functions. The upper and middle upper reaches are class Ⅲ areas and some ecological functions are threatened. The lower estuary section is class Ⅳ reach, which is seriously affected by human activities. Combing with the evaluation results of ecological function, we put forward the ecological restoration strategies for each reach, and suggest the daily management measures from the aspects of pollutant, biological species management, ecosystem regulation, and public education. This study provides basis and guidance for the evaluation and restoration of the ecological function and the sponge city construction in urban built-up areas.
