摘要
生物多样性评价是生物多样性保护与管理的基础.本研究基于压力-状态-响应(PSR)模型框架,构建了 14 个流域尺度指标以及 23 个生态系统尺度指标的巢湖流域生物多样性评价指标体系.该指标体系可全面反映生物多样性状态、变化、威胁和决策等综合因素的影响,为评估巢湖流域等长江中下游地区山水林田湖草系统保护修复成效、优化生物多样性保护策略提供指导.评价结果显示:2022年巢湖流域水环境一级保护区内湖泊、湿地生态系统的生物多样性水平均处于较高级别,系统反映了近10年巢湖的综合治理成效.
Abstract
Biodiversity assessment is the basis for biodiversity conservation and management.Based on the"Pressure-State-Response"(PSR)model,this study developed a catchment-scale(14 indicators)and ecosystem-scale(23 indicators)biodiversity evaluation indicators system for Chaohu lake catchment.The impacts of state,change,threats,policy decision of biodiversity can be well reflected in this indicators system,and thus provides technical support for evaluating the effectiveness of the integrated protection and restoration of mountain,water,forest,farmland,lake and grassland in the middle and lower reaches of Yangtze river,and optimizing biodiversity conservation strategies.Additionally,it was found that the biodiversity levels of the lake and wetland ecosystems in the first-class water environment protection zone in the Chaohu lake catchment were comparatively high in 2022,indicating the effectiveness of the integrated treatment of Chaohu lake in the past decade.
