摘要:

湿地健康是反映湿地生态系统整体状态的重要指标,是湿地恢复和科学管理的重要依据。以青海西宁湟水国家湿地公园为研究对象,构建了以生态环境、服务功能和社会环境组成的综合健康评价体系共20项评价指标,评价湿地恢复工程实施5年后的健康状态。通过野外调查、实验分析和问卷调查等方法获取基本数据,基于层次分析法(AHP)和专家咨询法确定各指标权重,通过健康综合指数(Comprehensive Health Index,CHI)对湿地健康状况进行分级评价,并运用指标的净变化值(Net Variation Value,NVV)分析湿地恢复效果的分类评价。结果显示:青海西宁湟水国家湿地公园湿地的健康综合指数由2013年的0.45(一般)上升到2018年的0.73(良好);湿地恢复效果存在空间差异,公园内的海湖、西钢、火烧沟和宁湖等4块湿地的健康综合指数分别为0.76,0.68,0.56和0.63;从湿地指标的净影响值看,服务功能指标的改善幅度最大(0.17),生态环境指标恢复程度最小(0.07)。以上研究对湿地公园未来差异化和精准化管理提供了重要基础数据。

Abstract:

Wetland health is an important indicator reflecting the overall state of the wetland ecosystem,which provides an important basis for wetland restoration and scientific management.Taking the Qinghai Xining Huangshui National Wetland Park (HNWP) in western China as the research object,this paper constructs a Comprehensive Health Index (CHI) that consists of 20 indicators from ecological environment,service function and social environment,and evaluates the health status after the implementation of the wetland restoration and restoration project after 5 years.Analytic Hierarchy Process (AHP) and Expert Consultation Method (ECM) were utilized to determine the weight of each index.Based on field data,experimental data and questionnaire data collected from wetland areas of HNWP in 2013 and 2018,Net Variation Value (NVV) was applied to evaluate the ecological restoration effect of the sampling area.Results showed an obvious improvement from Normal status (0.45) in 2013 to Good status (0.76) in 2018.The CHIs for Haihu Wetland,Xigang Wetland,Ning Lake and Huoshaogou Wetland are 0.76 (Good),0.68 (Good),0.63 (Good) and 0.56 (Normal),respectively.The largest improvement appeared in functional indicators (NVV=0.17) and the least improvement appeared in eco-environmental indicators (NVV=0.07). The above research provides an important basis for the future differentiation and precise management of the wetland park.

Key words: restoration assessment, comprehensive health index, Huangshui National Wetland Park
