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
