Evaluation of Ecological Environment in Jingxin Wetland Using Analytic Hierarchy Process

摘要

[Objective]The study aimed to assess the ecological environment in Jingxin wetland using analytic hierarchy process (AHP). [Method]Based on the field survey on Jingxin wetland in the downstream of Tumen River, as well as domestic and international indicators and methods of wetland ecological evaluation, ten indicators reflecting the environmental protection function, functions of the ecological system and social and cultural value of the wetland were selected to evaluate the ecological environment of Jingxin wetland using AHP. [Result] The comprehensive evaluation index ( CEI ) of Jingxin wetland was 0.7124, namely 0.7CEI≤1.0, showing that the ecological environment in Jingxin wetland was better on the whole. Among the ten indicators, the functions of regulating flood, water supply, climate regulation, tourism and being an important animal habitat played important roles in the determination of the wetland value. [Conclusion]The research could provide theoretical foundations for the protection of ecological environment in Jingxin wetland.
