Evaluation on Ecological Vulnerability of the Vegetation in Subei Lake Watershed Based on Analytic Hierarchy Process
摘要
Abstract
[ Objective] The research aimed to evaluate ecological vulnerability of the vegetation in Subei Lake watershed based on analytic hierarchy process (AHP). [Method] Started from actual situation of the vegetation ecology in Subei Lake watershed, using constructed evaluation index system of the vegetation ecology in Subei Lake watershed, based on AHP, weight of the indicator at each layer was determined. Comprehensive index method was used to count ecological vulnerability of the vegetation in each evaluation unit. [ Result] Ecological vulnerability of the vegetation was divided into four ranks, such as extremely fragile, highly fragile, medium fragile and low fragile in Subei Lake watershed. Extremely fragile area distributed in beach near Subei Lake. Burial depth of the groundwater level was generally less than 1.0m. Relationship between vegetation and groundwater was close in the zone. Low fragile area scattered in ridge zone around Subei Lake watershed. Burial depth of the groundwater level was 10. 0 - 40. 0 m. Relationship between vegetation growth and groundwater depth was not obvious. Groundwater depth had the most sensitive influence on vegetation ecology, and was the key factor between utilization of the groundwater resources and eco-environment protection in study area. [ Conclusion ] The research provided scientific basis for regional eco-environment protection, reasonable development and utilization of the water resources, coordinated development of the economy and society.关键词
