石漠化地区小流域生态系统健康定量评价
Quantitative evaluation on ecosystem health in small watershed in rocky desertification area
摘要
Abstract
A case study were conducted in Zhulinhe small watershed in rocky desertification area. Total 15 factors were selected as evaluation indices from three aspects; resource-environment, social-economy state, and eco-comprehensive function. Evaluation index system for small watershed ecosystem was established to give health assessment. The method of high precision of standard deviation coefficient was used to calculate the weight, and grey relational analysis method was introduced to build comprehensive evaluation model for watershed ecosystem. Ecosystem health situation was evaluated quantitatively. Results showed that the watershed ecosystem was relatively stable and the health index has an increasing trend from 0. 341 5 in 2000 to 1 in 2008.关键词
