| 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 mod... |
