- Abstract:
-
Ecosystem health assessment is one of the hot issues on the ecosystem management and the macroscopic ecology research at present, as well as the key to the sustainable development of regional ecosystem. We took the oasis-desert ecotone of Minqin County as an example, built the ecosystem health evaluation system, and used the entropy value method, maximum difference dormalization method and multi-factor comprehensive evaluation method to evaluate the ecosystem health condition. The results showed that the evaluation results were consistent with the actual situation in the study area, and the comprehensive index of ecosystem health in the oasis-desert ecotone was in the state of health in Minqin County based on the PSR model, which is rising. The ecological environment of the oasis-desert ecotone in Minqin County is good on the whole; meanwhile, it provided the reference basis for the ecosystem health evaluation of the other oasis-desert ecotone.
