Abstract

Based on information of ecology, environment and socio-economics over the Hutuo River Basin from 2000, we analyzed factors influencing ecosystem health, used entropy method to develop index weighting scheme of ecosystem health assessment, and evaluated ecosystem health in this basin. Finally, based on the ecological regionalization, some measures for different ecological function sub-region were advanced to protect the basin ecology and recover basin ecosystem. Evaluation results are consistent with the actual situation, indicating that our method is suitable for ecosystem health assessment in the Hutuo River Basin. The resulting data provide scientific basis for integrative ecosystem management of the Hutuo River Basin, so as to provide theoretical and technical support to promote watershed ecological protection and restoration.
