摘要: 以黄土丘陵沟壑区典型小流域定西市安家沟小流域为研究对象,参照压力-状态-响应(PSR)模型,结合区域生态环境特征,从环境资源条件、社会经济水平和生态环境状况3个方面,选择了25项指标,分4个层次构建了表征黄土丘陵区生态安全的评价指标体系,以期对黄土丘陵沟壑区小流域生态系统健康评价提供依据。

关键词: 黄土丘陵沟壑区, 小流域, 生态系统健康, 评价指标

Abstract: Taking the typical small watershed Anjiagou in Dingxi city of Gansu in hilly gully region of loess plateau for example, based on the PSR(Pressure-State-Response) model and the ecological environment characteristics of the region, the indicator system of ecological security of the loess hilly areas was established in such three aspects as the conditions of resource and environment, social and economic development level and the degree of the ecological balance, which included 4 levels and 25 indicators, aiming at providing some references for evaluation of small watershed ecosystem health in loess hilly-gully region.

Key words: hilly gully region of loess plateau, small watershed, ecosystem health, diagnostic indicator
