摘　　要：目前,环境资源问题已经对我国建设"和谐社会"构成了严重挑战,如何选取合适的评价指标体系和构建生态评价模型对生态系统进行准确的评价是困难的,也是十分必要的。从生态系统的平衡、波动、干扰及阈值等基本特点出发,构建了区域生态质量评价指标体系包括生产能力指数、服务功能的稳定度指数和人口压力指数三大指标。Today, environment and resource problem have been serious challenges for the construction of ‘harmony society＇ of China. How to select ecosystem assessment indices and how to evaluate the ecosystem quality of China are very difficult. Based on ecosystem basic service （supply ability）, ecological equilibrium, fluctuation, threshold, and disturbance（including natual disturbance and man- made disturbance）, the paper designed ecosystem assessment indices including productive index, serviee stability index, and population pressure index.
