摘　　要：以喀斯特地貌发育典型的贵州省平塘县为研究对象,以乡镇为评价单元,根据自然-社会-经济(NSE)模型构建生态安全预警评价指标体系,采取熵权层次相结合法确定指标权重,运用改进突变级数法计算生态安全预警指数,旨在为平塘县生态可持续发展提供理论参考.结果表明:2011—2013年平塘县各乡镇生态安全预警指数为0.6~0.8,均属于中警,其中卡罗乡、新塘乡、西凉乡、四寨镇生态安全预警指数呈增大变化趋势,生态安全得到改善;大塘镇、掌布乡生态安全预警指数呈减小变化趋势,生态安全略显退化;平湖镇、苗二河乡、卡蒲乡等呈先减小再增大的变化趋势,生态安全呈波动变化.Taking the typical karst landform development Pingtang County in Guizhou Province as the research object, taking the villages and towns as evaluation unit, constructing the ecological security early warning evaluation index system according to natural-social-economic（NSE） model, using entropy weight method and hierarchical analysis method to determine the index weight, using the improved catastrophe progression method to calculate the ecological security early warning index, to provide a theoretical reference for the purpose of ecological sustainable development in Pingtang county. The results show： the ecological security early warning index is between 06~0.8 in Pingtang County from 2011 to 2013 year, belong to the middle warning. The ecological security early warning of Kalou Village, Xintang Village, Xiliang Village, and Sizhai Town shows a trend of increase, and ecological security has improved. But the ecological security early warning of Datang Town and Zhangbu Village shows a trend of decrease, and ecological security shows a slightly degraded trend. The ecological security early warning of Pinghu Town, Miaoer Village, and Kapu Village, etc shows a change trend of decrease first and then increase, and ecological security shows a trend of fluctuation.
