摘　　要：以黑龙江省东部煤炭城市鸡西市为例,选取16个典型评价因子,遵循客观、科学、简明可行原则,利用压力-状态-响应(PSR)框架结构模型构建土地生态安全评价指标体系,采用极差法对评价指标数据进行归一化处理,以熵值法计算各评价指标的权重,最终确定2008—2014年研究区土地生态安全综合指数。结果显示:鸡西市土地生态安全综合指数呈现逐年提高的趋势。Taking coal-resource-city Jixi in eastern Heilongjiang Province as an example, 16 typical evaluation factors were selected. According to the objective, scientific, concise and feasible principles, Pressure-State-Response （PSR） frame structure model was used to establish land ecological security evaluation index system. Normalization processing of evaluation index data was carried out by Range method. Weight of evaluation index was calculated by entropy method. Finally the comprehensive index of land ecological security in 2008 - 2014 was finally determined. Results showed that comprehensive index of land ecological security in Jixi City presented the trend of increasing year by year.
