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。
Abstract
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 ecologi-cal security evaluation index system.Normalization processing of evaluation index data was carried out by Range method .Weight of evaluation in-dex 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 .
