中文摘要：

土地资源的可持续利用是当前国土资源开发与保护的主要内容，土地资源生态环境安全是土地资源可持续利用的基础，而土地资源生态安全评价是土地资源生态安全研究核心内容。本研究以云南省统计年鉴为数据源，首先采用“驱动力一压力一状态一影响一响应”模型进行了滇中经济区土地资源生态安全评价指标体系的构建，进而利用投影寻踪法来确定土地资源生态安全评价权重。结果表明，滇中经济区42个县区的土地资源生态安全态势分布不均匀，即便是都处在经济发达的昆明市，资源状况也有较大差异；昆明市、楚雄州、玉溪市、曲靖4个市的土地生态安全利用压力层、状态层、响应层方面差距大；驱动力层有差异但差异较小，影响层几乎没什么差异。

Abstract： Sustainable use of land resources is the main content of the development and protection of land resources and ecological environment security of land resources is the basis of sustainable use of land re- sources with ecological security evaluation of land resources as it＇s core content. In this paper, the Yunnan Statisti- cal Yearbook was used as our original data and DPSIR （ Driving forces - Pressure - State - Impact - Re- sponse） model was firstly used to construct ecological security evaluation index system of land resources and then the projection pursuit clustering method was used to determine weights of ecological security evaluation index. The results show that, ecological environment security of land resources is uneven distribution in all 42 counties of Central Yunnan Economic Zone even in developed area such as Kunrning. The pressure layer,＇ state layer and re- sponse layer of and impact layer of almost no difference. Kunming. The pressure layer,＇ state layer and re- differ a lot with driver layer of small difference.
