| 摘 要： | 根据龙岩市土地资源特点,基于P-S-R框架模型构建土地生态安全评价指标体系,运用熵权法和综合指数法,对龙岩市2002~2012年土地生态安全进行动态评价,结果表明:龙岩市2002~2012年土地生态安全综合指数呈波动上升趋势,从2002年的"敏感级"上升到2012年的"良好级",期间2004~2008年一直处于"风险级",说明土地生态安全状况不断好转的同时仍不容乐观.在此基础上,提出改善土地生态安全的对策,为龙岩市土地资源合理利用和生态建设提供科学依据.

| Abstract: | According to the analysis of the characteristics of land resources in Longyan City,this paper established a set of evaluation index system based on the P-S-R framework model. Entropy weight method and the integrated model of land ecological security were used to calculate the integrated index of land ecological security from 2002 to 2012 in this area and to evaluate the dynamic security of land ecolo- gy. The results indicated that the land ecological security index went upward with fluctuation in Longyan City during ten years ： From 2002 ＂sensitive grade＂ to 2012 ＂good grade＂ ; during 2004 to 2008, in a ＂risk grade＂. However, the situation was still not optimistic. Therefore, some suggestions on improving the land ecological security were put forward, so as to provide a basis for the reasonable utilization of land resources in Longyan City and ecological construction. |
