选取20项评价指标，运用PSR模型构建了广东省佛山市土地生态安全评价指标体系，通过熵权法和综合指数法测算佛山市土地生态安全综合指数。结果表明：①佛山市2004年至2011年土地生态安全综合指数总体上有下降的趋势，由2004年的0.5108下降到2011年的0.2452，说明佛山市土地生态安全总体呈下降趋势，由预警进入重警状态；②研究时间段内佛山市土地生态安全状况总体较差，2004年至2011年一直处于有警状态，土地生态系统正面临着资源、环境和人类的威胁和挑战。

PSR model was used to build up the indices system of land eco-security in Foshan city of Guangdong province with 20 indices selected.Through the entropy method and comprehensive index method , the comprehensive index of land eco-security could be calculated.The results show that:(1)the comprehensive index of ecological security of land in Foshan city falls from 0.510 8 in 2004 to 0.245 2 in 2011, which indicated that the situation of ecological security of land worsened from ⅢtoⅠ;(2)the ecological security of land in Foshan city encounters danger during the research years from 2004 to 2011 as a whole, the land ecological system is confronted with threats and challenges from resources, environment and human beings.
