中文摘要：
在PSR模型框架下,构建区域土地利用生态安全评价的指标体系,使用AHP法确定指标权重,采用综合指数法对福建省及其9个设区市的土地利用生态安全状况进行评价.结果表明：福建省土地生态系统已受到一定的破坏,服务功能和生态结构尚能维持,但抵抗干扰的能力有所下降.内陆地区土地利用生态安全水平明显高于沿海地区,自然地理环境、土地利用方式、经济发展实力和人文因素共同影响生态安全水平.人口压力、工业和农业对土地的污染、粗放式的经营方式是福建省土地利用生态安全的主要限制因素.
英文摘要：
The evaluation index system of land use eco-security was established under the PSR model framework.With the adoption of the AHP method,the weight of every index was calculated.Then the land use eco-security levels of the whole Fujian province and 9 cities were evaluated by the comprehensive index method.The results indicated that the ecosystem in Fujian province has been damaged to some extent.The service functions and ecological structure are able to be maintained,but the capability of resistance to interference is slightly reduced.The situation of inland region was higher than the coastal area.The land use eco-security level was affected by physical geography environment,land use pattern,economic development strength and humanistic factors.The main limited factor of land use eco-security in Fujian province included population pressure,the pollution from industry and agriculture,and the extensive use pattern.
