On the basis of the comprehension of the meaning of health on land use system,adopting the PSR model,then an empirical analysis was conducted in Fujian Province from 2005 to 2014.The results showed that the composite index of Fujian Province from 2005 to 2014 have a general small upward trend,and the composite index inceased from 0.121 to 0.143.The land use system of Fujian Province is"sick".The pressure index always showed a downward trend,while status index and response index a rise trend.The degree of disorder of the status system and response system had a declining trend,while the state of the system obstacle degree lower than the system response degree.And the degree of disorder of the pressure system of rising trend.In the long run,social and economic development level and intensive land use status will become the main obstacle factors.%基于对土地利用系统健康评价内涵的理解,采用PSR模型对2005-2014年福建省土地利用系统的健康状况进行评价及障碍因子诊断.结果表明:2005-2014年福建省土地利用系统综合指数总体呈现小幅度上升趋势,综合指数从0.121增加到0.143,福建省土地利用系统的健康等级为“病态”;压力指数总体呈现下降趋势,状态指数和响应指数均呈现上升趋势;系统状态和系统响应的障碍度呈波动下降趋势,且系统状态的障碍度比系统响应的障碍度低,而系统压力的障碍度呈现上升趋势;从长远看,社会经济发展水平及土地集约利用状况将成为主要障碍因子.
