摘要
该文利用四川省1996-2014年相关统计数据,以PSR框架模型构建全省土地生态安全评价指标体系,熵权法确定指标权重,综合评价法计算土地生态安全综合指数,对区域进行土地生态安全直接评价。结果表明:18a内全省土地整体处于发展状态,土地生态安全持续好转。
By adopting the relevant statistical data within 18 years,we have established land ecological evaluation in-dex system with the PSR structure,by using entropy weight method to make sure index balance and comprehensiveevaluation to count the comprehensive index and direct evaluation the regional land ecological safety. The resultshows that the whole province’s land is in a state of development. The land ecological safety is at a state of gettingbetter.
