| 摘 要： | 采用扩展型PSR模型构建了土地资源生态安全评价指标体系，运用基于层次分析法的综合评价模型计算了广州市土地资源生态安全综合指数，并在此基础上进行了相关性分析。研究表明，1996~2006年广州市土地资源生态安全水平稍有好转；压力、状态、响应指数呈现不同的变化幅度；人类社会经济活动的响应对土地资源生态环境的影响较大。基于此，提出了合理的建议。

| Abstract: | The evaluation index system of land resource eco-security was constructed by using improved PSR model.The comprehensive indices of land resource eco-security in Guangzhou City were calculated by adopting comprehensive evaluation model based on Analytic Hierarchy Process,and correlation analysis was made then.Results showed that land resource eco-security level in Guangzhou City was improved from 1996 to 2006.Pressure indices,state indices and response indices showed different ranges of variation.The respons... |
