摘要
以重庆市为研究对象，构建了由压力、状态和响应3个要素组成的土地生态安全评价指标体系，采用熵权法和物元模型对重庆市2005～2013年的土地生态安全作出分析和评价。结果表明，2005～2013年重庆市土地生态安全综合关联度都为负值，均在（－1，0）区间，表明重庆市土地生态安全状况均未达到所在的等级，但都具备转化为所在评价等级的条件，2005～2007、2009～2013年的土地生态安全能够向安全转化，2008年的土地生态安全能够向基本安全转化，重庆市土地生态安全的大致发展趋势是向较安全级别转化，与重庆市社会经济快速发展、生态环境保护良好有密切关系。
Abstract
Abstratc Taking Chongqing as the research object, land ecological safety evaluation index system was established including pressure, state and response, land ecological safety of Chongqing during 2005-2013 was analyzed and evaluated by entropy method and matter element method.The results showed that the comprehensive correlation degree of land ecological safety in Chongqing during 2005-2013 was negative( -1, 0), indi-cating land ecological security situation of Chongqing failed to meet the level, but all have conditions transforming into the evaluation grades.The general development trend of land ecological security in Chongqing City is converted to a more secure level, which is closely related to social and economic rapid development and eco-environment protection in Chongqing City.
