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.关键词
