摘要
Abstract
With Kunming City, Yunnan Province as an object, adoping "Pressure-State-Response" model which was put forward by UNEP and OECO, based on relevant safety evaluation theory, the ecological safety evaluation index system was constructed, including 3 layers and 29 indicators, and the principle component analysis method-was used to evaluate the ecological safety of Kunming City during 2006 -2010. The results showed that the comprehensive scores were -0.546, -1.240, 2.865, 1.636 and 2.239, which indicates a decrease-upgrade-decrease-upgrade trend. The general situation of ecological safety in Kunming City is fluctuant,so investment should be increased in eco-environment in Kunming City.关键词
