摘要 以丰都县1997-2004年的土地利用现状为依据,在定性分析土地利用变化对生态环境造成的影响基础上,采用层次分析法构建土地利用变化生态环境影响评价体系,进而对丰都县土地利用变化对生态环境的影响进行评价。研究表明:近几年丰都县土地利用变化对生态环境的影响正效应显著,但是参照国家生态区的标准,丰都县的生态环境质量还处于相对较低的水平。 AHP (analysis hierarchy process) was employed to construct a system of environmental impact assessment for land use change, based on a quantitative analysis of the effects of change in land use on eco-environment in Fengdu country from 1997 to 2004. The results showed that the change in land use in this country in recent years has had a significant positive influence on the eco-environment; however, compared with the national standard for eco regions, the quality of the eco-environment in the country has remained at a comparatively low level.
