Synthetic evaluation of eco-environmental quality in the middle of Jilin Province

摘要：

According to the characteristic of eco-environment in the Middle of Jilin Province and the requirement of societal economic sustainable development and eco-environment protection and recovery,environmental quality evaluation index system is established by the use of different subjects spacial data obtained from multi-sources.Meanwhile,a model of synthetic evaluation of eco-environment is set up based on the grid data with RS and GIS technology.The result of synthetic evaluation is achieved by spatial overlay analysis method.Through the analysis of the result,the trend of eco-environment quality distribution is gained,as well as the quantificational numerical value of the eco-environmental synthetic evaluation on the unit of county and city regionalism.Ultimately,quantitative analysis of eco-environment quality in the region is achieved.
