| Abstract: | Based on the latest research of present Eco environmental Situation at home and abroad and analysis of the characteristics of Environmental Situation in China with the principle of index selection, a set of indices on the Eco environmental Situation in China has been identified. Then 14 county unit databases are set up, including two types: 2 spatial databases and 12 attribute databases. And the mathematical models for each index has been developed. With the powerful systematic analytical tool, GIS, and database management system, this paper classifies each index into five degrees and integrates them into a map according to their respective rights by county unit, which is the distribution of the Eco environmental Situation in China. Finally this paper analyses the distribution of Eco environmental Situation in China, draws compellent conclusions on this methods and discusses some details. Some items that need to be improved afterwards are put forward. |
