Early warning theory on regional eco-environmental issues and its application

Abstract

Abstract: Principles of early warning on regional eco -environmental issues are descussed in the paper. For this warning,the regional sustainable development ability(SDA)is used as a comprehensive index, which is weighed up by loading capacity, stability, buffer capacity and productivity. Natural resources,ecological degradation,environmental pollution and social -economic indices are selected to establish an index system for evaluating and early warning regional eco -environmental issues and, the eco-environmental quality of various provinces and districts in China is evaluated, put in order and early warned.

Key words: Early warning, Regional eco-environmental issues, Index system
