Evaluation Index System and Calculation Method of Ecological Environment
5.1 Evaluation Index System of Ecological Environment
Eco-environmental status assessment uses a composite index (Eco-Environmental Situation Index, EI) to reflect the regional ecological environment
The index system includes the biological abundance index, vegetation cover index, water net density index, land stress index, pollution
The load index of the five sub-index and an environmental limit index, the five sub-indices were reflected in the assessment of the region's biological poverty,
The level of vegetation coverage, the degree of water enrichment, the intensity of stress suffered, the pollutant pressure carried, and the environmental limit
Bundling indicators, refers to the region due to the serious impact of human settlements production and safety of ecological damage and environmental pollution incident
