Abstract

According to “Technical Criterion for Ecosystem Status Evaluation” issued by State Environmental Protection Administration, on the basis of Arcgis platform, using the comprehensive evaluation index method, the paper takes Dongsheng district as a case, selected biological richness index, vegetation coverage index, land stress index, water network denseness index and pollution load index to evaluate the quality of ecological environment. The evaluation result shows that the ecological environment quality of Dongsheng district is "normal", the degree of vegetation coverage is moderate, the biological diversity is general, and it is suitable for human to live, but sometimes exist restrictive factors limit human existence. The ecological index value increased from 52.06 of 2005 to 53.11 in 2014, and land ecological environment quality of Dongsheng district has rising trend from the overall view, but the amplitude variations in the ecological environment condition has no obvious change, land ecological environment is good, the land ecosystem structure is complete, and its function is basically perfect.
