- Abstract:
-
This paper studied the ecology environmental quality based on ETM+ image,classified the land cover types of Tangshan region,chose four indices of biology abundance,percentage of vegetation cover,soil degradation,and soil moisture as indicators,computed weight-coefficient to each factor evaluated with method of principal component analysis,evaluated the ecology environmental quality to Tangshan region with comprehensive index model.On the fact of ecology environmental quality of Tangshan region and relation between land cover type and ecology environmental quality,the effective way to improve the ecology environmental quality of Tangshan region is that overspreading of land use in cities and towns must be controlled,alkaline land on the beach must be improved,mineral resources exploitation should be supervised and regulated,the recovery of ecological environment in mining area should be valued.
