Comprehensive Index Method

Some eco-environmental factors are analyzed by RS, and population and GDP spatial distribution are obtained from statistical data. By combining AHP methods for determining weights, comprehensive index method is used to evaluate the eco-environmental quality of Yellow River Delta (YRD) on three scales: raster, administrative region, and delta. Results show that: Eco-environmental quality of YRD lies in moderate level. In three terms (1996, 2000, 2004), it was the best in 1996, and decreased to the worst in 2000, and then increased in 2004. In the delta, Estuary area and Dongying area were poorer than Guangrao county and Liji county.
