Normalized Difference Vegetation Index (NDVI) and Index Based Builtup Index (IBI)
was built to evaluate urban eco-environment quality based on remote sensing data and datasynthesized by principal component analysis. It was applied in Zhongshan City
Guangdong Province. The Landsat TM images in different years were used to explore the applicability and accuracy. The results showed that this method can reflect the variation of regional eco-environment quality. The eco-environment quality of Zhongshan in 1994 and 2009 was both at a good level. The overall eco-environment quality in 2009 was better than in 1994. In 2009
the area with poor eco-environment quality decreased
but the area of eco-environmental degradation increased in local region. The coordinative development degree between environment and economy was at a good level in 1994
but declined generally in 2009. Serious imbalance between eco-environment and economic development occurred in some towns.
