Abstract :
The use of satellite remote sensing technology to Lijiang River to explain the conditions of ecological environment, a comprehensive analysis of the forest, vegetation, soil ecological environment for the main types of situation, application software ERDAS 4 years of supervised classification images to calculate the Normalized Difference Vegetation Index (NDVI), derived from 2002 to 2008 time span increased by 19.63% forest area, bare land area decreased 29.46% and 248.89% increased in water area which indicating that Lijiang River has improved the ecological environment conditions change nearly 8 years.
