摘要：
Using the two periods of TM images and investigation of Hulun Lake, vegetation index, TS, NDMI, NDSI, slope are choosed as indicators. Grassland eco-environmental quality assessment model is builded by multiple linear regression to assess quality in the study area. From the evaluation results, poor and bad area increased from 9% to 17%, meanwhile, good and general area decreased from 89% to 81% in five years. The grassland eco-environmental quality in the study area is getting worse and worse.
