摘　　要：为了探明贵阳市植被覆盖的发展和变化，采用 ENVI 软件对贵阳市1990年和2007年的Landsat TM 遥感影像进行土地利用分类和植被覆盖度分级，分析植被和其他土地利用类型以及植被覆盖度各等级之间的转移情况。结果表明：较之1990年，2007年贵阳市的植被覆盖面积增加了11．10％，植被覆盖面积由中、低等级（0～3级）向高等级（4～5级）转移，转移面积达407．82 km2。Landsat TM remote sensing images of Guiyang City in 1990 and 2007 were used to investigate its development and change of vegetation coverage,and envy software was used to classify the land use and vegetation coverage,analyze the transition of vegetation and other types of land use,as well as each grade of vegetation coverage.The results showed that vegetation area of Guiyang City increased by 11.10% in 17 years.And area of low and middle-grade vegetation coverage（0~3）reduced by 407.82 km2 , while the high （4~5）had increased the same accordingly.
