中文摘要	以2000-2010年三期卫星形像为数据源,结合统计资料研究了最近十多年来贵州省石漠化土地面积变化状况。结果表明:贵州省2010年石漠化土地面积为36473km~2。其中2000~2005年,每年增加335.4km~2;2005~2010年,石漠化面积减少1126km~2,年变化率-0.6%;石漠化综合治理工程初见成效,贵州石漠化发展趋势得到遏制。石漠化内部变化主要集中在相邻等级之间,在短时间内一般不会发生等级跳跃变化,矩阵转变主要发生在等级较低的石漠化等级,强度石漠化转变面积最小,表明石漠化等级越高,治理难度越大。
英文摘要	Rocky desertification has become one of the most serious ecological environment problems for Karst area. Taking Guizhou Province where the rocky desertification is the most serious in South China as the research object,the rocky desertification change characteristics under the ecological treatment and rocky desertification controlling project since 2000 were studied. Data shows that rocky desertification of Guizhou was 36473km~2 in2010,and increased 1677km~2 in 2000 ~ 2005,increased 335. 4km~2 every year; from 2005 to 2010,the rocky desertification area reduced 1126km~2,annual change rate was - 0. 6%; rocky desertification of Guizhou increase trend had reversed,rocky desertification controlling project initial effect had appeared. The internal changes of desertification mainly concentrated in adjacent grades,and had not grade jump change in a short period of time,matrix transformation occurred mainly in the lower grade of rocky desertification,intense desertification change area was the smallest,demonstrating that the higher rocky desertification grade is more difficult to treat.
