摘要: 以2005年石漠化监测图斑空间属性数据为本底,利用经过校正的遥感影像数据,对2011年乐业县发生变化的图斑进行区划,再实地核准图斑界线,调查各项监测因子,通过对空间属性数据发生变化的图斑进行汇总统计,获取全县本期石漠化土地的面积及分布信息,并与前期数据进行对比分析。结果表明:全县石漠化土地面积减少5 337.0hm2;由石漠化转变为潜在石漠化的改善型面积为6 909.5hm2,为主导变化因素,全县石漠化总体呈现顺向演替的态势。

Abstract: In order to obtain monitoring data of rocky desertification in Leye county in 2011,this paper used the remote sensing image and the data of rocky desertification collected in 2005 for field survey.We analyzed the dynamic changes of rocky desertification in the Leye county and couducted the zonation of the changes.Through the analysis and contrast,the area of rocky desertification was reduced by 5337.0hm2.The area transformed from rocky desertification to potential rocky desertification was 6909.5hm2,which was a dominant factor in the process of dynamic changes.The rocky desertification has shown a decreasing tendency.

Key words: rocky desertification, dynamic change, analysis, Leye county
