摘要
对荒漠化草地的遥感动态监测研究是目前草地研究、监测、管理的热点。选择色达县色柯镇、年龙乡和亚龙乡为研究区,依托色达县第二次土地调查项目,利用RS与GIS技术对色达县草地荒漠化进行了遥感动态监测分析;选取了色达县1994年TM影像和2001年ETM+影像,采取监督分类法,提取了研究区多时相草地荒漠化信息,并对其动态变化过程进行了定量分析,根据影像特征对变化趋势进行预测和分析,并提出科学合理的防治措施。
The research of remote sensing dynamic monitoring for grassland desertification is currently the hot spot of grassland research,monitoring,and management.This paper chose Seke town,Nianlong town,Yalong town of Seda county as study area,relying on the second land survey project of Seda County,using RSGIS technology in the remote sensing dynamic monitoring of grassland desertification in Seda County.The paper selected 1994 TM images and 2001 ETM＋images of Seda County,using supervised classification method,extracted multi-time grassland desertification information in the study area,and taken the dynamic process of quan- titative analysis to predict and analysis the trend of change,according to imaging features,and to make scientific and rational control measures.
