摘要
简要介绍了西藏自治区沙漠化普查中所采用的遥感手段,通过对各种遥感信息源的使用比较,详细阐述了普查工作中对沙漠化土地及其它土地类型的判读和解译,并且对本次普查结果进行了精度估算。结果表明,利用遥感手段进行沙漠化土地调查不仅具有现实意义,而且为进一步沙漠化的防治和监测工作提供了准确的数据基础。
Comparing with the kinds of different information sources of remote sensing,this paper elaborates the interpretion and analysis of desertified land and others and then carries on valuation of precision on the general investigation.The result shows that remote sensing technology is a rapid,accurae and economical method for the general investigation of desertification.At the same time,it will be used for monitoring,controlling of desertification in the future.
