沙地遥感影像判读与类型划分初探

本文结合应用遥感技术编制土壤侵蚀图的研究,讨论了沙地遥感影像判读与类型划分的基础理论,及沙地遥感类型界线划分的原则和依据。并运用遥感信息解译原理,建立了卫星影像与沙地类型界线的关系。从而确定了本地区的沙地区域地理相关位置。同时论证了利用遥感技术划分沙地类型界线是可行的,也是可靠的。

A primary Discussion on the Remote Sensing Image and Classification of Sand Lands

This paper discusses the basic theory of remote sensing image reading and classification of sand lands,the principles and bases of the boundary classfication of remote sensing types in close connection with the studies of compiling soil erosion map using the remote sensing technology.Also,the interpretion principles of the remote sensing information are used to establish the relatingships between the satellite image an the type boundary of sand lands.The geographic correlative lccations of the sandy area are determined in this region.Yhis paper also confirms that using remote sensing technology to classify the type boundaries of sand land is feasible and reliable.
