干旱区绿洲土地覆盖变化遥感应用研究——以新疆于田绿洲为例

Study of Land-cover Changes Using Remote Sensing Technology in Arid Area——Xinjiang Yutian County For Example.

从人地关系理论出发以土地利用变化为切入点通过野外调查和遥感动态监测对干旱区绿洲土地覆盖变化规律进行了研究。在考察数据和对遥感图像的分类结果的评价的基础上对干旱区绿洲土地利用/土地覆盖空间动态变化进行规律性分析提出只有协调人地关系、加强区域地理建设才是使干旱区绿洲地区避免荒漠化的唯一道路。

This article proceed from men-earth relationship theory, land use change as breakthrough point, through field surveys and remote sensing dynamic monitoring study on the land - cover changes in Arid Oasis Region. on the basis of field survey data and the evaluation of remote sensing images classification, analysed Add Oasis Region land use/land cover changes dynamically and spatially. Last proposed the only way to prevent desertification is coordinate men - earth relationship and strengthen regional geographic building in Add Oasis Region.
