摘要 本文以清江流域为研究区域,基于GIS技术,对清江流域的资源环境空间要素进行分析。研究选择ArcView3.3作为软件平台,探讨了数字高程模型(DEM)的建立,在此基础上进行水文模拟分析以及地貌形态分析,提取了流域的河网,进行了流域剖面图、坡度、坡向和粗糙度图的绘制,揭示了流域内资源环境的隐含信息。总结分析结果,对区域的资源开发和环境保护的可持续性提出建议。 This paper takes Qing river valley as the study area. Based on GIS technology, the spatial factors of the resources and environment of Qing river valley are analyzed. Choosing ArcView3.3 as the software platform we have discussed the construction of the Digital Elevation Model （EDM） On this basis we carry out analyses of the hydrological simulation and landform. Through investigating the river network of the valley and mapping the section, slope, exposure and roughness of the valley, we have unveiled the implied information of the resources and environment in this valley. After summing up and analyzing the results obtained, we put forward our suggestions on the sustainable resources development and environment protection of the region.
