宁夏固原清水河谷地区地质地貌遥感解译初探

Preliminary geological and geomorphological interpretation of remote sensing for Qingshui valley in Guyuan city, Ningxia

利用遥感技术,以法国Spot5和日本Alos卫星数据为基础,建立固原清水河谷地区地质地貌遥感解译标志,辨识确定了流域内中低山、低山、黄土丘陵、黄土塬、黄土梁和河谷阶地共6种主要地貌组成类型.统计分析认为主导地貌类型为黄土梁、河谷阶地和构造侵蚀山地;地层分布为第四系、中新统;清水河断裂,海原断裂,南、西华山—六盘山大断裂3个主要断裂带.为"宁夏固原盐化工基地水资源勘查"建设规划和固原盐化工基地的选址提供了重要数据和分析结论.

Using remote sensing technology, based on France Spot5 and Japanese ALOS satellite data, remote sensing mark of Qingshui valley in Guyuan is established to interpret geological and geomorphologic information. And six major types of landscape composition were identified and determined, include low mountains in the basin, low mountains, loess hilly Loess Plateau, Loess and valley terraces. Statistical analysis that the dominant landform types Loess valley terraces and tectonic Erosion Mountain, stratigraphic distribution is Quaternary and Miocene. Qingshui river fault, Haiyuan fault, South, West Mountain- Liupanshan fracture are three major fault zones. Research results are important data and conclusions for water resources exploration and planning in Guyuan salt chemical base construction project and site selecting of Guyuan salt chemical base.
