基于遥感数据的西南地区第四纪残坡积层分布与利用——以四川省盐源盆地为例

The Distribution and Utilization of Quaternary Residual and Slope Sediments in Southwest China Based on Remote Sensing Data:a Case Study of Yanyuan Basin in Sichuan Province

在完成四川省盐源盆地第四纪地质遥感调查的基础上,通过对第四纪残坡积层的遥感调查成果分析研究,建立了第四纪残坡积层遥感识别的影像特征,掌握了第四纪残坡积层的分布特点。结合区内第四纪残坡积层的土壤结构、基岩性质和基础地质背景特征,认为在当前我国用地少且不断减少的环境下,开展第四纪残坡积层遥感调查,对寻找和开拓新的土地资源潜力地区具有重大意义。

This study was based on Quaternary geological remote sensing survey of the main stream basin （ Yanyuan Basin） in Sichuan. Through remote sensing investigation and analysis of resources and research on Quaternary residual and slope sediments, the authors set up image features of remote sensing recognition of Quaternary residual and slope sediments and got to know the distribution characteristics of Quaternary residual and slope sediments. According to soil structure, rock property and geological background characteristics of Quaternary residual and slope sediments, the authors hold that, as land has become increasingly less in China, the development of remote sensing investigation of Quaternary residual and slope sediments has great significance in that its can find and explore new potential areas of land resources.
