摘要

土壤侵蚀是一种长时效的恶性地貌过程

已成为我国最重要的、持续影响面最大的生态环境问题。研究以位于三峡库区库尾的重庆市主城区为例

综合运用RS和GIS技术

解译了1988年、1999年、2009年3期TM、中巴遥感影像

并与数字化的地质图进行空间叠加分析。结果表明:(1)1988-2009年研究区各地层以微度侵蚀、轻度侵蚀为主

总体上呈现好转趋势。(2)研究区地层土壤侵蚀动态变化率内部差异大。(3)从地层与土壤侵蚀的相关关系分析

岩性的软弱性决定了土壤侵蚀的易发性。上、下沙溪庙组

遂宁组以抗蚀性能力弱

摩擦系数低的紫(红)色砂岩、泥岩为主

加之出露面积大

决定了土壤侵蚀的易发性

应是研究区水土保持工作的重中之重。

Abstract

Soil erosion is a long time malignant geomorphologic processes

has become the most important and largest continuous influence of the eco-environmental problems in China.This article took the main of Chongqing city as an example

which was located at the end of the Three Gorges Reservoir.The synthesis utilizes RS and the GIS technology

interpreting the 1988

1999

2009 three periods of TM

CBERS remote sensing

and with the digital geological map of the spatial overlay.The results showed in the following aspects:...
