摘要

三峡水库是我国特大型水利枢纽工程。三峡工程建成后

随水库运行将在库区两岸形成垂直落差30m的消落带

面积达300km

。结合三峡库区消落带的气候、坡度、水深、地貌等区域基本特征

以遥感数据为基础

以GIS技术为手段

对三峡库区消落带土地资源进行分析研究

划分出消落带土地资源的6种类型

即硬岩型消落带、软岩型消落带、松软堆积型消落带、库尾松软堆积型消落带、湖盆松软堆积型消落带、岛屿松软堆积型消落带

并给出了不同类型消落带的可持续土地资源利用模式。

Abstract

The three Gorges Reservoir is the largestwater conservancy and control projectin China. After the three Gorges Projectis completed

a 30 m high water-level-fluctuating zone (WLFZ) will appear along the two banks and the area of the WLFZ reaches about300 km2. By using GIS and RS techniques

land resources in the WLFZ are analyzed and classified in view of climate conditions

water depth in the WLFZ

slope

and soil textures of the land. The WLFZ is classified into six land models: rock exposed regions model

softrock exposed regions model

moderate and gentle model

reservoir backwater area model

unique landscapes model

and island model. The classification of the WLFZ of the three Gorges Reservoir provides a theoretic basis and scientific methods of rational development.
