基于遥感和GIS一体化技术的三峡库区土地利用变化研究

The Changes of Landuse Degree in Three Gorges′ Project Area Based on the Integrative Techniques of Remote Sensing and GIS

采用遥感和GIS一体化技术 ,即以遥感实时数据为基础 ,以GIS技术为手段 ,对三峡库区 15年 (1986～2 0 0 0年 )的土地利用变化状况做了研究和分析 ,旨在为当地政府或管理部门提供土地资源合理开发、利用和正确管理的理论依据和科学方法 ,同时也为山区土地利用时空变化研究提供方法借鉴。

This paper is based on an achievement of knowledge innovation project of CAS named the space-temporal information analysis of territorial environment by Remote Sensing and pre-research of relative theory and technique of digital earth (part of Southwest China). With the support of core database of the landuse types change, taking Three Gorges′ Project Area as investigated region, the characteristics of landuse degree changes were studied and analyzed deeply from 1986 to 2000 by using the integrative techniques of Remote Sensing and GIS. The core purpose of the article is to provide the theoretic basis and scientific methods of rational development, utilization and management of land resources for the local government and administration section. At the same time, it also provided methods for reference in the space-temporal variation of landuse in mountainous area.
