摘要

江河源区是近年来西部生态环境研究的重要地区之一

也是我国两大河流上游的水源涵养区。基于 RS和GIS对该地区两个不同时期 (1986和2000年)生态环境进行对比分析。采用TM影像在同一个分类系统下进行信息提取。分类系统共分8类 34个类型

原则是根据地域特点来划分的

主要有:(1)地域差异原则;(2)分区与分类相结合的原则;(3)综合因素与主导因子结合的原则。通过建立操作性较强的影像解译标志

利于今后对江河源区生态环境进一步研究和和监测。

Abstract

Recently

the source area of the Yangtze river and the Yellow river is one of the important areas being researched on environment in the west China

as well as the water conservation on upper reaches of the two rivers. Researching environment must take them into account

because the directly affects the improvement of environment

such as landform

soil

temperature

moisture and erosion etc. Contrasting to the former that took much account on the land use/land cover in the area

the study contrast state by means of remote sensing

utilizing TM images to extract information through the same classification system. The system is divided into eight classes and thirty four types. According to characteristics of the region

the system contains:(1) area diversity principle; (2) combination principle between regionalization and class classification; (3) combination principle between synthetically and dominant factors. It is necessary to establish superior manipulative ability of interpretation marks on the studied area

and beneficial to make further monitor and research
