土地利用遥感动态监测技术方法介绍

Introduction to Sense-remoting Dynamic Monitoring Technology in Land-using

采用遥感技术进行土地利用动态监测是一条行之有效的方法。遥感监测方法多种多样,但为了确定变化类型,要引入遥感图像分类方法。遥感分类方法一直是遥感技术方法研究的重要领域。迄今为止,目视解译仍是成功的分类方法;在今后相当长的一段时间内,目视解译分类与计算机自动分类将协调发展。我国土地利用遥感动态监测方法主要采用目视解译、计算机自动分类及目视解译与计算机图像处理相结合的方法,其中,目视解译的方法一直占有重要地位。随着高分辨率传感器的相继问世,利用多平台遥感数据融合进行监测研究将有利于提高分类、监测精度。我国的土地利用遥感监测研究正深入开展,并将在计算机信息提取及监测方法上取得更大的成果。

Sense-remoting is an effective method to carry out dynamic monitoring in land-using. In order to determine variation types, sense-remoting image classification method should be leaded into our country. Major methods of sense-remoting dynamic monitoring in land-using in our country are as follows: visual interpretation, automatic classification by computer and combination of visual interpretation and automatic classification by computer. Among them, visual interpretation plays an important pole. It is suitable for promoting classification and monitoring accuracy by melting multi-table sense-remoting datas. Study on sense-remoting monitoring method of land-using is carrying out in China, which will gain more achievements in information extraction and monitoring method in computer.
