再生资源动态遥感分析方法试验研究

人类大规模的活动与自然资源开发,引起了全球范围内的生态环境以及可更新资源的迅速变化。快速、定量监测这些变化,已成为遥感应用研究新的发展领域。 本文叙述了有关资源环境动态遥感监测研究方面的初步探索性工作,主要包括利用图像处理系统,根据专题变化因素的光谱亮度统计进行密度、比值和纹理处理、不同时期遥感信息的复合处理和规一化差值及主成分分析法的“亮度”、“绿度”差值分析;利用地理信息系统,采用覆盖分析和局部更新法进行再生资源变化图件的快速更新,以及为研究再生资源动态变化规律,而进行的多变量相关、区域回归分析方法。

Experimental Research of Remote Sensing Analysis on Renewable Natural Resources Change Monitoring

Global eco-environment and renewable natural resources Change very quickly, which is caused by human activity and exploitation in large scale. Monitoring of these Changes is a new research field of remote sensing application.This paper described a experiment study of remote sensing systematic analysis on natural resource and environment Change monitoring. Main methods concern changed factor extraction through the brightness statistics, ratio and texture analysis; matching multi-temporal remote sensing data, normalized difference comparison, "brightness" and "greenness" difference analysis of principal components method by using image processing system; updating renewable natural resources changed map through overlaying or partly revising multi-temporal maps by using geographical information system; establishing mathematic model, such as: variable correlation regional regression and tendency surface analysis etc., for researching renewable natural resource change law.
