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.
