Abstract
Vegetation cover is an important component and the best indication to the region ecological environment. The paper adopts a new method of integrating remote sensing technology and composite index appraisal model based multiple linear regression for quantitatively evaluating the regional vegetation ecological environment quality(VEEQ). This method is different to the traditional ecological environment research methods. It fully utilizes the advantages of quantitatively remote sensing technology, directly extracts the key influencing factors of VEEQ, such as vegetation indices (RVI, NDVI, ARVI, TMG), humidity indices(NDMI, MI, TMW), soil and landform indices(NDSI, TMB, GRABS) as the evaluating parameters from data the Landsat 5/TM remotely sensed images, and then puts these factors mentioned above into the multiple linear regression evaluating model. Ultimately we obtain the VEEQ evaluation rank figure of the experimental field-part of Qingjiang region. The handy multiple linear regression model, is proved to be well fit the experimental field for the vegetation ecological environment evaluation research.
