Abstract

This paper analyzed the spatial distribution law of NDVI in Sichuan province based on the GIS and RS technology. Firstly, the value of NDVI in Sichuan province was calculated based on the MODIS raster data; Secondly, the DEM(digital elevation model) was generated by the contour; Thirdly, the classification data of geography was extracted based on the GIS technology, such as slope, aspect , altitude and the spatial distribution law of NDVI by using the spatial analysis functions of GIS, include the distribution law in different altitude, slope degree and aspect. At last, the conclusion of the spatial distribution law of NDVI was drawn and the improve methods and suggestions to the regions of low value of NDVI were promoted in the article.
