Forest vegetation spatial and temporal pattern analysis based on NDVI in Jiuzhaigou

摘要

This paper takes Jiuzhaigou area for example, selecting Landsat remote sensing images in phase time about years of 1999, 2002, 2006 and 2007, using ENVI and ArcGIS software for image data processing, making spatial and temporal characteristics and distribution pattern analysis of vegetation index NDVI of Jiuzhaigou forest. The result shows that NDVI of Jiuzhaigou forest has obvious characteristics of spatial and temporal variation. The paper provides the analysis process and reference to the forest vegetation research of other areas.
