| 摘 要： | 植被是联结土壤、大气和水分等要素的自然纽带,更是自然生态系统中最活跃的因子,植被变化可用来揭示环境的演化,并且能在全球变化研究中起到“指示器”的作用.本研究利用遥感影像获取NDVI数据,借助遥感与GIS等现代手段,运用多种方法对渭干河流域1989-2007年植被覆盖变化特征和发展趋势进行了定量研究,最终得出渭干河流域植被覆盖时空变化规律.

| Abstract: | Vegetation is join ties of natural elements such as sail,air and water,is the most active factor of natural erosystemsovegetation can be used to reveal the evolution of environment,and is able to play in the global change research ＂indicators＂ .The study of NDVI data obtained using remote sensing image,with the help of remote sensing and GIS, and other modern means,using various methods on the 1989--2007 area of weigan River basin vegetation change characteristics and development trends of quantitative research,came to the vegetation covers spatial and temporal changes of weigan River basin. |
