摘要
目前,归一化植被指数NDVI作为一种遥感手段已经广泛应用于社会生产生活的多个方面.在综合大量国内外文献的基础上,总结了从遥感影像中提取NDVI的方法以及在提取过程中要注意的问题;气温、降水等气候因素对NDVI的影响以及NDVI自身合成计算、与气候因子相关系数计算的分析方法;列举了NDVI在植被监测、土地覆盖变化、荒漠化研究、净第一性植被生产力等几个方面的应用现状,并列出了NDVI在研究应用中的优势、存在的缺陷及改进NDVI缺陷的研究.
As a way of remote sensing, Normal Different Vegetation Index （NDVI） was widely used on many fields. The method to abstract NDVI from remote sensing images was summarized. A series of technical details including the influences of temperature and rainfall on NDVI, calculation and synthesis of NDVI, calculation of correlation coefficient between NDVI and climatic factors were summarized. The application fields of NDVI, such as vegetation monitoring, land coverage change, desertifieation and net primary productivity were illustrated. The advantages and disadvantages of NDVI were
