摘要: 基于青海省黄南地区MODIS遥感影像图,通过ArcGIS提取区域归一化植被指数NDVI,结合青海省林业资源调查结果,分析区域NDVI和黄南地区灌木林优势树种生物量之间的定量关系。结果表明,NDVI与灌木林生物量显著性相关,拟合两者的回归模型,金露梅、沙棘、山生柳、杜鹃树种的最优模型分别为三次函数曲线,幂函数曲线,复合函数曲线和三次函数曲线模型。

Abstract: Based on the area normalized difference vegetation index from the remote sensing image and the investigation results of the forest inventory in Qinghai Province,ArcGIS and SPSS software are used for analyzing the quantitative relationship between NDVI and biomass of superiority species of shrubbery in Qinghai province and fitting the regression model between them.The results show that NDVI and the biomass of shrubbery have a significant correlation.The optimal models of fruticosa,seabuckthorn,salix oritrepha and rhododendron are respectively cubic function curve,power function curve,compound function curve and cubic function curve.

Key words: NDVI, remote sensing, shrubbery, biomass, Qinghai
