青海湖环湖地区草地植被生物量遥感监测模型
DOI: 10.11821/xb200305007, PP. 695-702
Keywords: 遥感,植被指数,草地,生物量,青海湖
Abstract:
利用青海湖环湖地区2000年陆地卫星TM遥感图像数据和同期野外实测的34处样方产草量数据，分析了遥感植被指数与草地植被生物量之间的相关关系，进而分别建立了遥感植被指数与草地植被生物量的一元线性回归模型和非线性回归模型。研究表明，遥感植被指数与草地生物量之间存在较好的相关性，但不同遥感植被指数与草地植被生物量相关性程度存在一定差别。此外，所建遥感植被指数与草地植被生物量的非线性回归模型在拟合精度上优于一元线性回归模型，且由三次方程得到的非线性回归模型最适用于监测青海湖环湖地区的草地植被生物量。
