基于NDVI与LAI的水稻生长状况研究

Research on Rice Growth Status Based on NDVI and LAI

在水稻反射光谱特性与水稻生物参数关系的支持下 ,以吉林省德惠市夏家店镇为研究区 ,探讨了一条基于 TM遥感影像反演得到的归一化植被指数 (NDVI)与地面观测数据叶面积指数(LAI)的水稻生长状况的研究途径 ,并利用 NDVI和 LAI对该区 2 0 0 0年和 2 0 0 1年的水稻生长状况进行了分析研究。

In this paper the relation of the reflected spectrum and biologic parameter of paddy is analysised, and with it a method of research on the growth status of paddy using TM remote sensing image is put forward. Xiajiadian town of Jilin province is the researchful section. We analysis the growth status of paddy in 2000 and 2001 using the 'NDVI' and 'LAI'. The result suggests that there is a strong relation between LAI and biomass of paddy, and a strong relation between NDVI and LAI on spectrum. So we can use TM remote sensing image to inspect the growth status of paddy through the relation of NDVI, LAI and biomass.
