| 摘 要： | 以北京地区冬小麦为研究对象，利用TM传感器的光谱响应函数处理地面测量获得的冬小麦冠层光谱数据，得到对应于TM传感
器红光波段和近红外波段的反射率，进而计算出冬小麦冠层的归一化植被指数NDVI。建立了LAI与NDVI之间的不同经验关
系模型，对实验结果进行分析后得出，LAI与NDVI之间具有高度的指数相关性。

| Abstract: | Fundamental knowledge is necessary for establishing a statistical model between LAI and vegetable indices to perform the inversion of LAI with remotely sensed data.The authors processed the canopy spectral data of winter wheat in Beijing area obtained by ASD Spectrometer with spectral response function of the TM sensor,and got the canopy NDVI of the wheat.Two different kinds of non-linear statistical data of LAI and NDVI were constructed in this paper.The experimental results show that there exists a close exponent correlation between LAI and NDVI. |
