In practices,measuring leaf area index(LAI)in large area scale is very difficult.
实践中,大尺度上测量叶面积指数(LAI)很难实现,利用遥感技术进行LAI的定量反演成为当前研究的重点。

基于垂直植被指数的东北黑土区玉米LAI反演模型研究
The correlation analyses between soybean LAI and selected vegetation indices(VIs),including some hyperspectral vegetation indices based on waveform analysis of the reflectance across the vegetation red edge were carried out,and the performance of the VIs was evaluated on the basis of their capability to accurately estimate LAI in the paper.
对于全部植被指数和窄波段植被指数而言,一阶微分绿度植被指数1DZ-DGVI对大豆LAI的估算效果最佳;而对于宽波段植被指数而言,以宽波段三角植被指数B-TVI的效果最佳。
Soybean LAI Estimation with in-situ Collected Hyperspectral Data Based on BP-Neural Networks;
方法实测不同水肥耦合作用下,大豆冠层的高光谱反射率与叶面积指数(LeafAreaIndex)数据,对二者进行相关分析;采用敏感波段(801nm,670nm)构建RVI,NDVI,SAVI,OSAVI和MTVI2植被指数,建立大豆LAI估算模型;最后采用相关系数较大的波段作为神经网络模型的输入变量进行大豆LAI的估算。
