摘要
以大埠乡喀斯特区典型5种树种作为实验对象,通过处理高光谱数据,分析植物叶片光谱与含水量的相关关系,找到叶片含水量的最优波段组合及其光谱指数。基于植物叶片光谱,遍历400~2 500 nm区间内所有的植被指数对喀斯特区典型植被含水量进行反演,效果较为理想。实验结果为喀斯特区域植被叶片含水量反演精度的提高提供了重要的参考价值。
In this paper,taking five typical species of Karst area in Dabu Township as the experimental objects,through the processing of hyperspectral data,we analyzed the correlation between plant blade spectrum and water content,and found the optimal band combination and spectral index of blade water content.Based on the plant blade spectrum,we used all the vegetation indices in the interval of 400~2500 nm to invert the typical vegetation water content in Karst area.The effect was ideal,which could provide an important reference value for the improvement of vegetation water content inversion in Karst area.
