[目的]研究不同生长期麻栎叶片水分含量(FMC)与水分指数(WI)的回归关系。[方法]以连云港市花果山麻栎树为研究对象,在叶片水平上研究了WI对叶片FMC变化的敏感性,并分析其统计特征。[结果]WI对麻栎叶片FMC变化敏感,二者线性回归水平显著,并得到FMC与WI之间的拟合曲线。[结论]该研究为研究区范围内植被水分遥感获取方法提供了参考。
[Objective] The research aimed to study the regression relationship between moisture content (FMC) and moisture index (WI) in different growth stages of Quercus variabilis. [Method] With the study of the Alpine oak tree in Huaguoshan of Lianyungang City, the sensitivity of WI to the change of leaf FMCs was studied at leaf level and its statistical characteristics were analyzed. [Result] The results showed that WI was sensitive to the change of FMC in leaves of Quercus acutissima, the linear regression was significant and the fitting curve between FMC and WI was obtained. [Conclusion] The study provided a reference for the remote sensing acquisition of vegetation moisture in the study area.
