摘 要: | [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。

Abstract: | [Objective] The aim was to study the regression relationship between water index(WI) and water content(FMC) of different growth periods of sawtooth oaks leaf.[Method] Taking sawtooth oaks in Huaguo Mountain,Lianyungang City as research object,the sensitivity of WI to leaf FMC was studied at leaf level,and statistical characteristics were analyzed.[Result] The WI of sawtooth oaks leaves was sensitive to the changes of FMC,and the line regression level between them was significant.A fitting curve between leaf FMC and WI was obtained.[Conclusion] The research provides reference for acquisition methods of vegetation water remote sensing within the range of study area. |
