[Objective] The aim was to study the regression relationship between water index (WI) and water content (FWC) 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 FWC was studied at leaf level, and statistical characteristics were analyzed. [Result] The WI of sawtooth oaks leaves was sensitive to the changes of FWC, and the line regression level between them was significant. A fitting curve between leaf FWC and WI was obtained. [Conclusion] The research provides reference for acquisition methods of vegetation water remote sensing within the range of study area.
