The Relationship between Sawtooth Oak Leave WI and FMC

Abstract

Abstract: Sawtooth oak,a dominant species,was chosen as the study object in Huaguo Mountains of Lianyungang City in Jiangsu province.Leaves of Sawtooth oaks growing at different elevation locations were picked up as samples.Leave water index(WI) and water content(FMC) in fresh and different water states by shade drying were surveyed.The statistic characteristics between WI and FMC were studied.The results showed that the WI of Sawtooth oak leaves is sensitive to the changes of FMC.Leave FMC could be deduced by fitted curve using WI.The fitted curve is y=19.022x²-32.707x + 14.064,and its precision is high.

Key words: high spectral remote sensing, water index, water content, regression analysis, sawtooth oak leaf
