| 摘 要： | 选择江苏省连云港市花果山优势树种麻栎树为研究对象,采集其位于不同海拔位置的树木叶片,测量鲜重及经不同程度阴干处于不同水分状态下叶片的水分指数(W I)和含水率(FMC),在叶片水平上,研究水分指数与含水率之间的关系。研究表明,水分指数对麻栎叶片含水率的变化敏感,二者之间统计关系明显;叶片含水率可以通过水分指数进行曲线拟合,拟合曲线为y=19.022x2-32.707x+14.064,其稳定性较好。

| 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. |
