摘　　要：通过测定妃子笑荔枝叶片的实际面积(S)、叶长(a)和叶宽(b),经过矫正系数(叶片实际面积与叶长、叶宽乘积的比值)的计算和线性回归分析,构建了妃子笑荔枝叶片面积估算公式:S=0.65ab,S=0.6488ab+0.0018。验证结果表明,上述2个公式均能准确地估算出妃子笑荔枝的叶片面积。The true area （S） ,length （a） and width （b） of leaves of lychee Feizixiao were determined,and the corrected coefficients （ the ratio of the true area to the product of the length and width of leaves） were calculated and analyzed in linear regression,based on which two formulas （ S = 0. 65ab and S = 0. 648 8ab＋0. 001 8 were established to estimate the leaf area. The verification of these two formulas indicated that they both can be used for accurately estimating the area of the leaves of lychee Feizixiao through measuring the length and width of leaves.
