摘　　要：以云南省和四川省交界的泸沽湖生长的波叶海菜花为研究对象,于2012年9月至2013年3月分别利用等级法结合杭州万深LA-S叶面积指数分析系统和等级法结合量测法,对不同居群的波叶海菜花的叶面积进行了测定,并计算出叶面积指数,用SPSS 13.0分析和处理试验数据,研究了不同海菜花居群叶面积指数的标准误差、标准差、方差和变异系数等。结果表明:所测叶面积指数(LAI)具有中等变异性,不同居群的波叶海菜花的叶面积指数不同,分别为落水村(2.66)>三家村(2.42)>山垮村(2.12)>木垮村(1.83)>里格村(1.17)。该研究有助于对水生植物测量叶面积指数的方法选择提供参考。Taking Ottelia acuminate var. crispa that growing in the Lugu Lake bordering Yunnan and Sichuan as research object,using a combined way of classification and Hanzhou Wanshen LA-S Leaf-Area Index Analysis System, another combined way of gradation and mensuration from September 2012 to March 2013,the LAI of different Ottelia acurninata （Gagnep.） populations were measured and calculated. And the data were dealt with SPSS 13. 0,the standard errors, standard deviation,variances and variation coefficients of the different populations were studied. The result showed that the measured LAI had medium variability, LAI of different Ottelia acuminate var. crispa populations in different village were different,respectively.Luoshui 2. 66）〉Sanjia（2. 42）〉Shankua（2. 12）〉Mukua（1.83）〉Lige（1.17）. This study was also a helpful alternative to measure the leaf area of aquatic plants ; these may provide the foundation of method selection for LAI determination of aquatic plant.
