摘要:对额尔齐斯河流域河岸两侧天然分布的4种杨树:欧洲黑杨(Populusnigra)、苦杨(P.laurifolia)、额河杂交杨(P.×jrtyschensis)、银白杨(P.alba)的叶面积指数和比叶面积进行了测定。研究了不同径阶各树种的比叶面积和叶片生物量的关系,以及各树种叶面积指数与其叶片生物量之间的关系,结果表明:1.本试验区内各种杨树的叶面积指数变动范围为0.243~4.463;2.各树种的单株叶面积与其叶生物量均呈正相关直线,模拟方程为y—ax—b,呈线性递增趋势(r^2=0.9178~0.9725);3.各径阶植株的平均比叶面积和叶片生物量在植物种之间差异显著,各树种的比叶面积和叶片生物量均呈显著负相关(P〈0.01)。
Leaf area indite and specific leaf areas of four species poplar species in Ergis basin were measured, namely Populus nigra, P. lauri folia, P. × jrtyschensis and P. alba. Relationship between specific leaf area and the leaf biomass of different diameters as well as the relationship between leaf area index and leaf biomass were examined. The results showed: (1) the variation range of leaf area index was 0. 243 -4. 463 in this area, (2) Linear positive correlationship existed between the individual tree leaf area index and the leaf biomass with an analogue equation y = ax-b, and exhibited a linear increasing pattern(r^2= 0. 917 8-0. 972 5) ; (3) differences in average specific leaf area and leaf biomass of all diameter classes were significant among all kinds of poplars, specific leaf area and leaf biomass of all kinds of poplars assumed the remarkable inverse relation(p〈0.01).
