摘  要：
云南松、华山松、川滇桤木、圆柏、蓝桉等5个树种在昆明寻甸羊街相同立地条件下生长适应性研究结果表明,各树种间生长均存在极显著差异,川滇桤木造林成活率和生长量明显优于其它4个树种,具有较强适应能力,其树高、地径、冠幅等3个生长性状具有较高的一致性,并超过了兰桉、云南松、华山松的各项指标低于川滇桤木,但其地径、冠幅生长性状均高于兰桉,表现出了良好适应性。运用非线性回归分析,建立5个树种的树高和地径的曲线模型,模型拟合性好,相关指数的平方(R2)均在0.98以上,反映出5个树种4 a生的生长规律,为当地造林树种的筛选提供依据和参考。

摘  要：
The experiment on the growth adaptability of five tree afforestation species namely pinus vunnanensis,pinus armandi,alnus ferdinandi-coburgii,cupressus duclouxiana,eucalyptus globulus in yangjie of xundian of kunming city indicated the growth and conservation reached significant level among different afforestation species.alnus ferdinandi-coburgii's survival percentage and growth increment was advantage over other 4 species,had good adaptability,three growth indexes,namely tree height,basal diameter,crown width were correlated,and was advantage over eucalyptus globules.that all indices of silviculture of pinus vunnanensis and pinus armandi were lower than alnus ferdinandi-coburgii,but two growth indexes,namely basal diameter,crown width,were all superior to those from eucalyptus globules,showing good adaptability.With Nonlinear Regression Analysis methods,the tree height curve models and basal diameter curve models of five tree species were established.these models have good fittings,the correlation index square(R2)are all over 0.98.This not only reflected the growth rhythm of 4-year-old five tree afforestation species but also provided the theoretical and practical reference to the screening for the afforestation species in the study area.
