| 摘 要： | 文章以内蒙古东胜区泊江海镇覆沙地3种配置模式沙柳林为研究对象,在典型样地内采取样株法,采用SPSS、EXCEL等统计软件对数据进行回归分析,建立沙柳灌丛生物量与各测树因子的回归模型得出:沙柳冠幅直径、灌丛高度的组合和萌条数与生物量的相关性较高。低密度、中密度沙柳纯林和柠条沙柳混交林内沙柳灌丛地上生物量最优模型依次为:w=13.612-4.778(D2H)+0.748(D2H)2、w=1.408×e(0.027N)和w=-0.468+0.236N-0.001N2。用复相关系数、样本均方、均方比对模型进行评价、优化和适合性检验,拟合效果均较好。

| Abstract: | This article studies on salix psammophila forest configured with three Allocation models in the cover sand of Bojianghai town,Ordos,Inner Mongolia.Through the method of taking samples in the typical sample yard,The relationship between biomass and test trees factors was made.The result shows that: Biomass has a great influence on sprout numbers and the combination of salix psammophila crown diameter and shrub height.The best model of salix psammophila upground biomass with low density,mid-density salix psam... |
