摘要
本文运用石竹产区内 30块固定标准地的调查材料 ,配制竹林密度效应模型 W=0 .0 4 192 347N1.2 0 684 1D1.83 3 92 5复相关指数 R=0 .96 ,F检验值为 141。偏相关系数 R1=0 .86 ,R2 =0 .98。检验结果达到极显著相关 ,对该模型进行生产弹性分析 ,边际产量分析 ,为调整竹林密度提供科学依据。
Based on the investigation data of 30 plots of Phyllostachys nuda, density effect model of Phyllostachys nuda was built, it:W=0.04192347N 1.206841 D 1.833925 ,R=0.96,F=141,R 1=0.86, R 2=0.88. Through testing, it showed model was extremely significant. it would provide a scientific basis for their correlationship of management and density adjustment Phyllostachys nuda stand
