在南平市王台乡典型中心抽取3个村为一级样本;在一级样本中,随机抽取50户农户为二级样本,进行薪材消耗量及其有关因子的调查。应用多元统计方法,建立了薪材消耗量与9个因子间的数量化线性混合模型;复相关系数为0.926,各因子对薪材消耗量的偏相关系数分别为0.325、0.151、0.752、0.603、0.152、0.209、0.630、0.110、0.154,复相关系数t检验达极显著水平,有4个因子的偏相关系数达极显著或显著水平。
Three villages were selected as the first-level samples in the typical center of Wangtai Township, Nanping City. In the first-level samples, 50 households were randomly selected as the second-level samples for fuelwood consumption and related factors. The multivariate statistical method was used to establish a quantitative linear mixed model of fuelwood consumption and nine factors. The complex correlation coefficient was 0.926. The partial correlation coefficients of each factor to the fuelwood consumption were 0.325,0.151,0.752,0.603 respectively, 0.152,0.209,0.630,0.110,0.154, the t-test of correlation coefficient reached the extremely significant level, and the partial correlation coefficients of four factors reached extremely significant or significant level.
