摘要
应用数量化理论I原理,选择立竹度、抚育措施等13个影响出笋的因素,设立并调查60个样地的出笋量,以这13个因素作为项目,出笋量作为因变量建立台湾桂竹林出笋量的预测模型。复相关系数t检验呈极显著水平,标准误差率E检验为13.1%,达到精度要求,这个模型可用于台湾桂竹林的出笋量预测。偏相关系数t检验表明竹林结构、立地条件、抚育措施、大小年等对台湾桂竹林的出笋量均有明显的影响。
A prediction model for the shoot yield of Phyllostachys makinoi Hayata
wasestablished based on the data of shoot yield of the sample plots. The principles of
quantitativetheory I was adopted to analyze 1 3 factors which had influence on the shoot yield
such asculm density, silvicultural operations etc.The complex correlation coefficient t test is
ex-tremely significant,with the result of standard error rate E test being 13.1%,reaching
theprecision prescribed. The establisbed model can be used to predict the bamboo shoot yield
ofPh.makinoi. Furthermore,the results of partial correlation coefficient t test demonstrate
thatsuch factors as bamboo stand structure,site condition,cultural operations,and bumper or on-
off year etc, have apparent influence on the shoot yield of Ph.makinoi.
