摘要
本文对广西毛竹两个主产区(桂林地区、柳州地区)15个县的9项气象因子,应用多元统计分析中的主成分分析法、逐步回归分析法进行分析,结果表明:影响广西毛竹分布、毛竹生长的气象因子主要是年均温、≥10℃积温、年极端最高温度、相对湿度、发笋期雨量、年雨量。
Fine meteorological factors of 15 counties in the major bamboo producer areas of Guangxi Province were analyzed by principal component analysis and by means of the multivariate regression analysis of a multiple statistic method. The results indicated that the most important meteorological factors affecting bamboo, distribution and growth were the year's average temperature, ≥10℃, accumulated temperature, the highest annual temperature of many years, relative humidity, rainfall amount in the bamboo-shoot sprouting period, and yearly rainfall.
