| 摘 要： | 选择16个与毛竹生长、分布有关的气候因子对湖北省76县（市）进行主成分分析,结果表明：前4个主成分的累计贡献率达83.25%.以其中的年降水量、年积温、年蒸发量、7月温度、4-10月降水量、年均温度、1月温度、纬度8个因子为主导因子,构建各样品（县市）的得分方程,绘制散点图.根据散点的群聚性,结合毛竹在湖北省的生长分布现状以及与行政区划的一致性,按照毛竹水平区划的全国标准,通过R型最短距离聚类法将湖北省分为：毛竹最适宜区Ⅰ、毛竹适宜区Ⅱ、毛竹较适宜区Ⅲ、毛竹零星分布区Ⅳ、高山毛竹引种区Ⅴ. |

| Abstract: | Principal Component Analysis （PCA） was applied to analyze the correlations among the growth and distribution of Phyllostachys edulis and 16 climatic factors in 76 counties or municipalities of Hubei Province. The results are as follows： The accumulated contribution rate of the leading four principal components reached 83.25%. The scoring equation of each sample, i. e. , each of the 76 counties or municipalities was built by taking eight factors including annual precipitation, annually accumulated effective temperature, yearly evaporation, the average temperature in July, the rainfall between April and October, the yearly average temperature, the mean temperature in January and latitude as the leading factors. Five zones were classified by clustering analysis method with R type shortest distance for P. edulis cultivation according to the clustering characteristics of the scattered points, the national standards of horizontal regionalization for P. edulis, integrated with the consistency between the growth, distribution situation of P. edulis and jurisdiction division in Hubei province. The five zones were the optimum area Ⅰ ; the suitable area Ⅱ; comparatively suitable area Ⅲ, sporadic distribution area Ⅳ, and the alpine introduction area Ⅴ. |
