应用灰色系统理论的关联度分析法,探讨高丘低山毛竹林各生长期气象因子与毛竹生长量的关联程度。结果表明:影响新竹数量、新竹平均眉围和新竹产量(重量)的主要气象因子分别是:越冬期降水天数和秆形生长盛期积温、越冬期地下积温、秆形生长末期日照时数。同时认为,越冬期是高丘低山毛竹林竹笋地下生长的重要阶段。这一时期均匀降水和林地保温对提高成竹数量和平均眉围水平有不容忽视的作用。
Using the gray system theory, the correlation analysis method was used to explore the correlation between meteorological factors and the growth of Phyllostachys heterocycla cv. The results showed that the main meteorological factors influencing the quantity of Hsinchu, the average eyebrow circumference of Hsinchu and the yield (weight) of Hsinchu were as follows: the number of precipitation days in wintering period and accumulated temperature in culm growth stage, accumulated temperature in wintering period, sunshine hours at the end of culm growth. At the same time, it is considered that the overwintering period is an important stage for underground growth of bamboo shoots in Moso bamboo forest. During this period uniform rainfall and woodland insulation to improve the number of bamboo and average brow level can not be ignored.
