摘要
本文应用空气动力学原理,统计学和气候学方法,对三江平原次生柞木林不同群落结构林分的小气候因子的变化规律做了定位观测和研究,并在此基础上对效应带产生的气候学效应进行了综合分析。结果表明,效应带的开拓改变了近地面层乱流、湍流交换系数,增加了热散射通量,从而促使小气候因子重新分配,并产生了明显效应,特别是在生长旺季的6、7月份。
Location observations were carried out variation of climate factors in secondary Oak forest stands of different community structures in Sanjiang Plain by aerodynamics theory,statistic and climatology method in the paper. Furthermore, climatic effects made by effect-belt were analysed synthetically. The results are as follows:The index of confused and turbulent flow were changed by extension of effect-belt. This increased scattering flux of heat,made microclimate factors re-distributed, and get significant effects especially in June and July.
