【摘要】 浙江省淳安县千岛湖由于有广阔的水面和经封山育林30年恢复的森林植被,形成的小气候效应十分明显。本文探讨了小气候条件:热量和水分因子,小气候效应和林木生长发育的关系。说明该地区的降水量充沛,热量资源丰富,具有冬暖夏凉的小气候特征,从而延长了林木的生长期,减轻了冻害和旱害,促进了林木的生长,为一些树种的北移创造了小气候条件。更多还原

【Abstract】 The microclimatic efficiency of wide water area and regenerated forest vegetation in Qiandao Lake’s region was obvious. This article discussed the influences of microclimate, heat and water factors on the tree growth. The results proved that in this region the rainfall and heat resource all year were favourable to prolong the growing seasons, to decrease the freezing and dry hazards, to increase the growth rate, and to make up a good microclimate for introduction of many exotic tree species.更多还原
