云开大山冬季热量资源利用

THE UTILIZATION OF HEAT RESOURCES OF THE YUNKAIDA MOUNTAIN IN WINTER

云开大山位于南亚热带南缘,种植亚热带作物热量有余,种热带作物常常不能安全越冬。为了合理利用地形环境,本文分析了山地环境避寒原理,给出了平流型寒害的综合表达指标,根据不同地形环境,提出了作物合理种植的建议。

The Yunkaida Mountain located in the southern fringe of the south sub-tropic zone. There has heat resources more enough to plant subtropic crops. But the tropic crops would not adapt in winter. In order to rationally use the different topographic environmeut, based on analysis of the cold prevention principle of mountain environment, the author suggests the synthe tical indexes of the cold injury. The advective cold injury indexes expressionis: TS= The indexes expression of radiant frost damage is-Tm = 3.5-1.6 log NAccording to the different topography environment, the anthor advanced some suggections to rationally planting the crops.
