辽西山地不同坡向及方位小气候资源研究

目的]研究山地小气候条件，充分利用山地小气候资源，为合理开发辽西丘陵山区，促进农林牧及特色农业综合发展提供依据。方法]根据小气候观测原理，在山地各个坡向、方位设置气象仪器，采用平行观测获取气象要素资料。结果]山地最高温度出现在西坡，最低温度出现在东坡山麓，迎风坡与山顶风速最大，蒸发量与风速关系明显，北坡及山麓土壤湿度最好。结论] 阳坡热量条件好，可种植生育期较长的作物和瓜果类等；北坡土壤湿度好可植树造林增加地面植物；西坡、山麓要注意高温、低温霜害等不利因素。

Research on Microclimatic Resources of Different Slope Aspect in Liaoxi Mountain

Objective] The study aimed to research the microclimatic conditions of the mountain,and take full advantage of mountain microclimate resources,and provide the basis for reasonably developing Liaoxi hilly area,promoting the development of forestry,animal husbandry and characteristic agriculture.Methods] According to the principle of micro-climate observation,in the various slope aspects of mountain,meteorological factor data was obtained by using parallel observation.Results] The highest temperature appeared in the western slope,the lowest temperature appeared in the east slope of foothills,the wind speed of windward slope and the mountain peak was biggest,the relationship of evaporation and wind speed was significant,soil moisture of northern slope and foothills was best.Conclusion] Heat condition of sunny slope was good where could plant long period crop and fruits,the soil moisture of northern slope was better where could plant plants which increased ground,western slope and foothills should pay attention to high temperature,low temperature and other unfavorable factors.
