【摘要】 为揭示黄土高原中心地带子午岭林区生态气候效应特征,利用子午岭林区太白镇气象站气候资料和周边非林地华池县和庆城县气象站同步观测资料,分析月气象要素的年变化曲线和资料序列方差的统计检验结果表明:子午岭林区各月平均气温明显低于周边地区,林地5、7、9月降水量及4-9月降水时间和空气湿度明显多(大)于周边地区,林地盛夏(6-8月)月平均蒸发量明显偏小,表征黄土高原子午岭林地的生态气候效应具有明显的冷凉、湿润和水分利用率高的特征。更多还原

【Abstract】 In order to explore the characteristics of ecoclimate effects, the annual variation of meteorological factor was analyzed by using the meteorological data from Taibai Weather Station which located in Ziwuling forest region, Huachi Weather Station and Qingcheng Weather Station which located in the boarder of forest area. The result showed that the temperature and evaporation in Ziwuling forest region in each month were obviously lower, and meanwhile, the precipitation in May, July and September and air humidity from April to September were higher than that in the surrounding area. The rain days in forest region were more than that in the surrounding area. It means that the climate in Ziwuling forest region was cold and humid.更多还原
