摘　　要：对齐齐哈尔(沙壤土区)、杜蒙(风沙土区)、青冈(黑土区)等3个代表黑龙江省半干旱区典型地点防护林区内7、8、9月主要气象因子(气温、气湿、风速、降雨量等)及土壤入渗率情况进行了定期观测,结果表明:3个月份平均气温杜蒙>齐齐哈尔>青冈,气湿为青冈>齐齐哈尔>杜蒙,风速为杜蒙>齐齐哈尔>青冈,土壤入渗率为杜蒙>齐齐哈尔>青冈,揭示了黑龙江省半干旱区防护林内不同土壤类型之间主要气象因子的变化特征及规律,为半干旱区防护林功能评价提供了重要依据。Main meteorological factors （air temperature, air humidity, wind speed, rainfall, etc. ） and soil infiltration rate in July, August ＆ September in three typical locations which representative semiarid shelterbehs in Heilongjiang Province - Qiqihar （sandy loam district） , Durbote Mongolian Autonomous County （Sandificational） Qinggang （black soil area） were periodically observed. Result shows that ： in these three months, the sequence of the average temperature is Durbote Mongolian Autonomous County〉 Qiqihar〉 Qinggang;the sequence of the air humidity is Qinggang 〉 Qiqihar〉 Durbote Mongolian Autonomous County;the sequence of the wind speed is Durbote Mongolian Autonomous County 〉 Qiqihar〉 Qinggang;the sequence of the soil infiltration rate is Durbote Mongolian Autonomous County 〉 Qiqihar〉 Qinggang . It reveals the varied characteristics ＆ laws of the main meteorological factors among different soil types in the shelterbelt zone. It provides important basis on evaluating shelterbelt in semiarid area.
