于2012年5月中旬至10月初,在大兴安岭干旱阳坡的蒙古栎林内,选择不同的坡向和坡位设置观测样地定点测定土壤温度、空气温湿度和土壤含水量。分析结果表明:不同坡向土壤温度由大到小为南坡、西南坡、东南坡,气温由大到小为西南坡、南坡、东南坡,空气湿度和土壤含水量由大到小均为东南坡、西南坡、南坡;南坡空气和土壤温度由大到小为坡上、坡下,土壤含水量坡下大于坡上含水量,空气湿度坡上大于坡下湿度;空气和土壤温湿度受空间位置和季节分布影响差异较大,不同坡向和坡位土壤温湿度差异明显,不同季节空气温湿度波动较大。
于2012年5月中旬至10月初,在大興安嶺榦旱暘坡的矇古櫟林內,選擇不同的坡嚮和坡位設置觀測樣地定點測定土壤溫度、空氣溫濕度和土壤含水量。分析結果錶明:不同坡嚮土壤溫度由大到小為南坡、西南坡、東南坡,氣溫由大到小為西南坡、南坡、東南坡,空氣濕度和土壤含水量由大到小均為東南坡、西南坡、南坡;南坡空氣和土壤溫度由大到小為坡上、坡下,土壤含水量坡下大于坡上含水量,空氣濕度坡上大于坡下濕度;空氣和土壤溫濕度受空間位置和季節分佈影響差異較大,不同坡嚮和坡位土壤溫濕度差異明顯,不同季節空氣溫濕度波動較大。

For the characteristic of the arid sunny-slope Mongolian oak forests temperature and humidity in Daxing ’ an Mountains, we selected different slope aspect and slope position set observation sample plots and fixed point to measure soil temperature, air temperature, humidity and soil moisture from mid May to early October in 2012.The soil temperature of different slope aspect was in the descending order of southern slope, southwest slope and southeast slope, air temperature was in the descending order of southwest slope, south slope, and southeast slope, and air humidity and soil moisture con-tent was in the descending order of southeast slope, southwest slope and south slope.The southern slope air and soil tem-perature were in the descending order of upper slope, lower slope, soil moisture was in the descending order of lower slope and upper slope, air humidity was in the descending order of upper slope and lower slope.Air and soil temperature and hu-midity were affected significantly by spatial distribution and seasonal differences, and soil temperature and humidity were with a clear difference in different slope direction and slope position with large fluctuation in different seasons.
