摘　　要：以华北落叶松桦木混交林、山杨桦木混交林和油松蒙古栎混交林为研究对象,分别对其6~9月间的土壤含水量动态变化实时监测,结果表明：华北落叶松桦木混交林、山杨桦木混交林和油松蒙古栎混交林土壤含水量变动范围分别为5.67%~15.43%、7.10%~24.23%、2.25%~14.57%,土壤水分调节层分别在50cm、20cm、30cm,土壤蒸发总量分别为43.1cm、38.1cm、50.2cm;3种林地7月份土壤蒸发量最大,导致土壤含水量最低。The Larix principis-rupprechtii and Betula spp.,the Populus davidiana and Betulaspp.mix-forest,the Pinus tabulae formis and Quercus mongolia mix-forest were used as the research object,and their dynamic changes of soil moisture content were monitored respectively during June to September.The results showed that for the Larix principis-rupprechtii and Betula mix-forest,the Populus davidiana and Betulaspp.mix-forest,the Pinus tabulaeformis and Quercus mongolia mix-forest,their moisture contents in soil were5.67%to 15.43%,7.10%to 24.23% and 2.25%to 14.57%;the soil moisture adjustment layer were 50 cm,20cm,30 cm respectively;total soil evaporation were 43.1cm,38.1cm,50.2cm respectively.The three types of woodland had the largest soil evaporation in July,leading to the lowest soil moisture content.
