From april to october of 2001 , a 31 - year - old pinus tabulaeformis and quercus variabilis mixed stand was studied on forestland evapotranspiration and water balance in western mountainous area of beijing
摘要2001年4 - 10月，对北京西山地区一块31年生的油松、栓皮栎混交林的林地蒸散和水量平衡进行了研究。
The water consumption of transpiration of pinus tabulaeformis and quercus variabilis mixed stand has marked seasonal difference , and the standard specific conductivity of quercus variabilis in the growing season is 2 . 6 times as high as that of pinus tabulaeformis
油松和栓皮栎混交林的蒸腾耗水表现出明显的季节差异，栓皮栎的生长季标准比导率明显高于油松，是油松的2 . 6倍。
