为揭示樟子松人工林水量平衡规律,在辽宁省章古台地区,选择林龄为32 a、密度为404株/hm2的樟子松人工林,利用2 a(2010、2011)的观测结果,采用水量平衡方法对樟子松人工林的降水分配进行研究。结果表明:樟子松人工林内降水量、树干茎流量、林冠截留量分别为422.7、0.8、28.1 mm,占同期降水量的93.6%、0.2%、6.2%。樟子松蒸腾耗水量、枯落物+林下植被+土壤蒸散量、土壤贮水量变化量分别为116.1、287.3、20.1 mm,占同期降水量的25.7%、63.6%、4.5%;樟子松蒸腾耗水量占林地内蒸散量的28.8%,枯落物+林下植被+土壤蒸散量占林地内蒸散量的71.2%。
為揭示樟子鬆人工林水量平衡規律,在遼寧省章古檯地區,選擇林齡為32 a、密度為404株/hm2的樟子鬆人工林,利用2 a(2010、2011)的觀測結果,採用水量平衡方法對樟子鬆人工林的降水分配進行研究。結果錶明:樟子鬆人工林內降水量、樹榦莖流量、林冠截留量分彆為422.7、0.8、28.1 mm,佔同期降水量的93.6%、0.2%、6.2%。樟子鬆蒸騰耗水量、枯落物+林下植被+土壤蒸散量、土壤貯水量變化量分彆為116.1、287.3、20.1 mm,佔同期降水量的25.7%、63.6%、4.5%;樟子鬆蒸騰耗水量佔林地內蒸散量的28.8%,枯落物+林下植被+土壤蒸散量佔林地內蒸散量的71.2%。

To uncover the water balance law of Pinus sylvestris var.mongolica planted forest in Zhanggutai area in Liaoning province, and to provide scientific direction for the management,based on the data and information collected from 2010 and 2011,the precipitation distribution and evapotranspiration of the ecosystem were studied in 32 years old (and 404 plants per ha.) planted forest by using the method of water-balance.The results showed: the gross of throughfall, stemflow, and the canopy interception was 422.7mm,0.8mm, 28.1mm separately, the proportionment compare to the gross of annual precipitation(451.5ram)was 93.6%,0.2%,6.2%.The crown transpiration,Liter+ Understory vegetation+Soil evapotranspiration (LUS), and soil water storage were 116. 1mm, 287.3mm,20. lmm separately, the proportionment compare to the gross of annual precipitation(451.5mm) was 25.7%,63.6%,4.5%.he crown transpiration was 28.8% of evapotranspiration of forest land,and LUS was 71.2%.
