摘  要：
采用水量平衡的方法研究了火地塘林区混交林对降雨的再分配状况。研究结果表明 ,7— 10月份 ,试验区内林冠截留量 12 6 .5 8mm,树干茎流量 11.6 9mm,透过雨量 5 88.2 mm,分别占同期降雨总量的17.43% ,1.6 1%和 80 .96 % ,大部分降水以林内雨的形式进入林下 ;枯落物截留水量 85 .0 1mm,占同期降雨总量的 11.75 % ,在蓄留降水方面有着重要的作用 ;林地土壤蓄水量变幅为 5 3.45 mm,对削减洪峰流量、调节河川径流、缩短枯水期有重要意义 ;在林分水量平衡中 ,蒸发散量为 5 2 1.0 1mm,径流总量为 15 5 .2 4mm,土壤贮水量变化量为 + 5 0 .0 9mm,分别占同期降雨总量 72 6 .34mm的 71.73% ,2 1.37%和 6 .9% ,蒸发散是森林生态系统水分输出中最重要的一项

摘  要：
Used the method of water balance, the redistribution of rainfall by mixed forest in Huoditang area of Qinling mountain is studied. The results are as follows: (1) Woods canopy's interception of rainfall, runoff of woods stems and the rainfall under the woods are 126.58, 11.69 and 588.2 mm, which account for 17.43, 11.61 and 80.96 percent of the total rainfall respectively during July to October in experimental area. Most of precipitation falls into forest by the rainfall under woods. (2) Dead leaves and branches under the woods intercept 85.01 mm rainfall, which account for 11.75 percent of the total rainfall. They play important roles in retaining water. (3) Changing amplitude of water storage in woodland is 53.45 mm. Woodland is very important for reducing the crest of runoff, adjusting runoff and shortening dry season. (4) The results of forest eco system water balance are that forest evapotranspiration is 521.01 mm, the runoff is 155.24 mm, and the change of woodland soil water storage is +50.09 mm. They make up 71.73, 21.37 and 6.9 percent of the total rainfall, 726.34 mm of the same period. Forest evaportranspiration is the most part of woods water output.
