| 摘 要： | 根据黄土地区的防护林生态系统水分循环的特征，提出了防护林生态系统水量平衡方程，通过对１９８８￣１９９２年刺槐、油松、沙棘、虎榛子林地、草地和裸地６种生态系统水量平衡的分析，结果表明降雨是防护林生态系统主要的水分输入量，刺槐和油松林根际层以下土壤水分的上升补给，也是重要的水分输入项，特别是春季的４￣６月份，更是防护林生态系统极为重要的水分来源，刺槐林和油松林平均根际区下层土壤水分上升补给量占降雨量的

| Abstract: | According to the features of water cycle in protective forest ecosystem in loess area,the equation of water balance for the protective forestry ecosystem was put forward.The tables of water balance were presented for 6 ecosystems in the period from 1988 to 1992.From the experimental results of water balance,the input and output of the protective forest ecosystem were analyzed.It is pointed out that rainfall and exchange of water between root zone and deep soil were main water input,evapotranspiration and ca... |
