中文摘要	黄土丘陵沟壑区水土保持林合理林分密度的确定须遵循量水植树的基本原则。依据水量平衡原理，在无地表径流，无土壤的深层渗漏，降水资源得以充分利用的情况下，林分在某一生长季内对降水资源的消耗量应小于或等于降水总量，根据上述原理分别计算了晋西黄土区蔡家川流域刺槐和油松林的合理林分密度取值。通过观测2002年和2003年生长季时段内林龄为13a不同密度刺槐纯林和林龄为17a不同密度油松纯林林地的土壤含水量动态变化，得到受水分胁迫威胁最小的刺槐、油松林分密度与依据公式计算得出的刺槐和油松林的合理林分密度相一致，说明该文提出的计算方法计算黄土区刺槐和油松的合理林分密度具有较好的适用性，且该方法简单易行，参数获取方便，值得在黄土区进一步推广应用。
英文摘要	Determine the proper stand density of soil and water conservation forest in Loess area should obey on the rule of ＂afforestation amount based on precipitation＂. According to water balance principle,under fully use precipitation and without runoff and soil deeply percolation,the amount of water consumption of stand during growing season should be smaller or equal to precipitation amount. Basis on that principle,the value of proper stand density of Robinia pseudoacacia and Pinus tabulaeformis was calculated in Caijiachuan watershed. Based on the observation data of soil water dynamic changes of 13-old Robinia pseudoacacia with different stand density and 17-old Pinus tabulaeformis with different stand density during growing season in 2002 and 2003 ,the value of stand density with best anti-arid abilities of Robinia pseudoacacia and Pinus tabulaeformis forest was the same as the calculated value of stand density according to the formula. This result show that this formula has good application on calculation the proper stand density in Loess area. Besides, the parameters of this formula are easy to get. Therefore, this method to calculate proper stand density in Loess area should be popularized further more.
