土壤水分特征曲线土壤水分特征曲线soil moisture characteristic curve turang shuifen tezheng quxian土壤水分特征曲线(5011 moisture ehar.aeteristie eurve)土壤水分的基质势与含水率的关系曲线，也称土壤水分保持曲线。它是1939年英国土壤物理学家查尔兹(E. C. Childs)在第一次国际土壤学会上建议命名的。绘制此曲线以吸力表示基质势的负值。 土壤水分特征曲线可间接地反映土壤中不同孔隙的孔隙容积，由此可以计算对植物生长有利孔隙的分布情况。该曲线可以分析各种土壤的持水性与土壤水的有效性。利用土壤水分特征曲线可进行土壤水分能量(基质势)与数量(含水率)间的换算。在田间用负压计监测土壤吸力，利用土壤水分特征曲线，即可了解土壤墒情。该曲线还可用于灌溉与排水的管理。由水分特征曲线的斜率得出的容水度，也是分析土壤水分运动所需要的参数。- 含水率与吸力的关系当土壤处于饱和状态，土壤水吸力为零时，对土壤施加一微弱的吸力，土壤中无水流出;当吸力增加至超过某一临界吸力Sa值时，土壤中大孔隙开始排水，含水率开始减少(见图)。临界吸力，也称进气吸力或进气值。沙质土壤有较明显的进气值。当吸力继续提高至大于更多较小孔隙内的吸持力时，较小孔隙中的水分便排除出来。因此，土壤水分特征曲线就是土壤含水率随吸力的提高(即基质势的降低)而减少的关系曲线，此曲线也表明了土壤中土壤水能量和数量之间的相互关系。亘‘5。…l{臀番‘00}{\细，\。一_11\丫 50卜\沙、、、I0 .1 0.2 0.3 0.4 体积含水率e0 .5 0.6土壤水分特征曲线土壤水分特征曲线的形状它受多种因素影响。首先，受土壤质地的影响。沙质土壤孔隙较大，施加较小的吸力就能从土壤中排出水分。大孔隙排空后，仅有少量的水存留在土壤中。粘质土壤，孔径分布较均匀，以薄膜的形式吸附的水分多，要施加很大的吸力才能从土壤中排出水分。其次，受温度变化的影响，当温度升高时，水的粘滞性和表面张力下降，吸力降低。温度对不同土壤和同一土壤在不同含水范围的影响不同。土壤水分特征曲线还和土壤中水分的变化过程有密切关系。此外，土壤水分特征曲线还受土壤的结构和密度，矿物成分，有机质含量，水分中的化学成分等其他因素的影响。 土壤水分特征曲线的测定在室内用张力计(负压计)法或砂性漏斗法均可测得低吸力下扰动或原状土样的水分特征曲线。还可用水汽压平衡法和离心机法等施测。在田间，若在地下水位稳定、无植物生长的地面上，防止蒸发，待自然平衡后，土壤剖面上水分分布曲线即是局部的水分特征曲线。
