采用直接测定法对秦岭火地塘林区２种针叶林分和３种阔叶林分的水源涵养和理水效能进行了研究，结果表明：不同林分类型间水源涵养和理水效能具有明显差异，阔叶林比针叶林能显著地增加土壤水分收入，减少水分消耗；推迟径流时间，延长径流过程，削减洪峰流量；在降水较少时期增加河流水量，促使雨水均匀进入河流的作用更加突出，显示了较强的水源涵养和理水作用。
The water conservation and water management efficiency of two kinds of coniferous forest and three kinds of broad-leaved forest in Huoditang area of Qinling Mountains were studied by direct determination method. The results showed that: the water conservation and water management efficiency of different types of forest had Significantly different, coniferous forest broad-leaved forest can significantly increase soil water income and reduce water consumption; delayed runoff, extend the runoff process and reduce peak flow; in less precipitation, increasing the amount of water to promote the rainwater evenly into the role of the river More prominent, showing a strong water conservation and water management role.
