以低于林地最大土壤含水量平均值为标准界定了低功能水源涵养林地标准。在此基础上，以河北北部地区华北落叶松人工林为例，研究了不同立地条件下，林分等树高曲线、等直径曲线、等密度曲线、自然稀疏曲线、蓄积量与土壤最大含水量之间的关系，编制华北落叶松人工林土壤水源涵养功能关系图，并阐述土壤水源功能关系图的在实际生产中的应用。

According to the standard below the woodland maximum average soil water con-tent ,the function of water conservation forest was first defined as low standard ,on the basis of which the relationship between the maximum soil moisture content and its stands ,tree height curves ,equal diameter curves ,density curves ,self-thinning curves ,and volume of Larix principis-rupprechtii forests under different site conditions in the northern Hebei areas was studied .Simultaneously ,a soil water conservation function diagram of Larix principis-rupprechtii plantation was established ,and the soil water function diagram application in practical production was elaborated .
