摘要
围绕樟子松等人工针叶林,研究了林地水分收支途径及其比例关系和土壤水分的变化,阐明了水分平衡状况,以及在保证水分平衡的条件下,估算了25—30龄林的合理水分密度,为确保林木正常生长所必需的土壤水分供应,提供了科学依据。
With the object of artificial forest, the paper studies the ways for
soil water to supply and consume, the proportion between each way. as well
as the change in water content. So water balance of studied soil is expou-
nded. Furthermore, the authors estimate the reasonable density of conifers
when soil water is balanced, this guarantees enough water for tree's grow-
