樟子松等人工林土壤水分收支状况及其合理密度的初步研究

A Preliminary Study on Water Balance of Soil under Artificial Forest and Reasonable Density of Coniferous Wood

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龄林的合理林分密度，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。

ith the object of artificial forest, the paper studies the ways for soil water to supply and consume,the proportion between each way.as wellas the change in water content.So water balance of studied soil ls expounded.Furthermore, the authors estimate the reasonable density of conifers when soilwater is balanced, this guarantees enough water for the tree's growth.
