对大青山区阳坡30a油松人工林生长季土壤水分特征进行研究,根据2006年的观测数据分析,得出以下结果:1)油松人工林0~20cm层土壤水分季节动态与降雨量变化相似,7月份土壤含水量最高,后逐渐减小趋于平缓,20~60cm层随季节变化波动很小,基本呈现水平趋势;2)土壤水分在垂直分布上可分为土壤水分速变层、活跃层、相对稳定层;3)0~60cm土层范围内,土壤含水量随密度增加,呈下降趋势,但表层变化规律不显著。 According to the analysis of observation data in 2006, the following results were obtained: 1) Seasonal dynamics of soil moisture and rainfall in 0-20 cm layer of Pinus tabulaeformis plantation Similarly, the soil water content in July was the highest, and then gradually decreased to be gentle. The 20-60 cm layer fluctuated little with the seasons, showing a horizontal trend. 2) The vertical distribution of soil moisture could be divided into three types: Active layer and relatively stable layer. 3) Within 0 ~ 60cm soil layer, the soil water content decreased with the increase of density, but the variation of surface layer was not significant.
