| 摘 要： | 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。

| Abstract: | The soil moisture characteristics of 30a Pinus tabulaeformis plantation in south slope of Daqing-Mountains were studied.The results showed that(1) In 0~20cm layer,the soil moisture seasonal dynamics were similar to the change of rainfall amount,the peaks appeared in July.In 20~60cm layers,the soil moisture changed slightly and stayed on one level.(2)The vertical distribution of soil water could be divided into three layers,variable speed-layer,active-layer and relatively stable-layer.(3) The soil moisture d... |
