在2007年,本文采用环刀法和烘干恒重法对大青山不同植被类型土壤物理特性和旱、雨季土壤含水量进行了研究。结果表明:林地土壤物理特性明显好于荒草坡,白桦天然次生林要好于人工林;土壤旱雨季的含水量的变化与各时期内土壤有效水的排序有很大的不同,旱季土壤含水量大小排序为落叶松人工林、白桦天然次生林、灌木林、油松人工林、荒草坡,而土壤水分的有效性排序为落叶松人工林、荒草坡、白桦天然次生林、油松人工林、灌木林。在雨季的时候有林地的贮水能力要好于荒草坡和灌木林,雨季土壤含水量于其土壤理化性质排序一致,并且有显著的相关性,在土壤有效水和含水量方面降雨对油松和荒草坡的水分变化影响最大。
In 2007, the paper studied the soil physical characteristics and the soil moisture content in the rainy and dry season days in different vegetation types of Daqingshan by using the ring cutter method and the constant dry weight method. The results showed that the soil physical characteristics of woodland were significantly better than that of the grassland, the natural secondary forest of Betula platyphylla was better than that of plantation. The change of soil moisture during the dry season was very different from the order of available soil water. Larch plantation, Betula platyphylla secondary forest, shrub forest, Pinus tabulaeformis plantation and Scrubland slope. The order of soil water availability is Larch plantation, Scirrell slope, Betula platyphylla secondary forest, Pinus tabulaeformis plantation and shrub forest. During the rainy season, the water storage capacity of woodland was better than the grassland and shrubbery. The soil moisture content of rainy season was consistent with the order of physical and chemical properties of soil, and there was a significant correlation between the available water and water content. Grassland slope water changes have the greatest impact.
