| 摘 要： | 在1990～1992年和2003年对长白山阔叶红松林土壤水分动态进行定位观测研究.结果表明，土壤水分年内变化可划分为5个时期：春季聚水阶段、旱季耗水阶段、雨季蓄墒阶段、秋季失墒阶段和冬春土壤水分相对稳定阶段.利用标准差和变异系数对土壤水分垂直变化进行分层，得出土壤水分剖面分布分为速变层、活跃层和次活跃层，并用相关分析方法分析了各层次间土壤水分及其与其间降水量的关系.

| Abstract: | The located observation on the soil moisture dynamics under broad-leaved Korean pine forest in Changbai Mountains in 1990 - 1992 and 2003 showed that the seasonal variation of soil moisture content could be divided into five periods, i. e., gathering water stage in spring, consuming water stage in arid season, holding water stage in rainy season, losing water stage in autumn, and relatively stable stage of soil moisture in winter-spring. By using standard deviation and variation coefficient, the vertical layers of soil moisture were divided into rapid change layer, active layer, and sub active layer. Correlation analysis was applied to analyze the relationships of moisture content among different soil layers and the correlation between soil moisture and precipitation in the same period. |
