摘要:
本文作者研究了25～28年生人工油松（Pinus tabulaeformis）林地土壤水分在6m剖面上的分布状况、补偿能力、季节动态以及坡向、部位对土壤水分的影响和采伐迹地土壤水分的恢复能力。研究结果表明，人工油松林土壤水分含量很低，在整个剖面上通常变化在9%～11%之间，低于稳定湿度；在雨季末，林地土壤水分补偿深度为100～200cm；土壤水分季节动态，在强烈利用层十分活跃，变幅为13.5%～26.5%，在利用层变化较小，平均为10.0%～15.0%。油松人工林采伐迹地土壤水分恢复能力强，当年可恢复到2.8m，达稳定湿度以上，3年可恢复到4.0m，含水量达13.0%～18.0%。
Abstract:
The distribution of soil moisture,its compensation ability and dynamics in season in soil profile of �m., as well as, the influence of the exposure and position of slope on soil moisture and its restoring ability in cut-over land were studied in plantation of P. tabulaeformis at the age of 25～28. The results of the studies indicated that the soil moisture content in the plantation varied usually from 9% to 11% in all profiles,that is lower than stable humidity. The compensation depth of soil moisture in the end of raining sea-son reached 1～2m.The soil moisture content in the layer of intensive utilization fluctuated from 13.5% to 26.5%, in utilization layer, on an average, 10.0%～15.0%,and in the layer of adjustment for supplement it was mainly stable, the annual amplitude was only 9%～10%. The restoring ability of soil moisture in the cutover land of P.tabulaeformis plantation was great,the soil moisture might be restored to the depth of 2.8m the same year and of 4.0m in 3 years, where the soil moisture content reached 13.0%～18.0%.
