通过对原有刺槐林地、实行更新改造后形成的萌生幼林地和各种形式的刺槐、油松混交林地土壤水分的测定，结果表明：对刺槐林实施改造后，林地水分状况明显改善，土壤湿度平均提高１７．４２％；林地土壤干层未因改造措施而消失，但其出现的位置会发生一定的变化；土壤水分的季节动态分析表明，各林地在４０ｃｍ以下直到２００ｃｍ土层均属于次强度变化或弱度变化土层，从而说明２ｍ深层土壤水分仍然受林木根系吸水的影响；对刺槐实施改造后，林地在生长季节的蒸散耗水量有增大的趋势。
Through the original Robinia pseudoacacia forest land, the implementation of the regeneration of the formation of young seedlings and various forms of Robinia pseudoacacia, Pinus tabulaeformis forest soil moisture determination results show that: after the implementation of the Robinia pseudoacacia forest transformation, the forest water conditions significantly improved soil moisture The average dry weight of forest soil did not disappear due to the transformation measures, but some changes occurred in its position. The seasonal dynamic analysis of soil moisture indicated that the soil strength below 40cm and 200cm in each forest belonged to the secondary strength Change or weakness of the soil layer, indicating that 2m deep soil moisture is still affected by water absorption of forest roots; after the transformation of Robinia pseudoacacia, woodland in the growing season of evapotranspiration water consumption increases.
