新泰土门林场4种林地土壤蓄水性能及渗透速率的研究

Study on Soil Water-holding Capability and Permeation Speed under Four Kinds of Forestland in Xintai Tumen Tree Farm

研究了新泰市土门林场内麻栎、刺槐、侧柏和油松四种林地土壤的蓄水性能和渗透速率。结果表明：四种林地土壤的蓄水能力和渗透速率均明显高于荒坡地。四种林地0～20 cm土壤层的土壤含水量均高于20～40 cm层;四种林地0～20 cm和20～40 cm土壤层的蓄水能力从大到小的顺序均为刺槐林〉麻栎林〉侧柏林〉油松林。四种林地土壤的渗透系数从大到小依次为刺槐林〉麻栎林〉侧柏林〉油松林。

This article studied the soil water-holding capability and permeation speed under the four kinds of forests of Quercus acutlsslma Cart, Robinia pseudoacacia Linn, Platycladus oriental and Pinus tabulaeforrnls Cart in Xintai tureen tree farm. The resuhs showed that the water-holding capacity and permeation speed of the forestlands were both obviously higher than that of barren slope. The soil water-holding contents of the four kinds of forestlands in 0～20cm soil layer were higher than in 20～40cm soil layer. The sequences of water-holding capacity of the four kinds of forestlands were： Robinla pseudoacacia Linn forestland〉 Quercus acutissima Carr forestland〉 Platycladus oriental forestland〉 Pinus tabulaeformis Carr forestland. The sequences of infiltration coefficient of the four kinds offorestlands were： Robinia pseudoacacia Linn forestland〉 Quercus acutissima Carr forestland〉 Platycladus oriental forestland〉 Pinus tabulaeforrnis Carr forestland.
