摘要:
在2005年5月19日至2005年9月13日研究了呼伦贝尔典型草原区自由放牧和围栏禁牧对0~110 cm土壤水分的影响情况，结果表明围栏禁牧对草原土壤水分的影响表现为提高20~70 cm土层的水分含量，而放牧提高了0~10 cm表土水分含量。呼伦贝尔典型草原自然降雨和冰雪的融化对土壤水分的影响深度为0~90 cm，在该范围内的土壤水分明显受降雨的影响。90 cm以下土壤在年内变化幅度较小，含水量在3%~5%之间。
Abstract:
The soil water of grassland in Hulunbeir during May 19th 2005 and September 13th 2005 was researched.The results as follows:firstly, fencing enhances the soil water that from 20 cm soil layer to 70 cm soil layer, and grazing enhances the soil water that from 0 cm soil layer to 10 cm soil layer;secondly, the precipitation and the thaw of ice and snow affect the soil water that from 0 cm soil layer to 90 cm soil layer, and under 90 cm soil layer, the soil water change range smaller during a year.
