摘要：

2011-2012连续2a在玛曲县欧拉乡牧户的夏季草场研究短期休牧对不同月份、不同土层土壤含水量的影响。结果表明,短期休牧能显著提高青藏高原东缘高寒草甸区夏季草场0~30cm土层的土壤含水量,但对30cm以下土层的土壤含水量无显著影响;随着月份推移,休牧和放牧草地0~20cm土层的土壤含水量逐渐降低;短期休牧草地的土壤含水量整体高于放牧草地,且随月份的推移,二者的差距逐渐减小,7月份0~10cm土层的差距最大,10月份20~30cm土层的差距最小。

摘要：

The effects of the short-term rest grazing on soil moisture content in different months of summer pasture of the typical farmer in Maqu county from 2011 to 2012and soil layers was studied in eastern alpine meadow of Qinghai-Tibet plateau.The results showed that the short-term rest grazing could increase soil moisture content in layer 0-30 cm significantly,but it had no significant effect on soil moisture below 30cm;from July to October,the soil moisture content for the grazing and rest pasture decreased gradually;the overall soil moisture content for the short-term rest grazing was higher than that of the grazing pasture,but the gaps were shorten gradually from July to October.The biggest gap was found in July at the depth of 0-10 cm and the smallest gap was in October at the depth of 20-30 cm.
