摘要: <正>对黄前库区森林主要类型刺槐林和油松林土壤涵蓄降水作用的研究结果表明:森林土壤的渗透性能以刺槐林地最好,阳坡油松林次之,阴坡油松林最差;森林土壤恢复持水,即连续涵蓄降水的能力较强,2h恢复的持水量可相当于20.5~33.2mm的降水;3种森林类型的地表径流量和土壤侵蚀量均表现为阳坡油松林最大,阴坡油松林次之,阳坡刺槐林最小;降雨量越大,地下径流出现的时间越早,高峰期出现的时间越晚;同样降雨量情况下,3种森林类型地下径流和高峰期出现时间均表现为阴坡油松林最晚,阳坡刺槐林次之,阳坡油松林最早。

Abstract: The paper deals with the role of the main forest soil types of locust plantation and Chinese pine plantation on interception of precipitation in Huangqian reservoir area.The results show that (1) for the soil permeability performance,the order of locust is:woodland,sunny slope Chinese pine woodland,shady slope Chinese pine woodland;(2)the ability of forest soil on recovering water conservation is strong,in 2 hours the recovering percentage can be from 17.1% to 22.1% of maximum retention amount,and this is equal to 20.5~33.2 mm of precipitation,in 4 hours the recovering percentage can be from 28.0% to 30.9% of maximum retention amount,and equal to 33.6~46.5 mm of precipitation,in 48 hours the recovering percentage can be from 42.6% to 57.8% of maximum retention amount,and equal to 60.5~87 mm of precipitation;(3)both for the surface runoff amount and soil erosion amount,the order is of sunny slope Chinese pine woodland,shady slope Chinese pine woodland,sunny slope locust woodland;(4)the bigger the precipitation amount is,the earlier the arriving time of ground runoff is,and the later the peak time is,under the same precipitation amount condition,the arriving time of ground runoff and peak time for different forestry type is different,shady slope Chinese pine woodland is latest,sunny slope locust woodland is later,sunny slope (Chinese) pine woodland is earliest.
