摘要
对桥山林区油松林水量平衡的各分量进行了研究,以评价其水源涵养功能。结果表明,生长季节油松林的蒸腾耗水量为178.5—360.1毫米,占同期降雨量的54.9%—110.7%,是林分水分消耗的主要部分。一次性降水过程中油松林的总拦蓄能力为82.1—124.4毫米,林地的稳渗系数为12.6—38.4毫米/小时。一般不会因地表径流而产生水土流失。根据上述结果,对该区油松林的经营提出了相应建议。
The factors of water balance in Chinese pine forest of Qiaoshan mountain is studied to evaluate its function in water conserving.The results show that the water consumption of the Chinese pine forest through transpiration is 178.5—360.1mm during growing season, being amounted to 54.9% —110.7% of the precipitation in the same period and regarded as the major part of water consumption of the forest.The total reserving capacity of the forest in a single rainfall is 82.1—124.4mm, the coefficient of stable infiltration is 12.6—38.4mm/h..So soil loss could not occur from overland flow.Based on the results some suggestions on management of the foerst are raised.
