在日本北部月降水量均匀分布的地区，研究了采伐后阔叶林转变为针叶林后产水量的变化。采伐后的年产水量大于阔叶林，然后随着针叶林的生长而降低。这种减少在种植针叶树苗30年后停止。这一阶段针叶林的产水量小于阔叶林的产水量。月产水量测定结果表明，年产水量的差异主要是由于常绿阔叶林和针叶林冬季截留损失量的差异造成的。上述结果表明，针叶林退耕还林可以用来提高这些地区的产水量。(C)2007 Elsevier B.V.保留所有权利。
This study examined the change of water yield when a broad-leaved forest is converted to a coniferous plantation forest after clear-cutting in northern Japan where monthly precipitation is evenly distributed. Annual water yield after clear-cut was greater than observed in a broad-leaved forest and then decreased with the growth of a coniferous plantation forest. This reduction ceased after 30 years from the planting of coniferous seedlings. Water yield of a coniferous forest at this stage was smaller than observed in a broad-leaved forest. Results from monthly water yield examinations suggested that the difference in annual water yield was primarily caused by the difference in winter interception loss between broad-leaved deciduous and coniferous evergreen forests. The above results suggest that converting coniferous forests into broad-leaved forests can be used to increase water yield in these regions. (C) 2007 Elsevier B.V. All rights reserved.
