摘要：采用定位观测方法与小集水区试验技术方法 ,利用 1　 6月份观测数据 ,从土壤水分、坡面径流、集水区径流量等方面对大岗山地区人工针阔混交林、天然常绿阔叶林典型森林集水区的森林水文月动态变化规律进行了研究。结果表明 :(1)人工针阔混交林森林土壤水分最大值 (5 1 8mm)出现在 5月份 ,最小值 (33 2mm)出现在 3月份 ,且垂直变化幅度不大。 (2 )坡面径流量月变化较大 ,与一次性降水有密切关系 ,可用指数式y =0 .12 6 6e0 .0 50 2x表示。 (3)与人工针阔混交林相比 。
This paper, based on methods of experiment technique and the data of collected from observation, the forest hydrology monthly dynamics of artificial mixed stands of coniferous and broad leaved trees and nature stands of evergreen broad leaved trees in Dagangshan district were studied, including soil moisture, surface runoff and total runoff. Some analysis results are as follows: (1)The maximum of soil moisture(5.18 mm) of artificial mixed stands of coniferous and broad leaved trees occurred in May, the minimum occurred in March; the distribute change of moisture in the depth is not obviously. (2)The surface runoff monthly change is greatly, and one off rainfall obviously affects soil moisture ( R 2 =0.939 5). (3)Compared with artificial mixed stands of coniferous and broad leaved trees, nature stands of evergreen broad leved trees had good effect of prevention of water and soil erosion and function of water conservation.
