摘要
在森林区域内,大气降水、穿透雨、树干径流、地表径流和集水区径流5种类型水样的表现性状可以大致模拟大气降水对森林垂直层面的作用与影响。本文通过对2020年3月-10月期间鸡公山森林区域内的上述5种类型水样的pH值等水质指标进行定位观测和对比,得到了该区域内穿透雨、树干径流和地表径流的大部分指标浓度值高于大气降水从而呈现正向效应,集水区径流的大部分指标浓度低于大气降水则呈反向效应的结论。并通过对实验结果的分析,阐释了大气降水透过森林林冠层、林下枯落物层的元素变化规律,为深入研究森林水文的内在运行机制提供依据。
In the forest area,the performance characteristics of five types of water samples,including atmospheric precipitation,throughfall,trunk runoff,surface runoff and catchment runoff,can roughly simulate the effect and influence of atmospheric precipitation on the vertical layer of forest.In this paper,through the positioning observation and comparison of the pH value and other water quality indicators of the above five types of water samples in the Jigongshan forest area from March to October 2020,and the results showed that the concentration values of most indicators of throughfall,trunk runoff and surface runoff in this area were higher than that of atmospheric precipitation,which showed a positive effect.Most of the index concentration of runoff in catchment area is lower than that of atmospheric precipitation,which shows reverse effect.Based on the analysis of the experimental results,the element change law of atmospheric precipitation through forest canopy and litter layer is explained,which provides a basis for further study of the internal operation mechanism of forest hydrology.
