据估计，每年从陆地河岸森林进入河流生态系统的外来物质的数量是相当可观的，来自落叶分解的物质被认为对河流水质有重要影响。本研究的目的是澄清万年青树种，主要是在河岸带的调查流的叶凋落物的淋溶特性，并检查淋溶液对山溪水离子组成的影响，通过实验室淋溶实验和现场测量。将5片新鲜落叶和10种主要万年青树种的落叶置于装有500 cc蒸馏水的烧杯中，在25~30 ℃的环境温度下放置30 d。。
The amount of allochthonous material that enters lotic ecosystems annually from terrestrial riparian forests is estimated to be considerable, and substances derived from the decomposition of leaf litter are thought to have an important impact on stream water quality. The purpose of the present study is to clarify the leaching characteristics of leaf litter of the evergreen species that are dominant in the riparian zone of the investigated stream and to examine the influence of leachates on mountain stream water ionic composition by laboratory leaching experiments and field measurements. Five fresh fallen leaves and fallen leaves of ten species of evergreen trees dominant in the riparian zone of the investigated reach were placed into a beaker filled with 500cc of distilled water and allowed to stand for 30 days at ambient temperature between 25~30 。 。
