9. 研究结果摘要本研究受到关注；三个主题如下： 1．通过对日本杉树和落叶树的调查，随着雨水运动的溶解元素垂直变化，到达森林地面的水量减少了80%左右，水质发生了很大的变化。阔叶林占主导地位的橡树。因为提供给森林生态系统的降水被森林树冠拦截了。也指出了灌木丛的重要性。通过吞吐量增加的离子量被分离 通过对树木冲刷和淋洗的两个主要原因进行分析，得出湿沉积、干沉积和树冠2。土壤水质量的形成采用IER方法研究了森林土壤中水溶性碱阳离子的动态变化，以明确土壤系统土壤水质量的变化。氮矿化对土壤水质量的影响TOO.3 河流水质形成。研究了修剪和疏伐对河流水质形成的影响，明确了河流水质形成的机理。各量之间的关系 森林生态系统中主要水路的水流质量是通过土壤层和梨状物质对水溶性碱阳离子的吸附和淋滤来保持物理化学平衡的。
