The purpose of this research was to make clear transport phenomena of materials through vadose zones, which are still vague mainly because of the lack of knowledge in missing sinks and missing sources of them. We succeeded in obtaining new findings :(1) salt accumulations due to fluctuations of relatively shallow groundwater levels,(2) excess CO_2 emission from soils to the atmosphere due to infiltration of rain water,(3) irregular CO_2 emission from soils to the atmosphere due to the priming effects after application of organic matters,(4) unique accumulation of carbon inside the soils under forest fire events, and(5) missing sources and missing sinks in vadose zones under possible climate changes.

本研究的目的是明确物质通过包气带的输运现象，这仍然是模糊的，主要是因为缺乏知识的失踪汇和失踪的来源。结果表明：（1）相对浅的地下水位波动引起的盐分积累;（2）雨水入渗引起的土壤CO_2过量排放;（3）施用有机质后的启动效应引起的土壤CO_2不规则排放;（4）森林火灾时土壤中碳的独特积累;（5）可能的气候变化引起的包气带碳源和汇的缺失。
