| 摘 要： | 介绍土壤呼吸对于林地树木生长的重要性。分析人工干扰等外力作用导致土壤压实,使土壤容重增加,改变土壤孔隙度和二氧化碳浓度等。通过对影响因素和机理的分析,从微观角度利用微分原理,推导出土壤压实对土壤呼吸影响的数学模型,并就各主要影响因素对土壤呼吸的影响进行简要分析。

| Abstract: | The significance of the soil respiration for tree growth in forest land was introduced.The soil compaction caused by the human activities such as forest operations resulted in the soil bulk density increasing,soil porosity decreasing and the con- centration of carbon dioxide changed.Through the study of the influencing factors and mechanism from microscopic point of view, the mathematics model that describos the effects of soil compaction on soil respiration was established by using differential theory. |
