| 摘 要： | 土壤呼吸是土壤碳库输出的主要途径,凋落物是影响土壤呼吸的重要因素。明确凋落物对土壤呼吸的贡献,有助于准确评估植物-土壤-大气三个碳库之间的碳收支过程。本文综述了近年来国内外有关凋落物对土壤呼吸贡献的研究成果,阐明了凋落物对土壤呼吸的贡献机理,讨论了凋落物对土壤呼吸贡献率及其存在的时空分异特征,在此基础上,对该领域研究前景进行了展望。

| Abstract: | Soil respiration is the main approach for the output of soil carbon pool and litter is an important factor to affect soil respiration. It is vital to understand the effect of litter decomposition process on soil respiration, because carbon budget among plant-soil-atmosphere carbon pool plays a key role in terrestrial carbon circle. This paper illuminates the contribution mechanism of litter to soil respiration, reviewed the contribution rates of aboveground litters and belowground litters of different plants to soil respiration. In addition, it also pointed out that the future study fields for understanding further the responses of terrestrial ecosystem to global climate change. |
