分析了中国土地荒漠化对土壤碳影响的相关研究文献发现，由于历史和现实的原因，国内荒漠化区土壤碳研究存在理论和实证不足，没有适用的计算方法等问题；对维持我国可持续发展起关键作用的青藏高原及西南喀斯特石漠化区的土壤碳研究尤其欠缺。由此导致无法解释中国荒漠化生态系统碳源、碳汇的大小、分布及其变化这样一个重要的科学问题。急需开展以下方面的基础研究工作，加强荒漠生态系统土壤碳循环方面基础数据的收集整理工作；进一步加强荒漠生态系统碳库收支计算方法的研究；加强我国荒漠化地区土壤碳源、碳汇的实证研究；加强对青藏高原、南方喀斯特石漠化区等对维系我国可持续发展起关键作用的特定区域的土壤碳库收支的基础研究。以便全面、系统地估算和评估中国荒漠化地区碳源、碳汇的大小、分布及其变化，为更好的应对全球气候变化提供决策依据。

We've analyzed and summarized the literatures about soil carbon in desertification area of China and found that there were two major issues on soil carbon in desertification area in China for historical and practical rea-sons.First,lack of enough real evidence and no appropriate method to use.On the other hand,the study on soil carbon in Qinghai Tibet Plateau and the Karst rocky desertification area in Southwest of China,which plays an im-portant role in maintaining the sustainable development of China,were especially deficient.So,scholars could not answer the follow key scientific questions:in China,how was the size of the soil carbon sources and sinks in deser-tification area?How were they distribution and variation?Therefore,it was important for us to carry out basic re-search work in these fields.Firstly,it should strengthen collecting the basic data about soil carbon cycle of desert ecosystem.Second,pay more attention on the computational method of balance of payments about carbon stock of desert ecosystem.Thirdly,strengthen the empirical research on source and sink in desertification area of China.Fi-nally,strengthen the basic research on soil carbon balance for those areas such as Qinghai Tibet Plateau and the southern Karst rocky desertification area,which plays a key role in the sustainable development of China.In order to fully,systematically estimate and evaluate the regional carbon source and sink size,distribution and change.So we could finally offer the basis for how to deal with the global climate change.
