我国西南部喀斯特地区石漠化研究进展

我国西南部喀斯特地区的石漠化是西部生态建设中面临的十分突出的地域环境问题，也是西南喀斯特地区实现可持续发展的主要障碍之一。参考国内研究的相关文献，运用比较分析法，从喀斯特石漠化的概念、分布、评价指标、生态效应、成因分析及综合治理等六方面回顾了近年来我国喀斯特地区石漠化研究的进展情况。研究结果认为，目前研究中还存在基础理论研究落后于实践活动、定量分析不足、基础数据采集工作欠缺和现有治理模式具有较大的局限性等不足，并建议从研究重点区域、探究喀斯特石漠化演变机理、在喀斯特石漠化地区开展生态综合整治工作及建设相关的信息系统等方面开展先行研究工作。

Progress of research on rocky desertification in karst areas of southwestern China

Rocky desertification in karst areas of southwestern China is an outstanding regional environmental issue, and is also one of the main obstacles to regional sustainable development. This paper reviews the progress in research on karst rocky desertification, including the concept, distribution, evaluation index, ecological effects, cause analysis and integrated control. It is pointed out that four deficiencies exist in the current research, i.e. the lag of the basic theory behind the practice, insufficient quantitative analysis, lack of basic data and the limits of existing control Finally this paper proposes several aspects for future research.
