关于喀斯特石漠化类型划分问题的探讨

喀斯特石漠化是一种比较特殊的荒漠化类型,我国石漠化研究时间短、涉及学科多、跨部门、跨行业,目前还存在诸多的问题和难点有待进一步深入研究。文章简述了石漠化的发展与研究历程,列举了对喀斯特石漠化科学内涵的代表性观点。针对喀斯特石漠化类型划分问题,综述了目前的分类评价研究现状与进展,指出了其中存在的问题与不足,认为这从一定程度上制约了理论研究以及实践应用的发展。喀斯特石漠化类型的划分应以其成因为基础,体现导致石漠化的根本及内在因素,区别出自然石漠化以及人为石漠化,并能够为石漠化地区生态系统的恢复与重建提供科学依据。

Discussion on the Classification of Karst Rocky Desertification

Karst desertification is a special type of desertification, however in China it is a new research field and involves many disciplines, departments, and industries. There remain many problems and difficulties to be explored. The author discussed research history, and enumerated the representative points about the scientific connotation of karst rocky desertification. Aiming at the classification of karst rocky desertification, this paper summarized the current classification evaluation and its latest development, and pointed out some problems and insufficiency, which restricts the development of the theoretical research and practical application to some extent. The classification of karst rocky desertification should be based on its genesis, and could embody the fundamental and internal factors, and distinct between natural desertification and human desertification. And it should provide scientific basis for restoration and reconstruction of ecosystem in karst rocky desertification regions.
