从石漠化的概念、成因、分级指标、防治对策等方面对我国石漠化问题的研究作了简要回顾。根据石漠化的形成机理及特点将石漠化的内涵作 了引申，分析了石漠化成因、石漠化分布及程度分级判别指标、石漠化防治理论等方面目前研究中存在的不足。指出我国石漠化问题应从以下几个方面加强：①对于石漠化问题的科学 概念和科学内涵应进一步深化；②在进行石漠化等级的划分和评价时，应根据导致石漠化发 生的因素，运用将现状和潜在危险性评价相结合的方法进行，且应注重加强定量评价方面的 研究；③急需在宏观尺度上对长江中上游地区土壤侵蚀机制、侵蚀过程、水土保持原理等方 面进行研究和探索，建立一套适合长江流域自身特点的理论体系，为石漠化地区的合理规划 和综合治理提供科学的理论依据。

The actual research state of rock desertification in China is reviewed in this paper from the conception, driving factors, classification index and prevention countermeasure and so on. On the basis of the mechanism and characteristic of rock desertification, the connotation of rock desertification is amplified, and the following insufficiency of the rock desertification research at present and the research emphases are put forward: ① The concept and connotation of rock desertification should be enlarged; ② The rock desertification classification and evaluation, should be combined with the actualities and potential risk of rock desertification from factors leading to generating desertification in the handling process, and the quantification evaluation strengthened; ③ The soil erosion mechanism, erosion process and principle? of soil and water conservation are urgently needed to be researched in large scale, and the theory system is also needed to established for providing the gist to the rational programming and synthetic treatment for rock desertification areas.
