摘　　要：小良地区过去是一个典型的水土流失区,现在已基本上得到了有效的治理,为了使小良能保持可持续发展,我们必须要认真研究导致水土流失的主要因素———气候水文因素,避免历史的悲剧重演。在简要分析水土流失的成因及地形地势、岩土性质、森林植被等因素对水土流失的影响的基础上,进一步运用灰色理论对气候水文这个主要因素对水土流失的影响进行了相关度的分析,突出气候水文因素对水土流失影响的重要地位。Xiaoliang area used to be a typical area with soil and water loss, while so far, which has been carried out some basic effective control. In order to maintain the sustainable development of Xiaoliang area and to avoid the repeat of the historic tragedy, we must do more research on the main factor which leads to soil and water loss - the climatic hydrographic factor. This paper starts with a brief analysis of the causes of soil and water loss, and the effects on it from terrain and relief condition, geotechnical property, forest cover, and so on. Further study is implemented the correlation degree analysis using grey theory on the main factors of soil and water loss, and climatic hydrographic factor. The significant effect of climatic hydrographic factor on the soil and water loss is emphasized.
