关于岩石性质与水土流失的关系,过去曾有不少文章进行论述。但是,从岩石的结构构造、岩石(或岩体)组合结构特征、岩层产状陡缓、岩石风化物的抗蚀能力及侵蚀形式等方面论述岩石性质与水土流失关系的研究还较少。为了提高人们从本质上认识水 土流失这一自然现象,本文以江西省为例,从上述这些方面谈谈岩石性质与水土流失的关系.一、概述江西省岩石类型齐全,沉积岩、变质岩、岩浆岩三大岩类分布广泛(表1).岩
There have been many articles on the relationship between the nature of rocks and soil erosion. However, there are few researches on the relationship between rock properties and water and soil loss in terms of the structural structure of rock, the features of rock (or rock mass) assemblage, steep rock formation, the corrosion resistance of rock weathering materials and the erosion patterns. In order to raise people’s awareness of the natural phenomenon of soil and water loss in essence, this paper takes Jiangxi Province as an example to discuss the relationship between the nature of rock and water and soil loss from the above aspects.One, it is summarized that the rock types in Jiangxi Province are complete, sedimentary rock, metamorphic rock, magma Rocks are widely distributed among three major rock masses (Table 1)
