自然土壤的形成过程是在自然力的支配下进行的,而在耕种土壤中所发生的所有的过程在很大的程度上,都是取决于人类经济活动的影响,因此,这二个过程不但只是在内容上有着显著的不同,而且就它们作用力的本质来说,也是截然不同的。从这样的观点出发,我们可以认为自然土壤和耕种土壤的形成过程彼此是有着独立的意义的。很多资料都证明,耕种土壤的形成不能认为和自然的土壤在演化上有着直接的相继性,它决不是“土壤形成过程的现代的更高的阶段”(威林斯基土壤学第89页)。
The process of natural soil formation takes place under the control of natural forces, and all the processes that occur in the cultivation of soils depend to a large extent on the economic activities of human beings. Therefore, these two processes are not only There are significant differences in content and, in terms of the nature of their forces, are quite different. From this point of view, we can assume that the formation of natural and cultivated soils is independent of each other. Numerous sources have proved that the formation of cultivated soils can not be considered as direct succession to natural soils and is by no means “a modern, higher stage of the soil formation process” (Willingsky Soil Science, p. 89) .
