成土母质之性质对於成土作用之影响,虽不若气候因子之大,但其对於风化作用之进行与夫土壤演变之过程实有不容忽视之力量,而尤以在岩石风化之初为甚,赣省侵蚀剧烈,沉积频繁,各类土壤或系岩石之新风化物,或与各期之沉积有关,故地质情形对於土壤之生成性态以及分布等关系异常密切,今请述之。 Although the nature of soil-forming parent material does not have a large climatic factor for its effect on soil formation, its force of weathering can not be neglected in the process of weathering and soil evolvement, especially in the early stages of rock weathering In particular, the severe erosion and frequent deposition in Jiangxi Province have resulted in the frequent occurrence of various types of soils or lines of newly-weathered rocks, or related to the sedimentation of various stages. Therefore, the geological conditions have an extremely close relationship with the formation and distribution of soil. .
