—、土壤剖面之生成土壤剖面之发育,主为气候、地形、母岩、生物、排水等地理因素所支配,故在不同之地理区域,生放之土壤剖面各异。概言之:新蒙等地之乾旱区,常为漠钙土,且因雨水稀少,不足将土中之可溶性盐类及石膏等淋失,更因毛细管作用而上升,故盐类及石膏之淀渍常 -, the profile of the soil profile generated by the development of the soil profile, the main climate, topography, rock, biological, drainage and other geographical factors dominated, so in different geographical areas, the release of soil profiles vary. In summary: the new Mongolia and other places of arid areas, often as desert soil, and due to scarce rain, the soil will be soluble salts and gypsum leaching, but also due to the role of capillary rise, so the salt and gypsum Drain often
