苏浙皖边界低山丘陵区属天目山系余支,总面积约2000平方公里。本文研究了该区主要三种地带性土壤。山地自然土壤主要分布于海拔80—180米以上的山坡地,其形成以棕壤化为主,附加有弱富铝化过程,故拟称之谓黄棕壤。该土最适宜于生长松、杉、栎、檫木等优质树种和经济林毛竹。山麓自然土壤分布于山麓部位,脱硅及富铝化过程已很明显,但比较微弱,故拟定为黄壤。该土最适宜发展板栗、枣树和青梅等干果。丘岗耕作土壤广泛分布于丘岗部位,其形成是在富铝化过程的基础上,附加了耕作熟化过程,故拟定为耕型黄壤。该土最适宜发展诸如茶,油茶等经济植物。
Jiangsu, Zhejiang and Anhui border hilly area belongs to the branch of the Tianmu Mountains, with a total area of about 2000 square kilometers. This paper studied the three main types of soils in the area. The mountainous natural soils are mainly distributed in hillsides above 80-180 meters above sea level. The formation of brown earth is dominated by brown soil, with the addition of a weakly aluminometallurgical process, hence the so-called yellow-brown soil. The soil is most suitable for the growth of pine, fir, oak, alder and other high quality tree species and economic forest bamboo. Piedmont natural soil distribution in the foothills, desilication and Al-rich process has been very obvious, but relatively weak, it is proposed as yellow soil. The soil is most suitable for the development of chestnut, jujube and plum and other dried fruit. Hilly farming soil widely distributed in the hillock site, the formation of the aluminum-rich process, based on the additional farming and curing process, it is proposed for the farming yellow soil. The soil is most suitable for the development of economic plants such as tea, tea and so on.
