THE FUNDAMENTAL CHARACTERISTICS OF MOUNTAINOUS AND HILLY SOILS IN SOUTHEAST FUJIAN PROVINCE

Fujian is one of the mountainous provinces in China.The plains are formed as narrow strips along the southeastern coast with mountains behind facing the sea.The high mounrains of central Fujian predominated by the Daiyunshan mountains are stretched and distributed in the northwest part of the province which is under middle subtropical climate;while in the south-east part,it belongs to south subtropical climate.In this region,from hilly land in Quanzhou plain up to the summit of Mt.Daiyunspan,the vegetations change from the subtropical rain forest,the evergreen broad-leaved forest,the mixed deciduous and evergreen broad-leaved forests,the coniferous forests dourinated by Pirtus taiwanensis to mountain shurbs,and finally to meadow grasses with sealtered dwarf Pinus taiwanensis.Correspondingly,the soils change from lateritic red earth,red earth,mountain red earth,mountain yellow-red earth to mountain yellow earth,and finally to the mountain meadow soil.
