广东省花岗岩区侵蚀土壤类型及其防治对策

广东省花岗岩出露区面积大,不同侵蚀风化壳岩层为母质的土壤侵蚀过程和侵蚀类型区域差异明显,因此依据不同侵蚀土壤类型的特点进行治理显得十分必要.该省德庆县花岗岩风化壳土壤侵蚀非常严重.在对该地区花岗岩风化壳特性与侵蚀过程关系调查基础上,对花岗岩风化壳剖面分带特征及其物理化学垂直分异特点进行了分析,探讨了花岗岩区侵蚀土壤的发生机理,对花岗岩区主要侵蚀土壤类型、特点及其治理对策进行了讨论.

Eroding Soil Types and Their Management Countermeasures of Granite Regions in Guangdong Province,China

A area of granite region in Guangdong province is big,and regional differences of erosion processes and eroding types in different eroding weathering crust are very obvious. It is necessary that eroding soil is controlled according with their features.Soil erosion of granite weathering crust in Deqing county of Guangdong Province is very serious. Based on investigation to characteristics of weathering crust and erosion processes of this region,profile features of weathering crust and physical and chemical c...
