摘　　要：南方红土区是我国农业生产的重要地区之一,也是我国南方的重要生态安全屏障。本文在总结该区的地质地貌背景及存在的主要资源和生态环境问题的基础上,以武夷山市为例阐述了在南方红土区开展地表基质调查的思路与方法,总结了调查区红土型基质的类型、分布、结构及理化性质特征,研究了不同基质类型在林改园过程中的元素迁移规律及其生态效应。研究表明,南方红土区地表基质调查应当以地质背景和基质成因为主控因素划分填图单元,再结合填图单元内的地貌特征和生态格局部署实物工作;红土区地表基质调查应当分层次进行,且不同层位调查内容应当有所侧重;红土型基质以物理风化为主,基质的不同利用方法对其理化性质起着影响作用。The red soil region in South China is one of the important areas for agricultural production in China,and it is also an important ecological security barrier in the south of China.This paper,taking Wuyishan City as an example,expounds the ideas and methods of conducting ground substrate survey in the southern laterite region,and summarizes the types,distribution,structure and physical and chemical characteristics of laterite substrate in the investigation area.The law of element migration and its ecological effects of different substrate types in the process of transforming forest into garden are studied.The results show that the mapping units should be divided according to the geological background and substrate genesis,and the physical work should be deployed according to the geomorphological characteristics and ecological patterns in the mapping units.The survey of ground substrate in laterite area should be carried out in different layers,and the survey contents of different layers should have different emphasis.The laterite substrate is mainly weathered by physical weathering,and different utilization methods of the substrate affect its physical and chemical properties.
