摘要
分析了南方红壤丘陵区农业景观特征,提出该区重点治理的生态脆弱带为低丘岗地,认为该地带的人为干扰和自然作用不相协调是本区农业景观的不良演替的原因。初步探讨了通过农业合理布局,促进该区景观恢复的途径。指出作物布局和土壤耕作对低丘岗地保护、开发及景观恢复等方面的意义。
Characteristics of the agro-landscape in the red soil hilly region of South China areanalysed.The low hilly section was referred to the ecotone with mal-succession,whichwas resulted from the disharmonization between human distruhances and nature,and sho-uld be the focus of improvement.Futhermore.agro-landscape construction is promoted byadjusting the agro-layout through establishing the apropriate farming systems and deve-loping optimal utilization model.Techniques of agroforestry and conservative soil tillageand management are considered as very important techniques in the conservation,rehabi-litation and reclaiming of the natural resouces of low hills in red soil hilly region ofSouth China.
