摘　　要：水土流失与社会经济系统的相互作用关系复杂且具有明显的时空变异性。以南方红壤区为核心,从区域尺度阐述了经济发展、人口规模、农业投入及农业产出等社会经济因素与水土流失及其治理的相互作用。在此基础上,从微观尺度剖析了水土流失治理工程驱动下农户生计方式的改变,以及农户社会网络对水土流失治理工程实施的影响。最后提出今后研究的重点:明确宏观发展规划及区域产业结构调整等对水土流失的影响机制,优化资源配置以提高水土流失治理成效;解析城镇化、农业集约化等新发展模式下农户生产方式、社会网络与水土流失治理工程的相互影响,推动水土流失治理工程的可持续运维。The relationships between soil erosion and socioeconomic systems are complicated,and have spatial and temporal heterogeneity.Focusing on the red soil region of Southern China,we analyzed the interaction of economic,demographic,agricultural input and output factors with soil erosion and its control in a regional scale.Then,we explored the changes of farmer′s livelihood pattern driven by erosion control project,and the influence of farmer′s social networks on the implementation of the erosion control project.Finally,we proposed several potential hot spots for future research,including the impact of macro development planning and regional industrial restructuring on soil erosion,optimizing resource allocation to improve the effectiveness of soil erosion control,response of soil erosion to new development patterns such as urbanization and agricultural intensification,interaction between farmers production and social network and soil erosion control projects,sustainable operation and maintenance of soil erosion control projects.
