基于社会-生态系统理论的土地健康诊治框架

A diagnostic framework for land health based on social-ecological systems

为实现土地资源可持续利用,构建人地关系视角下的土地健康诊治框架。运用CiteSpace文献计量方法,对土地健康研究进行知识图谱分析,同时基于社会-生态系统(Social-ecological systems,SESs)理论,构建土地健康诊治框架。结果表明:1)土地健康科学内涵的发展过程可作为土地生态系统与社会经济知识健康运行的诊治依据;2)土地健康研究呈现多元分散特征,健康机理、评估方法与实践层面适应性管理是研究热点;3)土地健康诊治框架将社会经济系统和土地生态系统有机整合,由外部驱动子系统、内生驱动子系统和土地利用系统表征3部分组成;4)该诊治框架可以根据特定土地问题进行相应调整,适用性强。因此,基于SESs理论构建土地健康诊治框架有助于理解人地系统的作用过程和互馈机制。

The purpose of the study was to construct a diagnostic concept framework for land health based on socialecological systems(SESs),and achieve sustainable land management.Knowledge domain mapping analysis was conducted on land health based on CiteSpace literature review method.The results show that:1)The concept evolution of land health can be used as diagnostic criteria for determining land ecosystem and social-economic functioning healthily;2)Researches on land health are focused on the mechanism,methodology,and practical management,indicating a diverse and distinct characteristic;3)The diagnostic framework mainly consists external drive subsystem,internal drive subsystem and land use system,and successfully integrates socio-economic system and land ecosystem;4)The structure of diagnostic framework is problem oriented,which is strongly adaptive and can constantly be revised according to the evaluation results.In conclusion,the diagnostic framework bridges the gap regarding the cognition of processes and cross-feedback mechanism of human-land relationship.This study provides a novel insight to improve the harmony between humankind and nature.
