空间恢复力理论支持下的人地系统动态研究进展

Research progress of human-earth system dynamics based on spatial resilience theory

人地系统的概念表现了人与地在特定的地域中相互联系、相互作用而形成的一种动态结构,面向人地系统动态运行过程的复杂性,亟待构建更有力的指标体系表征地球系统和人类系统相互影响与反馈的过程。空间恢复力可以被理解为以保障人地系统结构稳定为目标的地域空间整体对自然和社会扰动的吸收、复原或转化能力,为人地系统研究中针对性理论模式和可定量化指标体系的塑造提供新途径。本文以从自然维度出发的政策与生态系统空间恢复力、从社会维度出发的环境变化与社区生产生活空间恢复力、从综合描述方式出发的空间恢复力综合指标体系三个角度梳理空间恢复力研究现状,并从结构、功能、阈值三个方面研讨不同地域功能类型下的空间恢复力指标体系,提出认知保障系统可持续性的空间状态、明晰人地系统动态过程的空间阈值、满足生态保护与社会进步国家需求三项内容可以作为人地系统动态研究的重要方向。

The concept of human-earth system represents a dynamic structure formed by the interaction between human and earth within a specific region.Considering the complexity of the system,it is necessary to construct a more powerful indicator system to describe the interaction and reflection processes between human and earth systems.The term of spatial resilience can be understood as the overall ability of regional space to absorb,recover or transform natural and social disturbances.Spatial resilience targeted at securing the structural stability of human-earth system,and it also provides a new approach for the shaping of targeted theoretical models and quantifiable indicator system in the study of human-earth system.This study reviews the research progress of spatial resilience from three perspectives,including:ecological policy and ecosystems spatial resilience from a natural perspective;environmental changes and spatial resilience of community production and living from a social perspective and the spatial resilience integrated indicator system from a comprehensive description perspective.Then the article puts forward three important directions of spatial resilience research in China,including understanding the spatial state that guaranteed system sustainability,identifying the spatial thresholds of human-earth system dynamic process,and satisfying the national demands of ecological protection and social development.This study also discusses the spatial resilience indicator system in various human-earth system functional areas from aspects of system structure,function and threshold.By the deepening of the theories and methods of spatial resilience,the human-earth system dynamics can be further understood,so as to improve the regional level accuracy on simulating the socioeconomic,environmental and political paths,and provide key theoretical and methodological support for the decisionmaking of sustainable development at global,national and regional levels.
