  • 摘要

    实现近零生态损害的资源开采、国土空间生态的系统修复,恢复力是关键。尽管一些研究直接或者间接地指出了恢复力的重要性,但目前对矿山土地生态系统恢复力机制的理论认识还很缺乏。构建了一个矿山土地生态系统的非线性动力学模型,利用数值模拟方法来揭示恢复力在矿山土地生态系统中的动力学表现和基本性质,以期为矿山区域国土空间的系统修复和保护提供理论依据。研究结果表明:① 恢复力是矿山土地生态系统的基本属性,是指在有限强度的扰动后,系统具有回复到平衡点、保持原状态和定性结构的能力;② 恢复力产生的原因是系统具有复杂结构,且是自组织的,在面临扰动时表现出自维持能力;③参数变量是决定恢复力大小的重要因素,其阈值空间是测度恢复力的直接指标;④ 恢复力具有可塑性,调控恢复力的基本途径是恢复力强化和克服,关键技术是对参数变量及其阈值、状态-参数变量间关系进行调控。矿山土地生态系统恢复力是一个客观存在的动力学属性,该属性为采矿前土地生态影响评估、采矿中土地生态系统状态维持、采矿后土地生态系统修复和可持续发展提供了基本依据。恢复力可以作为系统保护和修复的核心准则,恢复力思维则是指导土地复垦与生态修复的核心理论之一。未来需要加强对恢复力测度、调控和建设方法的研究,并在与采矿活动和环境保护的具体工程中大力推进恢复力机制的技术应用和集成。

  • Abstract
    Resilience is the key to achieve the goal of the resources exploitation with near-zero ecological damage and the systematic restoration of the land ecosystem. Although few studies have directly or indirectly suggested the impor- tance of resilience,the current theoretical understanding on the resilience mechanism of land ecosystem is still limited. This paper has established a nonlinear dynamic model of land ecosystem in mining area and used the numerical simu- lation to reveal the resilience’s dynamic performance and fundamental properties. This research aims at providing theoretical reference for the systematic protection and restoration of the land ecosystem in mining area. The results show that ① Resilience is the basic property of the land ecosystem. After the disturbance with limited intensity,the system has the ability to return to the equilibrium point,maintain the original state and the qualitative structure;② The cause for the emergence of resilience is that the system has a complex and self-organized structure therefore show a self-sus- taining ability in the face of disturbance;③ The parameter variables are important factors for determining the magni- tude of resilience,and their threshold space are direct indicators of the resilience;④ Resilience has deformability,the basic pathways for regulating resilience are resilience enhancement and overcoming,the key technique is to regulate the relationship among parameter variables and their thresholds and state-parameters variables relationship. The resili- ence of land ecosystem is a dynamic property,which can provide a basis for the ecological impact assessment before mining,the maintenance of land system during mining,the restoration and sustainable development after mining. Resil- ience can be adopted as the core criteria for land ecosystem protection and restoration. Resilience thinking is one of the core theories guiding land reclamation and ecological restoration. In the future,the research on the methods of resili- ence measurement, regulation and building needs to be strengthened. The application and integration of resilience mechanism in specific engineering about mining and environmental protection should be further promoted.
