国土空间规划中的承载力反思：概念、理论与实践

资源环境承载力是国土空间规划的科学基础和约束条件。通过梳理承载力概念、理论和实践应用的发展,指出其在研究应用中存在概念边界模糊、评价偏向于指标计算、承载力传导机制研究不足等问题。国土空间规划体系改革,以及新时代生产生活和发展方式变革对国土空间规划提出了新的要求。支撑空间规划编制的承载力评价应进一步明确承载力的概念内涵、明晰承载力内在机制、构建承载力评价体系;在实践应用中应当根据国土空间规划和空间治理的新变化新需求,支撑空间规划的新目标、切合空间治理的新模式、顺应空间治理的新手段,为确定国土空间开发利用与保护修复的主要指标、战略部署,以及指标约束传递与地域功能传导等提供科学依据。

Carrying capacity reconsidered in spatial planning: Concepts,methods and applications

Resource and environment carrying capacity is the scientific basis and developing constraints of spatial planning. This paper combs the development of the concept, theory and practical application of carrying capacity, and points out the existing problems in research and application, such as concept's obscurity boundary, evaluation biased index calculation, and insufficient research on carrying capacity transmission mechanism. The reform of the spatial planning system and the changes in production modes, lifestyles and development modes in the new era have put forward new demands on spatial planning. It is necessary to explore and innovate the carrying capacity evaluation which is supporting the spatial planning: (1) Further clarify the conceptual connotation of carrying capacity and form a concept set; (2) Study the internal mechanism of carrying capacity and clarify the formation mechanism of carrying capacity; (3) Construct a multi-space scale, multi-evaluation unit's carrying capacity evaluation system to meet the needs of multi-level spatial planning. In practice, it should provide a scientific basis for determining the main indicators and main tasks of spatial planning according to spatial planning and spatial governance changes, supporting new goals of spatial planning, adapting to new modes of spatial governance, and taking new approaches to spatial governance.
