村镇建设资源环境承载力测算的基本逻辑与框架

    Basic Logic and Framework of the Calculation of Resources and Environment Carrying Capacity of Rural and Township Development

    • 摘要: 中国不少村镇出现非农化、老弱化、空废化、污损化、贫困化("五化")现象,其实质是村镇建设与资源环境承载力不协调的问题,尤其在实施乡村振兴战略的背景下,大量生产要素投向农村带来发展的同时让这种矛盾日益突出。由于缺少管理上可操作的村镇关键资源环境约束与胁迫因子的精准核算,在村镇发展规模、模式和发展方向路径选择上缺乏依据和标准。该文界定了村镇建设资源环境承载力概念,开展了村镇建设资源环境区划与功能类型划分,设计了村镇建设水、土地、生态关键约束因子及阈值测算原理,建立了村镇建设资源环境承载力综合测算逻辑框架,并提出了村镇建设资源环境承载力研究的关键问题及展望。

       

      Abstract: Many villages and townships in China have shown the phenomenon of "five Changes" (non-agriculturalization of economy, population aging, empty and desolation, pollution, and impoverishment). There is a problem of disharmony occurred between the development of rural and townships and the carrying capacity of resources and environment. Especially, in the context of the implementation of the Rural Revitalization Strategy, a large number of production elements will be invested in the countryside, so this contradiction would become increasingly prominent. On the other hand, there is a lack of accurate accounting of key resources and environmental constraints and stress factors at the operational level in the management, and there is also a lack of basis for implementing the rural and township development mode and development direction. In this paper, the concept and research progress of resources and environment carrying capacity of rural and township development are defined; the resource and environment division and function type division of rural and township development are carried out; the key constraint factors and threshold calculation principle of water, land and ecology of rural and township development are developed; the comprehensive calculation logic framework of resource and environment carrying capacity of rural and township development are formed, and the key issues and prospects of research on resource and environment carrying capacity of rural and township development are finally pointed out.
