长江经济带开发与保护空间格局构建及其分析路径

Constructing a spatial pattern of development and protection in the Yangtze River Economic Belt and its analysis

长江流域经济—社会—生态系统完整,是中国国土空间开发最重要的东西轴线,在区域发展总体格局中具有重要战略地位。当下,为应对全球经贸格局重组、国家与区域经济社会转型以及资源环境约束趋紧等新形势,国家提出依托长江黄金水道,构建横贯东西、辐射南北、通江达海、经济高效、生态良好的中国经济新支撑带,这就要求长江经济带形成人口资源环境协调的均衡化开发与保护格局。本文基于"点—轴"、分区式与多中心网络式等空间组织结构,明确空间格局的推演逻辑与思路。进而,在区域差异性分析与空间开发适宜性评价基础上,认为长江经济带需重点构建以"一轴两翼,三区六廊"为主体的开发格局、以"六大片区"为主体的农业发展格局、以"五大屏障"为主体的生态安全格局,并提出不同区域差异化发展导向、路径与制度建议,以及今后长江经济带空间结构需进一步研究的主要科学问题。

The Yangtze River Basin has integrated economic, social, and ecological systems, and is the most important east- west axis of national spatial development of China. It has an important strategic position in the overall pattern of regional development. In response to the new trends of global economy and trade, national and regional socioeconomic transformation, and greater environmental constraints for development at this time, a new economic supporting area relying on the golden waterway of the Yangtze River has been proposed by the Chinese government. This requires a balanced pattern in population, resources, and environment development and protection in this area. Therefore, based on the point- axis, zoning, and multi- center network spatial organization structures, this article discusses how to construct the spatial patterns. Using the results from regional difference analysis and spatial development suitability assessment, the 'one axis and two wings, three zones and six corridors' development pattern, 'six areas' spatial pattern for agriculture, and 'five barriers' for ecological security strategy of the Yangtze River Economic Belt are proposed; recommendations on development orientations, paths, and regulations of the various regions are made; and main scientific issues concerning the spatial pattern of the Yangtze River Economic Belt are raised in this article.
