        以重大战略通道为主的网络化国土空间格局是构建“双循环”新发展格局的重要支撑。业已形成的“两横三纵”重大战略通道能够有效促进经济社会要素向主要城市群地区集聚。但是，以南北联通为主的纵向战略通道与东西向经济社会联系及交通通道等不匹配、不协同；同时，还存在京津冀城市群横向支撑不足、陆海通道横向带动作用较弱、与对外通道衔接不够等问题。未来应构建“三横三纵”重大战略通道，实现国内战略通道与对外通道融合，加强横贯中西的横向战略通道建设，发挥好沿海城市群对中西部的带动作用，支撑主体功能区战略优化，形成网络化陆域空间格局。

        A networked territorial spatial pattern, centered around major strategic corridors, plays a crucial role in supporting the construction of the new dual-circulation development pattern. The “Two Horizontals and Three Verticals” major strategic corridors that have been formed can effectively promote the concentration of socio-economic factors in major urban agglomerations. However, there exists a mismatch between the north-south vertical strategic corridors and the east-west socio-economic linkages and transportation corridors. Besides, the existing strategic corridors lack sufficient horizontal support for the Beijing-Tianjin-Hebei urban agglomeration, and the land and sea corridors exhibit weak horizontal driving effect and insufficient connection with external corridors. “Three Horizontals and Three Verticals” major strategic corridors should be constructed to realize the integration of domestic strategic corridors and external corridors, to utilize coastal city clusters as a driving force for central and western China, and to support the optimization of the functional zoning strategy.
