【摘要】 本研究聚焦于中国深汕特别合作区的水城格局,探讨了从区域尺度转向流域尺度的海绵城市建设策略,并从合作区面临的挑战出发,尝试将流域空间建设要素与海绵城市相关控制指标进行关联对应,为合作区未来的开发建设提供刚性准则,以确保整个流域的健康与安全。在水城格局的具体构建中,本研究详细讨论了海绵系统布局、城市水系规划、土地开发模式三个方面的策略,通过高标准践行生态保育原则提升全域生态资源占比,通过加密水网、蓄泄兼筹防御风险保障安全,通过岛式开发、河滩利用、湖库保留、坑塘拓展实现资源调蓄以带动土地开发的均衡发展。在合作区即将进入高速发展之际,本方案通过研究合作区水城关系构建策略,探讨了通过流域尺度的海绵城市建设促进绿色可持续发展的创新思路。更多还原

【Abstract】 This article focuses on the water-city pattern development in the ShenShan Special Cooperation Zone in China and discusses the watershed-based sponge city construction strategy.Specific to the challenges of the zone,this study attempts to establish the correspondence between watershed spatial construction and the control indicators of sponge city,providing rigid norms for future urban development to ensure the safety and health of the whole watershed.At a practical level, three strategies of water-city pattern construction are proposed in aspects of 1) sponge system layout,to increase the proportion of the ecological resources across the watershed by a high-level ecosystem conservation;2)urban waterway planning,to protect the zone from floods by increasing the water network density as well as introducing infrastructures for flood storage and discharge;and 3)land development mode,to regulate resources to achieve balanced Land development by dividing the zone into many "islands," taking full advantage of flood plains,reserving the Lakes and reservoirs,and introduce more ponds.As the zone is going to start high-speed development,this article studies strategies of the water-city pattern construction and discusses the innovation methods of promoting sustainable development with sponge city construction at the watershed scale.更多还原
