摘要:

近年来愈发频繁的洪涝灾害暴露出城市建设与雨洪安全之间的矛盾已不容忽视,以防洪基础设施为核心的防灾规划和以各类景观生态基础设施为核心的海绵城市规划,需要内涵和方法的转变。以“多规协同”为理论基础,提出在国土空间规划背景下,雨洪安全格局构建的核心内涵应该是“协同关系”的构建,即不同规划要素之间不仅在空间布局上协调无冲突,更重要的是能够导向同一的目标与结果。基于该内涵,提出了国土空间雨洪安全格局构建方法的理论框架,应以雨洪安全要素的识别为前提,通过强制性约束措施和引导性联动措施构建雨洪安全要素与国土空间结构、资源用途和支撑系统的协同关系,最终实现不同空间尺度上雨洪安全目标的落实与格局的形成。为更好地诠释该理论框架,以江西省万载县城关镇镇域国土空间规划为案例,探索并检验该理论框架在实践中的可操作性及应用价值,以期为落实国土空间雨洪安全格局的目标提供新的思路和理论依据。

Abstract:

The increasing frequency of flood hazards in recent years highlighted the contradiction between urban construction and flood control. It is important to re-examine the core principles and methods of disaster prevention planning that focused on flood prevention infrastructure and sponge city planning for landscape ecological infrastructure. This paper proposes that, in the context of territorial spatial planning, the core principle of rainstorm flood safety pattern should be "policy integration". The integrated policies do not conflict in spatial layout, but lead to the same goal and result. Based on this core principle we proposed a theoretical framework of rainstorm flood control pattern in land space. Under this framework, the identification of stormwater control elements is the prerequisite, and the key approach is to establish an integrated relationship between stormwater safety elements and land use spatial structure, resource use, and infrastructure systems through controlling measures and guiding measures. This study aims at realizing the safety goals and forming spatial patterns on different spatial scales. To better interpret the theoretical framework, this paper takes the Zhenguan town, Wanzai county, Jiangxi province as a case study to explore and test the operationality and application value of the theoretical framework in practice. This research provides a new perspective and theoretical basis to achieve flood safety pattern.
