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.
