| 摘要: |
| 山地小城镇的地形地貌复杂多变，雨洪灾害特征呈现出特有属性，其发生机理涉及多尺度、多地域的要素影响。基于城市韧性与海绵城市等理论研究，构建山地小城镇雨洪管理模式，采用定量化、可视化的模拟分析方法，从宏观（市域）、中观（镇域）、微观（场地）3个空间尺度，层层递进地探究科学有效的雨洪调控方法。依次选取四川省彭州市、彭州市湔江龙门山镇河段、龙门山镇场镇作为研究对象，分别运用ArcGIS构建宏观尺度海绵生态安全格局、采用SWAT重构中观尺度汇水网络结构、借助SWMM实践微观尺度海绵设施调控。研究结果验证了各尺度空间基于软件模型模拟调控雨洪的可行性，并提出多尺度防洪防涝生态策略，对山地小城镇的雨洪管理体系构建提供了重要的参考和启示。 |

| Abstract: |
| The terrain and landform of small towns in mountainous regions are complex and changeable, and the characteristics of stormwater disasters show unique attributes. The occurrence mechanism involves multi-scale and multi-regional factors. Based on the urban resilience and sponge city theoretical studies, this research uses the quantitative and visual simulation analysis method, and from the macro-scale (city), meso-scale (town) and micro-scale (site), to explore scientific and effective methods of stormwater management. It successively selects Pengzhou in Sichuan, Longmenshan Town in Pengzhou, and the central space of Longmenshan Town as the research objects. The macro-scale sponge ecological security pattern is constructed through ArcGIS, the meso-scale water system structure is reconstructed through SWAT, and the micro-scale sponge facility regulation is implemented through SWMM. Based on software models in spaces at various scale, the results of the research have verified the feasibility of simulating rain and flood control, and have proposed multi-scale ecological strategies for flood and waterlogging prevention, which provides important reference and enlightenment for the construction of rain and flood management system in small mountain towns. |
