- 摘要:
- 传统低影响开发(LID)仿真建模通常基于粗略土地分类和水文特征进行平面布设,导致海绵措施无法在竖向立体空间进行精细化布设建模,其协同组合效应对径流控制的影响往往被忽略或低估。为此,提出了一种基于精细土地利用分类和改进式水文表征的竖向LID模型构建方法,通过在LID仿真模型中建立径流连通路径和流量通量计算,实现不同海绵措施径流的相互连接和转移,以进一步进行渗透、储存和运输。研究结果表明,基于竖向布设的海绵措施组合对总出流量和峰值有更高的控制效果,比平面布设下的指标分别降低了12.83%~26.30%和17.14%~21.62%,可为后续海绵城市建设提供新的思路和技术支撑。
- Abstract:
- The traditional simulation modeling of low impact development (LID) is typically based on rough land classification and hydrological characteristics for planar layout, which leads to the inability to conduct refined layout modeling of sponge measures in the vertical three-dimensional space, and the synergistic combination effect on runoff control is frequently ignored or underestimated. Therefore, a vertical LID model construction method based on refined land use classification and enhanced hydrological characterization was proposed. By establishing the connected route of runoff and the calculation of flow flux in the LID simulation model, the interconnection and transfer of runoff from diverse sponge measures were accomplished, thereby facilitating further infiltration, storage and transportation. The combination of sponge measures based on vertical layout exhibited a superior control effect on the total runoff and peak value, being 12.83%-26.30% and 17.14%-21.62% lower than that under the planar layout, and could offer novel ideas and technical support for the subsequent construction of sponge cities.
