    摘要:

    [目的] 计算住宅小区海绵改造后对降雨径流的调控效益,旨在为海绵城市建设提供技术参考。[方法] 结合宁夏回族自治区固原市某住宅小区各低影响开发(low impact development,LID)设施的布设情况,计算不同设计降雨量下LID设施对降雨径流的截蓄量与各LID设施截蓄容积的利用率;再结合固原市2004-2014年的降雨资料,计算出该小区年均降雨径流总截蓄量与各LID措施对降雨径流的截蓄量。基于计算出的小区LID设施对降雨径流的截蓄数据,结合资源环境经济学原理,计算小区降雨径流年调控效益、单方降雨径流调控效益与各LID措施年均降雨径流调控效益。[结果] 小区海绵改建后,年均降雨径流调蓄量增加11 568 m3,产生的效益为111 302元/a,单方降雨径流调控效益为9.62元/m3;各LID设施年均效益分别为:雨水花园45 273元/a,下沉式绿地27 103元/a,雨水桶6 654元/a,雨水池32 272元/a。[结论] 住宅小区海绵改建能够有效控制小区降雨径流的外排量,提高小区年径流总量控制率,具有明显的经济、环境和社会效益。

    Abstract:

    [Objective] The regulation and control benefits of rainfall-runoff after sponge reconstruction in residential districts were calculated to provide a technical reference for sponge city construction.[Methods] The interception capacity of rainfall-runoff and the utilization rate of low impact development (LID) facilities was calculated under different rainfall intensities, based on LID facilities in a residential district of Guyuan City, Ningxia Hui Autonomous Region. The total annual rainfall-runoff interception capacity and the rainfall-runoff interception capacity of each LID were measured using the rainfall data of Guyuan City from 2004 to 2014. The annual rainfall-runoff control benefit of each LID was determined using the calculated rainfall-runoff interception and storage capacity data of LID facilities, the resource and environment economics, the annual regulation benefit, and the unilateral rainfall-runoff control benefit.[Results] After sponge reconstruction, the average annual rainfall-runoff storage increased by 11 568 m3, the benefit was 111 302 yuan per year, and the benefit of unilateral rainfall-runoff control was 9.62 yuan/m3. The average annual benefits for each LID facility were 45 273 yuan per year for a rain water garden, 27 103 yuan per year for a sunken green space, 6 654 yuan per year for a rain water bucket, and 32 272 yuan per year for a rain pool.[Conclusion] Sponge reconstruction in residential areas can effectively control the external displacement of rainfall-runoff and improve the total annual runoff control rate, which has economic, environmental, and social benefits.
