摘要

摘要: 以固原市玫瑰苑小区为例,根据小区可改造绿地空间充足、雨落管断接改造难度较小等特点,提出了海绵化改造思路及工程内容,并对海绵化改造后的经济效益和生态效益进行核算。结果表明:通过海绵化改造即改造排水系统,建设下沉式绿地、植草沟、雨水花园、雨水罐、蓄水池、透水铺装等措施,可使小区综合雨量径流系数降低0.21,小区雨水径流量减少5 137.85 m ³∕a,具有良好的雨水调蓄效益;海绵化改造后具有一定的经济效益,可节约城市排水设施费用411.03元∕a,节约自来水费用4 159.20元∕a,节水效益达28 155.42元∕a;海绵化改造后可吸碳8.18 t∕a,释放氧气6.31 t∕a,吸收二氧化硫50.73 kg∕a,生态环境效益显著。

Abstract: Taking Rose Community in Guyuan City as an example, the ideas and project contents of the sponge transformation were put forward according to the community characteristics such as large green space area and less difficulty in the renovation of broken rain-falling pipes, and the economic and ecological benefits after the sponge transformation were calculated. The results showed that, by means of the sponge transformation, which was to reconstruct the drainage system and construct the sinking green land, grass ditch, rainwater garden, rainwater tank, reservoir and permeable pavement, etc., the comprehensive rainfall runoff coefficient could be reduced by 0.21 and the runoff reduced by 5 137.85 m ³∕a in the residential area, thus resulting in good effect of rainwater regulation and storage. The sponge transformation had certain economic benefits, which could save the urban drainage facilities cost of 411.03 yuan∕a, the tap water cost of 4 159.20 yuan∕a, and the water-saving benefit of 28 155.42 yuan∕a. After the sponge transformation, it could absorb 8.18 t∕a of carbon, release 6.31 t∕a of oxygen and absorb 50.73 kg∕a of sulfur dioxide, resulting in significant ecological and environmental benefits.
