摘要:
绿色屋顶是一项重要的海绵城市建设措施，具有能够调控雨水径流、缓解城市热岛效应等功能。由于屋顶的承重能力有限，传统绿色屋顶的基质较薄，保水能力有限，屋顶植物容易因缺水而干枯甚至死亡，极大地影响了其海绵性能，增加了绿色屋顶的运营成本。基于此，选用了一种高吸水性树脂，该树脂吸水性能良好，吸水量可达224 g/g，具有较强的重复利用性和恶劣环境（温度、盐度和pH）抗逆性。在深圳市龙岗区进行的实验表明，将其与绿色屋顶的基质混合使用，能够明显提升绿色屋顶的海绵效能。由于高吸水性树脂的存在，绿色屋顶的成坪速率得以提高，植物的生长状况明显优于无树脂组。在4次降雨中发现，高吸水性树脂能够明显降低绿色屋顶的径流量，最高可降低15.9%。综合其易得性和低价格的优点，高吸水性树脂保水性能良好，能够明显提升绿色屋顶的海绵效能，是一种具有广阔应用推广潜力的绿色屋顶基质改良剂。
Abstract:
Green roof is an important sponge city measure, which can regulate rainwater runoff and alleviate urban heat island effect. Due to the limited load-bearing capacity of the roof, the thickness of the matrix of traditional green roof is thin, and the water retention capacity is limited. In addition, roof plants are prone to dry up or even die due to lack of water, which greatly affects the sponge performance and increases the operational cost of the green roof. Based on this, a polymer which had a good water absorption performance was selected. Its water absorption capacity was 224 g/g, and it had strong reusability and resistance in harsh environment (temperature, salinity and pH). The experimental results in Longgang District of Shenzhen showed that the sponge efficiency of green roof was significantly improved when the polymer was mixed with the matrix of green roof. Due to the presence of super absorbent polymer, the formation rate of green roof was improved, and the growth of plants was significantly better than that of the blank group without polymer. The super absorbent polymer significantly reduced the green roof runoff by up to 15.9% in four rainfall events. Considering the advantages of easy availability and low price, the super absorbent polymer has good water retention performance, and significantly improves the sponge efficiency of green roof, indicating that it is a green roof matrix ameliorant with broad application potential.
