考虑局域气候影响的海绵城市垂直绿化技术应用

Application of Vertical Greening Technology in Sponge City with Influence of Local Climate

以玉溪市老城片区海绵城市改造为工程背景,分析了玉溪市的局部气候特征,包含年降雨量、年蒸发量、月降雨量、月蒸发量及日照时长等因素,对垂直绿化工程中的植物给出了具体种类及合理种植密度。以玉溪市第二幼儿园的垂直绿化墙为示范案例,运行一年后,经测试,园区绿化区域附近路面平均径流系数由最初的0.9降到了0.86,取得了较好的效果,该工程可为相似气候区域的海绵城市垂直绿化工程提供参考。

This paper analyzed the local climate characteristics of Yuxi based on the reconstruction of sponge city in the old city area of Yuxi, which included annual rainfall, annual evaporation, monthly precipitation, monthly evaporation and sunshine duration. Specific species and reasonable planting density of plants in vertical greening project were decided. According to the case of the vertical greening wall of the second kindergarten in Yuxi, after running for one year, it was found that the average road surface runoff coefficient in the vicinity of the green area decreased from the original 0.9 to 0.86. The conclusion which was summarized in this paper provided reference basis for the vertical greening project of sponge city in similar climate region.
