摘要
为满足居住建筑设计达到GB 50378—2014《绿色建筑评价标准》中"节水与水资源利用"的要求,本文针对夏热冬冷地区城市的气候生态特殊性,利用该地区城市社区内人造湿地作为城市水环境规划研究的一部分,实施人工湿地雨水资源收集处理技术,具有成本低、能耗小、运行维护简单等特点。该项研究既能促进雨水的利用,又不以牺牲社区水景观为代价,满足建筑全生命周期内最大限度节约资源,提高绿色建筑节水率和非传统水源利用率,缓解城市热岛效应,有利于保护城市空气、增加植物生长空间、降污除尘,提高城市宜居性的水环境规划策略之一,帮助建筑设计项目以低成本获得更高的绿色建筑星级评价。
Cities in the hot-summer and cold-winter zone in China are now under pressure of declining water resources and aggravating urban environment. Moreover, they are confronted with issues of the fragile urban wetland. Therefore, planners are developing measures such as using constructed wetland to improve urban water environment especially in hot-summer and cold-winter zone. The constructed wetland not only corresponds to requests of GB 50378--2014, but also fits for the special climate of hot-summer and cold-winter zone. The use of constructed wetland can promote the rainwater use rate without the replacement of community water landscape. Furthermore, the artificial wetland can save most resources during a building＇s whole lifecycle and in the meantime improve the green building water-saving rate and nontraditional water use rate. In addition, constructed wetland in communities will be beneficial to urban air, vegetation, and water protection. The construction of artificial wetland can also decelerate the urban heat island effect and then advance the urban livability.
