规划与景观设计公司SLA事务所与Saunders建筑事务所赢得了针对哥本哈根市中心Hans Tavsens公园和周边区域重新设计的竞赛。竞赛任务是建筑师需提供一份公园和周边街道景观的改造方案，并有利于水文、生物和社会生态系统。获奖方案名叫“纳莱罗布的灵魂”，它通过建立一套与公园匹配的排水系统，重新设计适合公园的径流方向，使其能在洪涝季节起到蓄水泄洪的作用，同时还能净化水源。

Planning and Landscape firm SLA Architects with Saunders Architecture have won an international competition to redesign Hans Tavsens Park and its surrounding area in the central Copenhagen borough ofNørrebro. The competition tasked architects with envisioning a park and streetscape that would benefit the hydrological, biological and social ecosystems of the neighborhood. The winning proposal, titled The Soul of Nørrebro, tackles the challenge by creating a system of drainage areas and an adaptable park designed to redirect runoff and contain and purify water during flood conditions.

由于纳莱罗布地势低洼平坦，又靠近河流，城市经常受到水患的威胁。在暴雨季节，城市主要街道和地下室被淹已成为常态。溢出的雨水直接汇入Peblinge湖（哥本哈根三个不同矩形形状的湖泊之一），使城市街道遍布淤泥和碎屑，情况不容乐观。

为了缓解这一现象，项目将花费1亿4千万丹麦克朗（2千万美元）将Hans Tavsens公园改造成一个巨型蓄水池，届时将能在同一时间容纳一万八千立方米的雨水。雨水在经过自然过滤后，将顺着Korsgade街旁的植被排水系统缓慢流入Peblinge湖。同时，这条路径将为街道提供一个全新的微环境，并成为城市景观的一部分。

Located on relatively flat land and along the water, Nørrebro is particularly susceptible to the effects of heavy rain. During particularly torrential rains, referred to as cloudbursts, flooding of major roads and basements is common. Excess water runs directly into Peblinge Lake, one of Copenhagen’s three distinct rectangular shaped lakes, pulling with it dirt or debris from the street.
To mitigate these issues, the 140 million DKK (20 million US Dollars) proposed design will use Hans Tavsens Park to act as a rainwater catchment basin capable to holding up to 18,000 cubic meters of water at a time. The rainwater will then be naturally filtered as it is slowly led into Peblinge Lake through planted drainage paths located along Korsgade, an existing street. The irrigation paths will provide a new identity and microclimate to the street, becoming a visible part of the cityscape.

新的公园将提供多块运动的场地，并成为雨季的泄洪区域，这里建有喷泉广场和通往邻近公墓的小道。值得注意的是，在暴雨季节运动场地将成为蓄水空间。由于水渠一直通向湖区，它不得不穿越Blagaards学校，这不仅为学校的花园和操场提供灌溉，还能成为学生们的活动场地。而Korsgade街的排水系统将成为街道和人行道之间的的自然屏障，最后汇入湖边的生态区。

The new park will feature courts and fields for a variety of sports that will serve as retention areas during flooding, a fountain, playground and pathways to the adjacent cemetery. As it travels toward the lake, the drainage basin will also pass by Blågaards School, where it will provide irrigation for gardens and playspaces tended to by school classes. Along Korsgade, the drainage ways will serve as a barrier between the road and sidewalk, emptying into a final biotope along the lake edge.

“我们的解决方案建立在为城市创造更多自然空间的基础上，它不仅解决了暴雨期间城市内涝的问题，同时还创造了一系列连续的城市空间，为社区提供自然的体验，为整个哥本哈根提供新的机遇” SLA的合伙人以及该设计的负责人Stig L. Andersson说到。

项目将在2019年开始施工，预计2022年完成。

“Our solution is based on creating a robust city nature that both solves the specific problem of handling torrential rain to avoid flooding, while at the same time creating a new and coherent series of urban spaces that offer stronger social community, greener and more natural experiences and new, creative opportunities for all Copenhageners,” says Stig L. Andersson, partner and design director of SLA.
Construction is set to begin in 2019, with an expected completion date in 2022.
