There is growing awareness in cities all over the world that blue-green infrastructure (BGI) can offer a wide range of ecosystem services that support a healthy urban environment. Green areas, including meadows and river valleys within cities, are useful for short-term water storage. This possibility has become more visible in recent years, as water management is increasingly combined with ecological objectives. However, the potential benefits arising from blue-green infrastructure are most likely only partially exploited due to the lack of a practical understanding of what these benefits are and how best to implement BGI. Therefore, there is a need to translate scientific knowledge of the functionality of BGI into principles for designing the new concept of resilience cities. Another important aspect of the approach to contemporary urban systems is the ‘circular economy’. Sponge City as an element of water-sensitive urban design (WSUD) protects local communities against excessive rainwater runoff and at the same time provides new green jobs. In hydrological terms, large impermeable surfaces contribute to surface runoff, which can lead to soil erosion, deterioration in water quality, the risk of flooding and drought.

河谷恢复景观特征和城市生态系统功能连续性的价值——综述

世界各地的城市越来越意识到蓝绿色基础设施 (BGI) 可以提供支持健康城市环境的广泛生态系统服务。绿地,包括城市内的草地和河谷,可用于短期蓄水。近年来,随着水资源管理越来越多地与生态目标相结合,这种可能性变得更加明显。然而,由于缺乏对这些好处是什么以及如何最好地实施 BGI 的实际理解,蓝绿基础设施带来的潜在好处很可能只得到部分利用。因此,需要将华大基因功能的科学知识转化为设计韧性城市新概念的原则。当代城市系统方法的另一个重要方面是“循环经济”。海绵城市作为水敏城市设计 (WSUD) 的一个元素,可以保护当地社区免受过多雨水径流的影响,同时提供新的绿色就业机会。在水文方面,大面积的不透水表面会导致地表径流,从而导致水土流失、水质恶化、洪水和干旱风险。
