Urban water managers face numerous challenges, including limited natural resources for maintenance of technical infrastructure, changing demography, and dramatic environmental degradation. Although the vision of the “water-sensitive city” helps to develop tools and strategies toward more sustainable urban water systems, it does not consider biodiversity effects. We therefore aimed to determine habitat provision or habitat services provided by important rainwater management measures (e.g., ponds, swales, rain gardens, green roofs, green walls, permeable pavement), and to highlight how specific design and management practices for such measures enhance urban biodiversity. There is evidence of habitat services provided by rainwater management measures. Nevertheless, the categorization of such measures as civil engineering structures and their related rules limit efforts to optimize the biodiversity friendliness of design and management. The main factors to provide enhanced and more sustainable habitats are shaping design and maintenance according to target species and favoring connectivity by integrating rainwater management measures into the urban blue-green network. We find that strategic implementation of combinations of rainwater management measures into existing built-up areas allows greater multifunctionality of urban infrastructure. The “biodiversity-friendly and water-sensitive city” implies the efficient integration of ecological design measures in urban planning at building, neighborhood, and landscape scales.

对水敏感的城市满足生物多样性:高度城市化景观中雨水管理措施的栖息地服务

城市水管理者面临众多挑战,包括用于维护技术基础设施的有限自然资源,不断变化的人口统计学以及严重的环境恶化。尽管“水敏感城市”的愿景有助于开发工具和策略,以实现更具可持续性的城市供水系统,但并未考虑生物多样性的影响。因此,我们旨在确定重要的雨水管理措施(例如池塘,沼泽,雨水花园,绿色屋顶,绿色墙壁,可渗透的人行道)提供的栖息地提供或栖息地服务,并着重强调此类措施的具体设计和管理实践如何改善城市环境生物多样性。有证据表明雨水管理措施可以提供栖息地服务。尽管如此,土木工程结构及其相关规则等措施的分类限制了优化设计和管理的生物多样性友好性的努力。提供改善和可持续发展的栖息地的主要因素是根据目标物种进行设计和维护,并通过将雨水管理措施整合到城市蓝绿色网络中来促进连通性。我们发现,将雨水管理措施组合到现有建成区中的战略实施,可以使城市基础设施具有更大的多功能性。“生物多样性友好型和水敏感型城市”意味着在建筑,邻里和景观尺度上将生态设计措施有效整合到城市规划中。提供改善和可持续发展的栖息地的主要因素是根据目标物种进行设计和维护,并通过将雨水管理措施整合到城市蓝绿色网络中来促进连通性。我们发现,将雨水管理措施组合到现有建成区中的战略实施,可以使城市基础设施具有更大的多功能性。“生物多样性友好型和水敏感型城市”意味着在建筑,邻里和景观尺度上将生态设计措施有效整合到城市规划中。提供改善和可持续发展的栖息地的主要因素是根据目标物种进行设计和维护,并通过将雨水管理措施整合到城市蓝绿色网络中来促进连通性。我们发现,将雨水管理措施组合到现有建成区中的战略实施,可以使城市基础设施具有更大的多功能性。“生物多样性友好型和水敏感型城市”意味着在建筑,邻里和景观尺度上将生态设计措施有效整合到城市规划中。我们发现,将雨水管理措施组合到现有建成区中的战略实施,可以使城市基础设施具有更大的多功能性。“生物多样性友好型和水敏感型城市”意味着在建筑,邻里和景观尺度上将生态设计措施有效整合到城市规划中。我们发现,将雨水管理措施组合到现有建成区中的战略实施,可以使城市基础设施具有更大的多功能性。“生物多样性友好型和水敏感型城市”意味着在建筑,邻里和景观尺度上将生态设计措施有效整合到城市规划中。
