摘　　要：因其特殊的混凝土河道,洛杉矶河可能是世界上最具辨识度的河流之一。随着洛杉矶地区的城市化逐渐推进,这条河流为降低洪水发生风险而被渠化,在一些人眼中,这是建筑工程史上的丰功伟绩,而在另一些人眼中则是一场生态灾难。洛杉矶河流经17个城市,其中不乏洛杉矶县境内环境最恶劣、公园最稀缺、服务水平最差的一些社区。在河道的通行权范围内有超过930多公顷的公共用地可以用来重塑洛杉矶河,这将会影响河道周围1.6km范围内100万人的生活。洛杉矶河总体规划由洛杉矶县主导,计划于2021年秋季完成。该规划提议建设长约51英里(约82km)相互连接的公共开放空间,其中包括一系列多效益项目,共响应了9个总体目标,从防洪韧性到房屋经济实用性,再到生态功能、艺术、教育和文化等。在这一面向未来25年的基于数据的规划中,进行了一项针对全流域的研究,致力于记录和理解与环境和社会问题相关的水质、水源地保护与洪水风险的话题。规划还提出了兼具传统与创新策略的"工具包",配置了栖息地桥梁、干旱河谷侧渠等在内的65种设计工具,旨在提升生态系统服务、形成一个欣欣向荣的城市居所和相互连接的滨河公园网络。The concrete channel of the Los Angeles(LA)River is probably one of the most recognizable rivers in the world.Channelized to manage the risk of flooding as the Los Angeles region urbanized,the river today is an architectural and engineering feat in the eyes of some people but an ecological disaster to others.The river flows adjacent to 17 cities and among some of the most environmentally burdened,park poor,and underserved communities of LA County.With over 2,300 acres of largely publicly owned land within the river right-of-way,a reimagined LA River can impact the lives of the one million people that live within a mile of the river.The LA River Master Plan,led by Los Angeles County and scheduled to be completed in fall 2021,proposes 51 miles of connected public open space with multibenefit projects supporting nine goals ranging from flood resilience to housing affordability,to ecological function,and to arts,education,and culture.The data-based plan for the next 25 years includes a watershed-wide research effort to document and understand water quality,water conservation,and flood risk in relation to environmental and social issues.The plan includes traditional and innovative strategies within a"kit of parts,"interventions that include over 65 components ranging from habitat bridges to dry arroyo side channels demonstrating opportunities for enhancing ecosystem services to create a thriving urban habitat and connected network of parks along the river.
