都市型碧道建设背景下的广州市天河区城市河涌绿化管理

Urban River Greening Management of Tianhe District in Guangzhou under the Background of Urban Ecological Belt Construction

都市型碧道作为碧道建设的形式之一,依托都市开放水系提供滨水空间。城市河涌作为城市水系连续开放空间,其绿化管理关系到都市型碧道建设下具有生态、安全、游憩等功能的绿地空间的建设与维护。通过分析都市碧道与城市河涌的功能关系,以天河区河涌为例,研究其分布和水环境治理现状,从生态驳岸处理、硬质河涌岸线的景观处理、植物景观配置3个方面总结河涌绿化景观营造措施,并从分段分级养护管理以及监督与巡查两方面归纳绿化养护管理措施,最后提出河涌绿化管理的原则与思路:应以生态优先,坚持一河一景,注重精细化养护,从而完善河涌绿地功能。

Urban ecological belt is a kind of ecological belt,which relies on river system to provide waterfront space.Urban river is a continuous open space of urban river system,and its greening management is related to the construction and maintenance of ecological,safe and recreational green space under the urban ecological belt construction.This paper analyzes the functional relationship between urban ecological belt and urban river,and takes the rivers in Tianhe District as an example to study the distribution and present situation of water treatment.The paper summarizes the urban river greening landscaping measures from three aspects:the engineering treatment of ecological revetment,the landscape of harden river shorelines and plant landscape.It also summarizes the measures of greening maintenance and management on staged management and supervised inspection.Finally,the principles and ideas of river greening management are put forward to perfect the function of river greening,including ecological priority,different rivers with different scenery and delicate greening maintenance.
