复杂环境下人工生态水系工程体系设计研究

城市建设中,常常需要建设不同规模、类型的人工水系。在城市中建设人工水系需协同解决水循环、水质保障、水源与退水、水景观打造及极端情况应急预案等多方面问题。以北京未来科技城环形水系设计为例,采用传统水工设计技术与生态水工学、景观生态学相结合的方法,对环形水系的水循环体系、水质保障工程、水源与退水措施与水景观打造进行了综合设计研究,提出了概念性设计方案,解决了城市复杂约束条件下人工生态水系设计问题,为城市生态人工设计提供了借鉴。研究认为:城市复杂环境下人工生态水系设计需基于传统水工设计技术,有机融入生态水工学及景观生态学方法进行;水循环、水质、水源与退水、景观与生态成为城市人工水系设计的基本内容。

Design and research on system of water engineering of artificial ecology under condition of complicated environment

It is necessary to build different scales and types of artificial canal systems in the process of urban construction. The problems such as water flow system, water quality guarantee system, source and recession of water, landscape of the system and contingency plan should be solved with the artificial canal systems in the urban construction.Taking the water flow system of future science city as an example,the paper used the method of combining traditional hydraulic structure design technology with eco-hydraulic engineering and landscape ecology to design water cycle system,water quality guarantee project, measures of water source and recession, landscape, and propose a conceptual design scheme.The mothod solved the design of artificial urban ecology.Result showed that the design of artificial ecological canal system under the condition of complicated environment should be based on the combination of hydraulic structure design technology, eco-hydraulic engineering and landscape ecology. The design of artificial ecological canal system should includeare water flow system, water quality guarantee system, water source and recession, landscape and ecology.
