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.
