A Study On Urban Tidal Riverfront Green Space Design

River, as the natural corridors of the city, is not only shown the landscape value, but also plays other roles such as social and environmental functions. River is closely bound up with the city’s development and has deeply impact on the spatial pattern, ecosystem stability and the landscape diversity. The rapid expansion of urbanization also alters the nature of the river, and brings a series of ecological environment problems. The construction of urban green system in waterfront is an important part of the urban landscape quality and a significant means to improve the environment and ecosystem stability.For the urban green system in waterfront, this paper adopted the method of combining the theory and case analysis, with other related theory and technology of the river ecological restoration and landscape ecology, to explore how to combine the green system’s landscape features with its advantageous functions, and to solve the problems between the natural process of rivers and the urban development.Tidal rivers as a special type of river which has the normal attributes of the river as well as some unique natural features such as the water back, tidal water level change, and mangrove wetland ecosystem has close and complicated relationship with the surrounding city. The tidal river of Sanya city has been researched based on the theory and technology of the river ecological restoration and landscape ecology in this paper. The design method of the urban green system in waterfront has been studied, and the urban landscape design method of the tidal river in order to reflect regional characteristics of tidal river has been discussed. Finally the balance of the relationship between human activities and river protection is try to find.
