Primary Exploration Of The Urban Wetland Park's Landscape Design

Urban wetland as a important part of city ecosystem has many functions such as flood control, anti-drought, adjust local weather, accumulating the headwaters, maintain the natural biological diversity and so on. Summarizes the relevant theoretical knowledge and practical research achievements, utilizes science and ecological principles to find out practical problems. A lot of collection of information and in-depth field survey make it more scientific and practical, provide scientific basis for its research results. Has important meaning to improve the level of the development of the urban wetland park.Through Hangzhou Xixi wetland park and Chengdu Huoshui park's present situation research, strive to resolve the following question:how to protect and rational utilize wetland resources, how to make the plant theme of the urban wetland park and its ecological diversity prominent, how to grow aquatic plants in the serious pollution water to purify the water.Combined with the Yanghuyuan wetland park stage1project's existent problem, this paper put forward a novel design concept which is building a farming type urban wetland park base on fundamental principle "ecological" and "culture" to achieve the human and the nature's harmonious coexistence. Finally take Changsha Yuanhuyuan wetland park for example, evaluates its plan, put forward the existing plan should improve the following:(1) Urban wetland has certain requirements in geographical location and area, complex ecological elements and strong sensitivity etc. So in the city wetland park design, we should be scientific and cautious, should banlance protection and utilization, utilize wetland resources to the greatest extent.(2) The investigation of Yanghuyuan wetland park shows that the matching of some plants is not reasonable, aquatic plants species are too few; and large area water lead to Luan tree, sweet camphor tree being drowned. This paper propose increasing the aquatic plants to rich the landscape of plant, and building reasonable drainage to avoid trees were drowned by water. As the theory of urban wetland park construction is not mature, and design theory is not perfect, so this article only do preliminary discussion, i hope it can be helpful on the city wetland park landscape design and construction.
