Study On Ecological Landscape Planning Design Of City Wetland Park In River Type

Wetland is one of the origins of human civilization, is one of the ecological landscape with an independent ecosystem, is also an important part of urban green space system, wetland is a unique ecological system which is formed by the interaction of water and land. With the acceleration of the urbanization process, many-storied buildings have sprung up, the expansion and reconstruction of the city lead to rapid reduction of wetland area in the city. In order to protect the ecological environment of urban wetland, at the same time, creating a space for recreation and educational base, we have a rapid development on the construction of Urban Wetland Park in China in recent years.China is a country of many rivers and mountains. Rivers are mainly concentrated in the basin of Yangtze River, the Yellow River River, Pearl River, Songhua River and Liaohe River… Rivers have change the role effect on the city nowadays. Rivers provide drinking water sources, farmland irrigation, military defense, transportation since ancient times transform into the provision of water, farmland irrigation, recreation and ecological protection. According to the different base characteristics of the Urban Wetland Park in China, we classify into four types: "river type", "lake type", "coastal type", "farmland type". Among the most accessing to the city’s distance is Urban Wetland Park in river type, such as: Zhengzhou, Wuhan, Chongqing, Nanjing, Harbin, Tsitsihar and other cities. All of them have rivers through the middle of city. Therefore, the river typological city wetland park is the most closely related to the whole ecological environment of the city, and the construction of its research will process the most direct and quick response to the whole ecological environment of the city.Due to the difference of climate between south and north of China, City Wetland Park construction in south is relatively backward than southern cities, and the number of the river typological city wetland park in the north is far more than the other types of Wetland Park, so it is very important to study the ecological landscape design of the river typological city wetland park in the north.The construction of Wetland Park in China looks like a raging fire, and many problems emerge in the construction process, For example: Urban Wetland Park have no clear positioning, the lack of ecological protection, plant configuration, etc.. These questions have not only protected the wetland, but also may cause the city wetland park to twice damage, therefore we should adopt the scientific method on the city wetland park, to protect, restore and reconstruct.This paper will take the "river type city wetland park" as the main research direction, from the three aspects of ecological space planning, landscape space design and park use function to elaborate. And use a large number of comparative analysis from domestic and foreign cases to search the shortage of China’s urban wetland park in river type. Then discuss these problems and propose solutions on River Wetland park in order to study the reasonable and feasible design method.
