Study On Ecological Restoration Of Urban River Wetland Park

Ecological restoration is a science that studies the process of ecological restoration and management,which has become a popular subject.City river is the birthplace of a city,with the city's construction and development,the ecological restoration project in city river gradually rise,wetland park construction is an important method for the healthy development of the river of the city.Through the implementation of ecological restoration measures of city river wetland type,can effectively solve the contradiction between the river space,wetland animals and plants and the city,to build eco city comprehensive leisure place.This paper from the contradiction of the city expansion and updating,river water pollution exacerbating,problem of city waterlogging and sponge city construction contradiction,the contradiction between rapid development of city wetland park and wetland resources environmental degradation trend these three overall background,from the perspective of ecological restoration,ecological restoration based on landscape ecology,ecological design,culture and design sponge the city's theoretical basis,using the methods of literature research,case analysis,on-the-spot investigation,multidisciplinary research methods and basic theoretical research at home and abroad,analysis ecological characteristics of City River Wetland Park,including the diversity of ecological functions,the dual nature of spatial structure,the internal and external environment and the diversity of the contents these four major characteristics,the general idea of ecological restoration of City River Wetland Park to determine scientific restoration and ecological protection is priority.The overall principle is the following five: integrity,conservation priority,district protection,ecological design,space and time.The overall development goal is human-Wetland-urban sustainable development.The preliminary analysis and summary based on City River Wetland Park four ecological characteristics based on the proposed four strategies for ecological restoration of River Wetland Park Based City: Ecological function diversity of ecological river and optimizing design strategy,based on the spatial structure of double bidirectional continuous rainwater collection strategy,and variability of internal and external environment based on sewage treatment strategy,based on the content rich ecological diversity strategy based on space layout.Finally,the comprehensive application of the four strategies in the Maitreya River Wetland Park in the city of Austin,to solve a series of problems of pollution of river heavy congestion,poor landscape,ecological space,City Development Zone broken power difference,by coordinating the relationship between the three aspects: city ecology,city landscape,city space,activate the comprehensive benefits of city river wetland,wetland park to build a set of ecological,leisure and entertainment,science education for the integration.These four strategies are focused on river ecology,stormwater regulation,pollution control,space layout four aspects,aims to conflicts and waterlogging in the city and river flood drainage function coordination between city development and ecological destruction and the rapid development of city environment and resources is contradiction between the trend of degradation.The ecological restoration of the Wetland Park,with many factors of ecology,landscape,culture and economy to create a balance point between city,parks and rivers ecological.It provides a new way for the construction of Urban River Wetland Park and the sustainable development of wetland environment.
