Urban Wetland Park Planning Based On The Concept Of Green Infrastructure

With the improvement of human environmental awareness and the concept of building an eco-friendly City,the demand for the construction of eco-environmental infrastructure network system is increasingly urgent.At present,some experts and scholars separate the Green Infrastructure from the traditional ecological infrastructure network facilities and put it into a new kind of infrastructure.Compared with the traditional gray infrastructure,Green Infrastructure can replace some functions of gray infrastructure to a certain extent.Reasonable layout planning can effectively reduce the damage to nature and save the national public resource investment.As an interconnected network system,Green Infrastructure has stability and connectivity,which is beneficial to human use.It is a sustainable development model of green space.At present,experts and scholars in China and abroad have applied the theory of Green Infrastructure to protect the natural ecosystem,and solved environmental problems such as urban rain and flood damage,abnormal climate,and harsh water environment to some extent in urban practice and application.Wetland is one of the most sensitive and abundant ecological areas among all kinds of green land.Wetland parks play an important role in water purification,maintaining biodiversity,reducing climate change,storing flood and discharging,continuing regional culture,providing recreational space,and carrying out scientific research.Starting from the concept of Green Infrastructure,this paper summarizes the attributes,positioning and functions of urban wetland parks under Green Infrastructure by means of literature reading,chart statistics and other methods.On this basis,the specific planning and design strategies under the background of Green Infrastructure are studied from the macro and micro levels.In the planning practice part of this paper,the central city of Hejian in Hejian was selected as the research area for the construction of Green Infrastructure networks,and the green space of the park north of the central city was selected as the specific practical design site for the park of the urban wetlands.Through on-the-spot investigation,photographing,recording and other methods,author investigated the current site conditions,in combination with city planning such as city planning,green space planning,water system construction projects around the city,studied the implementation way of the Wetland Park as a Green Infrastructure city and site scale,how to reasonably place it in the Green Infrastructure network structure,and took this as an example Based on this,the paper further discusses the role of Urban Wetland Park as a Green Infrastructure,and how to maximize its local role to promote the construction of urban green ecological network structure.
