Research On The Planning And Construction Of Town Green Infrastructure In Zhengzhou

On the basis of construction of cities and towns green space in Zhengzhou city and domestic research results of ecology,geography,economics and other related fields,the paper investigates the application of the theory of green infrastructure in the green space construction of cities and towns in Zhengzhou city,using literature research,field research,discipline integration,GIS analysis and other methods.According to topography and administrative divisions,towns of Zhengzhou city are divided into two types that are "mountain town" and "plain town".Then on the basis of investigation,the research makes a thorough discussion on their advantages and disadvantages,and proposes the strategies of the green infrastructure for the two types of urban landscape features respectively.From the theoretical perspective,the research focuses on town domain instead of city domain,hoping to make a contribution to the improvement of our country's green infrastructure theory,and improve the process of urban green ecological construction continuously in practice.In fact,the green infrastructure has gradually become a life support system in the development of China.From the perspective of practice,the research trys to apply the advanced research at home and abroad to the green space construction of cities and towns in Zhengzhou City.At the same time,the paper combines the green space construction of Xinmi Daweizhen with green infrastructure,using special use of Envi,Arc GIS and landscape pattern analysis software Fragstats.The practice trys to make an improvement to the current landscape situation,alleviating the main contradiction in the construction and providing reference for ecological construction in other towns.The main contents of this paper include the following aspects.1.The investigation and analysis of the status quo of the green space in Zhengzhou City,and the induction the outstanding problems in the construction of urban green space in Zhengzhou,providing the basis for the analysis and planning of the latter;2.The summary and analysis of the general theory and method of green infrastructure construction in the basis of domestic and international research,making a clear explaination of the urban green infrastructure construction in Zhengzhou city;3.Dividing towns of Zhengzhou city into two types,"mountain town" and "plain town",according to topography and administrative divisions.Proposing the strategies of the green infrastructure for the two types of urban landscape features respectively;4.Taking Xinmi Daweizhen as an example,making a clear explaination of the of the green infrastructure construction process.Putting forward to some strategies to provide a basis for solving the problems in urban green space construction.
