Research On The Planning Of The Green Space System In The Central Urban Area Of ??small Towns In The Plain Of Northern Henan

Under the guidance of the central government's policy of "ecological civilization construction" and "rural revitalization",China has entered a period of rapid development of urbanization.Henan,as the birthplace of the Central Plains culture,its urbanization speed is also speeding up gradually,Henan's small town green space system construction ushered in the opportunity of development.Since Henan Province has been demarcated several times after the founding of the people's Republic of China,and has been divided into two parts by the Yellow River,it is located at the Qinling-Huaihe demarcation line.Therefore,the geographical difference between the north and the south is great,and there are obvious regional differences in the basis and characteristics of its town planning.This paper takes the small towns in the northern plain of Henan as the research object,starting from the geographical conditions of the northern Henan plain,firstly,it makes a comprehensive analysis of the basic conditions of the planning of the small towns in the northern Henan plain,and sums up its superiority conditions,restrictive factors and historical evolution causes.Secondly,the planning scheme of Huaxian County,Tangyin County and Boai County is selected as the research sample,and the methods of literature review,field investigation and case analysis are used to make a comparative study on the green space system planning of Huaxian County,Tangyin County and Pok'ai County.Based on the concept of ecology,this paper analyzes the planning conditions,natural environment and social environment of the three counties from four aspects: the structure of the green space system,the types of green space functions,the green space greening structure,and the maintenance of the green space at the later stage.This paper summarizes the general characteristics and common problems of green space system planning in three counties..In view of the problems found in the above-mentioned research,this paper puts forward some perfect suggestions,and introduces the concept of spongy city,puts forward the planning idea of urban green net,realizes the dilution of urban density,green homogeneous cover,and replenishes fresh water resources.Improve the air humidity of a variety of environmental benefits.On this basis the green space system planning of Huojia County is simulated and optimized to explore the regional characteristics of green space system planning and to highlight the concept of the times of green space planning.
