The Research On The Hierarchical Size Structure Of Mordern Garden City

In recent years, urban developed rapidly due to the progress of urbanization. At the same time,problems in urban and rural are increasingly serious.Including gap between urban and rural development, serious The pollution of urban environment, urban traffic congestion and high cost of city life.The emergence of these problems make people urgently need a city with beautiful environment,convenient transportation,facilities and reasonable size. Modern garden city is the ideal city meet these requirements. So far,the theory of modern garden city and build our country is still in the exploratory stage, has not yet formed a complete system.So far,the theory of modern garden city is still in the exploratory stage,has not yet formed a complete system. At the same time, the theory of modern garden city lack of guidance practice specific methods of operation.In this paper, the hierarchical size structure of modern garden city were studied.First of all, parsing the modern theory of garden city.By analyzing the construction background of modern garden city, developing modern rural development goals of the city. At the same time, definiting the concept of modern garden city. After analyzing the influence factors of the hierarchical size structure of modern garden city,clearing research idea for studying the modern hierarchical size structure of modern garden city.According to the urban function factord,determing the function of modern garden city plate division and concluding the hierarchy of modern garden city.Then combined with the public service facilities, reasonable radius of production factors and population threshold of all levels of public service facilities,calculating the modern rural urban size.Finally concluding the modern rural the hierarchical size structure of the city.This article mainly has the following conclusion:(1) Modern garden cities owe good ecological matrix for the basement with group, networked, polycentric urban and rural spatial form. With economic integration of urban and rural industry, urban and rural social function integration, integration of urban and rural ecological network, urban and rural traffic network model for urban and rural development. Modem garden cities has a clear division of responsibilities classification of fine social urban functions and are composed of multi-level urban and rural group town group.(2) Analysing the influence factors of modem rural scale structure of city grading.The main influence factors including modem rural cities, the public service facilities, reasonable distribution of population density, radius of production.(3) Determine the level of modem garden city scale structure:Garden city—The beautiful small town—Rural communitie.Rural service population size in range of 50000-100000. The beautiful small town service population size in the range of 10000-50000. Rural community service population size in the range of 3000-10000.If the beautiful small town services three rural communities (9000 people), the population of township of the beautiful small town is 1000 people. If the beautiful small town services two rural communities (6000 people), the population of township of the beautiful small town is 4000 people. If the garden city services three rural communities (30000 people), the population of township of the beautiful small town is 20000 people. If the garden city services three rural communities (40000 people), the population of township of the beautiful small town is 10000 people.(4) Determine the level of Jinghe city scale structure:Garden city—The beautiful small town—Rural communitie. Rural service population size in range of 50000-100000. The beautiful small town service population size in the range of 16639-50000. Rural community service population size in the range of 3327-10000.
