Analysis On The Distribution Of Harbin’s Public Park With Using Gravity Model And Voronoi Graph

Public Park is important part of the city green system which plays the important role for the city. It is important entertainment place for the city people and has the function of culture, leisure, entertainment, ecological. The layout of Public Park is distribution and configuration of the public park in the city land, whose reasonable degree reflects construction and management level of the public park. This passage uses Harbin’s public as object of research subject, uses the layout of Public Park as the target of research, and gives some adjusting suggestion about how the Harbin’s public park should get the further deployment through analysis and evaluating the layout of Harbin’s public park.Firstly, through a lot of literature research, sum up the theory of the layout of the public park, and then analyze this theory.Finally use "Gravity Model" and Voronoi polygon to estimate the service population of the public park. The author use this method combined with the area of the park to estimate the population on unite area of the park.and then analyze the distribution of Harbin’s Public park. Combining with the urban status quo, site investigations and surveys, the author make recommendations on the distribution of Harbin’s Public Park.By the analysis of Voronoi Graph model,"HongWei Park","Shangzhi Park" has larger of service range; the largest one has outstripped2000hectares, the service area of "Hongwei Park "has reached has4,671hectares;"Shangzhi Park", and "Children’s Park",Etc. serve more residents, and service has more city residents, accounting for36%of the total number;, In the service region of "Aijian Square","Changqing Park"etc public park area of capita is small,less than0.2square meters. By analysis of Gravity Model,"Heilongjiang province forest Botanical Garden","Songle Park "will attract more resident up to399,000people. But "Lesong Park" and "mother square" attract less people insufficient20,000people. By using Gravity Model and Voronoi Graph Model, comprehensively consider the serving range of public park and the attractive of the park "Shangzhi Park ","development zone landscape square", every hectares sever lot of people,up to12,000people. These parks need take some measures to reduce the number of visitors in each hectare and relieve."Qunli national wetland park" sever small number of people. Each hectare serves less than hundred people. These parks are often located in the new area of the city and will be more use in the future.Under quantitative research, the service situation of Public Park of daoli district is best,"Shangzhi Park","Development Zone Landscape Square","Taiping Park","Children’s Park", and "Changqing Park" these parks sever large number of people. The number of visitor in every hectare is high. In order to relieve the service pressure of these parks, the author made countermeasures to optimize and develop the distribution of Public Park in Harbin. According to the actual situation, the author select four place to build parks. At last against the status quo of Harbin, the author made four recommendations to distribute Public Park. That is developing different types of parks.;. Improve the management system of the Park. Improve that openness of the park and focused on landscape environmental construction in the construction of other cities.the greenbelt area is smaller, to mitigation the service pressure of these Park, research on the distribution of Public Park in Harbin made optimization and development of countermeasures, under actual research select has Yellow River Park site, around for construction Park of locations, Last Park against the status quo of Harbin park planning proposals, that is, developing different types of parks, improve the management system of the Park, improve parks open and in the construction of other cities is focused on landscape environmental construction of four pieces of advice.Studies have shown that it is a more scientific and reasonable method to estimate the visitors of each park and the scope of services by Gravity model and the Voronoi graph model, through the analysis of these data, it can evaluate the layout of parks by means of the view of service, and put forward the suggestion that to adjust and develop the park layout of Harbin, hope to provide some significative references for the Management Department and the Planning Department.
