Research On The Green Space Layout Of Parks In Luoyang Central Urban District Based On Space Syntax And Landscape Pattern

As an important and integral part of the urban green space system,the green space of parks in cities plays an important role in improving the urban ecological environment and the living environment of the residents,meanwhile,it is also an important leisure and recreation site for urban residents.With the rapid development of the city,the gradual increasing of urban population and the constant improvement of the living standards of urban residents,whether the green space layout of parks is reasonable or not,whether the residents are able to access to it quickly or not have become an important index to evaluate the living environment of urban residents.The green space of parks in cities is the leisure space with the highest utilization rate among residents.Only the service radius of green space of parks is taken into consideration in the planning of the green space of parks previously,the time the residents spend to get to the parks and the traffic situation around the parks are ignored.Presently,the evaluation index of green space of parks mainly highlights the rate of green space,per capita park area and so on which are only the statistics index in this regard.Ultimately,the reasonability of the green space layout of parks,whether the urban residents can easily get to the parks or not and the ecological linkage of parks are not taken into consideration,moreover,the qualitative and quantitative analysis and evaluation on the parks are in shortage.The paper takes the green space of parks in Luoyang central urban district as the research object to analyze the green space layout of parks in Luoyang central urban district based on the landscape patterns as space syntax and landscape ecology.It mainly carries out research in the following aspects: firstly,it combs and sorts out the research method and theory according to the research content and makes clear the basic concepts involved in the study,the related theories of research and the methods.Secondly,it sorts out the basic situation of Luoyang,the spatial structure characteristics of the central district,the basic information for green space of parks in central district for follow-up research.Thirdly,the paper analyzes the overall accessibility,the partial accessibility,the permeability of green space of parks in Luoyang central urban district and evaluate whether the green space of parks is reasonable or not in terms of the spatial layout in the central urban district and the linkage between the service capacity of green space of parks and the urban spatial layout by using topological space syntax analysis method,drawing the graph axes model of Luoyang and calculating the overall integration of the relevant variables,the partial integration and the selectivity.Fourthly,the paper evaluates whether the proportion of patch types of green space of park in Luoyang central urban district is reasonable or not,whether the layout of patch types of green space is balanced or not by referring to the landscape pattern correlation index in landscape ecology-landscape fragmentation index,landscape diversity index,landscape dominance index andlandscape evenness index.Finally,the paper summarizes the analysis results obtained by using the two methods: puts forward the advantages and disadvantages of the layout of green space in Luoyang central urban district,as well as some suggestions for optimization.
