Study On Landscape Pattern And Accessibility Of Urban Green Space

As an important part of urban environment,urban green space plays an important role in improving the quality of living environment and improving the living standards of residents.Accessibility of urban green space is an important index to reflect the level of service.At present,the research on urban green space and its accessibility is mostly aimed at large cities,and the research on the spatial space of small and medium-sized cities is relatively lacking.The characteristics and laws of small and medium-sized urban green spaces and their accessibility are important analysis and research value.Fenghua as a national economy hundred counties,a good level of economic development,but its forest town construction is slightly behind.It is of great practical significance to study the existing problems and study the existing problems of Fenghua green space and its accessibility.Based on the data of Fenghua city road network,this paper analyzes the landscape pattern of urban green space in Fenghua City by means of ArcGIS network analysis function.By studying the gravitational model,this paper studies the urban green space in Fenghua District,Motor vehicle,public transport,driving four kinds of travel under the urban green space in Fenghua built area of the reach ability of the region.The main conclusions are as follows:1.Fenghua urban green space structure is single,urban green landscape structure is very uneven,attached to the absolute advantage of green space,other types of green space accounted for too little.Each of the urban green space,medium-sized green space accounted for a larger advantage,large and medium-sized,relatively large lack of green space.Fenghua area of urban green space complex shape,high degree of fragmentation.2.The distribution of urban green space in Fenghua city showed a "green heart"distribution in the form of agglomeration form.In the south of Jiangkou Development Zone,the northern part of Jinping Street area and the northern part of Yuelin street area formed "green heart" Peripheral,green volume decreased in turn.Fenghua built in the main city that is Jinping Street District,Yuelin Street District and Jiangkou Development Zone,the total amount of urban green space is high,and the urban fringe is Fangqiao Industrial Park,Xiaowangmiao District,Xiwu District,Shangqiao Development Zone Low urban green.3.In the mode of walking mode,the reach ability of urban green space in Fenghua built area is lower than that in urban areas.In the mode of bus travel,the reach ability of urban green space in Fenghua built area is greatly improved.But also improved;in the motor vehicle travel mode,Fenghua built urban green space accessibility as a whole higher.Fenghua built area of the region,can be reached within 15 minutes of urban green space,and 76.17%of the area can be reached within 5 minutes of urban green space.4.Fenghua built urban green space accessibility is uneven,the main city of Jinping Street District,Yuelin Street District and Jiangkou Development Zone accessibility is better,the urban fringe of Xiaowangmiao District,Fangqiao Industrial Park,The reach ability of the Xiwu and shanqiao Development Zone is relatively poor,showing a semi-ring distribution pattern decreasing from the core area to the peripheral area.Each class city inhabitants,in the four modes of travel,are the first grade inhabitants reach ability<the second grade inhabitants reach ability<the third grade inhabitants reach ability.
