| Beiling Park is the most representative park in Shenyang that concentrates Han Manchu and Mongolian culture.It is very important to analyze the accessibility of Beiling Park and make suggestions for its future reasonable planning.It is very important to promote the history and culture of Shenyang.It not only provides a scientific basis for the construction of urban parks and green spaces in the third ring road of Shenyang.It will also have certain reference value for the planning of the road space network system within the third ring road in Shenyang.Through Arc GIS and space syntax,it analyzes the difficulty of the residents in the third ring road of Shenyang to reach Beiling Park,and evaluates the accessibility of Beiling Park.Extract the main road network within the third ring road in Shenyang from OSM,use Arc GIS network analysis to obtain the reachable area value of different entrances of Beiling Park at different time periods of walking,bicycle,and motor vehicles,and count the different ways of travel at different entrances The percentage of the reachable area of different administrative regions in different time periods to the total area of the study area,the larger the percentage value,the better the accessibility.Use the space syntax Depthmap software to analyze and calculate the global integration value,the local integration value of 1000 m,5000m,10000 m,15000m,20000 m,and the intelligibility of the buffer zone of 1000 m,5000m,10000 m,15000m,20000 m centered on four entrances The higher the global integration value,the better the global accessibility,the higher the local integration value,the better the local accessibility,the higher the intelligibility value,the better the perceived accessibility.After analysis,the following conclusions are reached:1.In the Arc GIS network analysis method,as the time period increases,the percentage value of the reachable area of each park entrance gradually increases;in the spatial syntax analysis,the local integration value of each park entrance is 1000m>5000m>10000m> 15000m>20000m.Regardless of the travel mode,as the travel distance increases,the accessibility gradually improves.Improving the road network and improving the means of transportation are the main ways to improve accessibility.2.In the Arc GIS network analysis method,the total reachable area of the east entrance is the largest under different travel modes;the local integration values of 5000 m,15000m,20000 m and the 1000 m buffer intelligibility value of the western entrance in the spatial syntax analysis method are larger than other entrances,and the key construction is To the east and west entrances,additional facilities such as bus stops and parking lots are added to improve accessibility.In both analysis methods,it can be concluded that for a large park,the choice and setting of the entrance location greatly affects the accessibility of the park,especially the walkability.3.Through spatial syntax analysis,it can be seen that the accessibility level of Beiling Park is still very high within a 1000 m walking range,but Arc GIS network analysis shows that more than 90% of the residents in the study area cannot reach the north within an hour.In the Mausoleum Park,the walking range is greatly restricted,but with the increase of time,that is,the increase in travel distance,the reachable range of the east,west,front,and north entrances gradually increase.It can be used in the process of road construction.Consider adding some recreational trails to Beiling Park near Beiling Park to improve the walkability of Beiling Park.4.As the service radius increases,the warm color range of the local integration map spreads from the center to the surroundings,and mainly spreads to the southwest,indicating that the center and the southwest are more accessible.In the future,there will be additional parks in the third ring road of Shenyang.In the case of green space,in addition to considering the center of the city's first ring road,you can also consider building a park green space in the southwest.Residents within the Third Ring Road of Shenyang City go to Beiling Park through the central area and the southwest road network,making it easier to reach Beiling Park. |
