Spatial Pattern And Regionalization Based On Accessibility Of The Forest Parks In Urban Agglomeration In Middle Changjiang River

Based on the spatial analysis technology of geographic information system and the method of metrological geography model, the spatial structure of the forest parks is analyzed, and the regionalization of the forest parks is analyzed. Based on the geographical location and spatial accessibility of the forest park. The author puts forward some suggestions for the development and construction of the forest parks in urban agglomeration in middle Changjiang River. The main research results are as follows:(1) From the spatial distribution characteristics, all the forest parks and provincial forest parks in the middle reaches of the Yangtze River are clustered and the state-level forest parks are randomly distributed. From the spatial distribution equilibrium, the spatial distribution of forest parks,national and provincial forest parks in the sub-urban agglomeration is mostly uneven and concentrated. From the spatial density of the spatial distribution, all the forest parks and provincial forest parks spatial distribution structure are expressed as "East dense West sparse." The spatial distribution of the national forest parks is more dispersed, and there is only one obvious high density area.(2) The average accessibility time of the forest group in the middle reaches of the Yangtze River is 38.84 min, and the overall spatial accessibility is good. The worst reachability is 166.00 min, and the accessibility is different. The average accessibility time of the national forest park is 56.75 min and the worst accessibility is 202.11 min.The average accessibility of the county-level cities in the region is 35.83 min, and the worst accessibility is 145.57 min. The average accessibility time of the prefecture level and above is 66.96 min and the worst accessibility is 242.18 min.(3) Based on the accessibility, the service scope of each forest park is calculated.According to the proximity and convenience, forest parks can cooperate. The service scopes are merged by changing the time between forest parks, and we divided the area into 162 minor regions. According to the national forest parks as high-grade forest parks, and we divided the area into 55 sub-regions. According to the prefecture-level city and county-level urban areas of service merged process, we divided the area into area: to increase the quantities of forest parks and improve the quality of scenic spots; to optimize the spatial structure of forest parks and design tourist routes; to improve the transportation network and enhance tourism and convenient transportation; relying on tourism regionalization of the forest parks, to achieve tourism resources sharing.
