Research on spatial distributions and accessibility of scenic areas in the Yangtze River Delta
【Intention】The Yangtze River Delta has formed many scenic areas with its rich natural and cultural landscapes, which impacts the construction of ecological protection patterns and the development of regional green integration. The quantitative analysis of the distribution and accessibility characteristics of scenic spots in the Yangtze River Delta, the construction of a research framework on the spatial distribution and accessibility of scenic spots at the regional scale, and the overall analysis of the spatial structure of the scenic spots system in the Yangtze River Delta region will help rationalize the use of scenic resources and promote the sustainable development of the region. 【Method】The spatial distribution and accessibility of 123 scenic areas in the Yangtze River Delta were analyzed using ArcGIS platform and mathematical models considering the multi service radius and the level as well as the type of scenic areas.【Result】(1) The Yangtze River Delta scenic areas are “dense in the south and sparse in the north” and range from random to dispersed. (2) The discrepancy of accessibility distribution is significant, and the spatial polarization varies under three search radius. With the increase of the radius threshold, the accessibility level has an overall upward trend. In addition, the accessibility aggregation characteristics of counties are higher under the three radii, and the hot areas are mainly distributed in Huangshan, Xuancheng, Lishui, Hangzhou, Jinhua, Suzhou and Wuxi, while the cold areas appear in Shanghai and its surrounding areas. (3) Among the different levels, the accessibility of national scenic areas is better than that the of provincial scenic areas. The accessibility of independent scenic areas is better than the combined urban and scenic areas. (4) Accessibility is affected by different objective factors, and the degree of correlation is in the order of: distribution density of scenic areas > population distribution > road network density. 【Conclusion】The distribution and accessibility of scenic areas in the Yangtze River Delta show significant regional differences. This research provides a reference for the integration of resources, systematic management and regional tourism development in the scenic areas in the Yangtze River Delta.
