【目的】长三角地区以其丰富的自然与人文景观形成了众多的风景名胜区,在长三角生态保护格局构建和区域绿色一体化发展中担任重要角色。定量分析长三角风景名胜区的分布与可达性特征,构建区域尺度下的风景区空间分布和可达性的研究框架,整体分析长三角区域风景区体系的空间结构,有助于合理利用风景名胜资源,促进区域可持续发展。【方法】 以长三角地区123处风景名胜区为对象,在综合考虑多种服务半径及风景区级别与类型属性的前提下,利用ArcGIS平台和数学模型分析其空间分布与可达性。【结果】 ①长三角风景名胜区整体上具有“南密北疏、一片多点式”、随机趋向于离散的分布特征。②长三角风景名胜区可达性分布差异化显著,3种搜索半径下呈现不同程度的空间极化现象,可达性等级随半径阈值增加整体呈提升趋势;3种搜索半径下县域可达性聚集程度均较高,热点区主要分布在黄山、宣城、丽水、杭州、金华、苏州、无锡等地,冷点区出现在上海及其周边地区。③不同等级中,国家级风景名胜区可达性优于省级风景名胜区;不同类型中,独立型风景名胜区可达性优于城景结合型风景名胜区。④可达性受不同客观因素影响,相关程度从强到弱依次为:风景名胜区分布密度>人口分布>路网密度。【结论】 长三角地区风景名胜区分布与可达性呈现出明显的地域差异。本研究可为长三角风景名胜区资源整合梳理、系统化管理以及区域旅游开发提供参考。

【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.
