基于空间句法和网络分析的武汉市城郊休闲农业点空间可达性研究

Spatial accessibility of leisure agriculture in suburbs of Wuhan based on spatial syntax and network analysis

休闲农业是乡村旅游发展的重要载体,其可达性水平直接影响着乡村旅游的可持续发展.基于此,论文以武汉市城郊368个休闲农业点作为研究对象,在空间句法方法的基础上,借助网络分析方法,构建空间句法模型和空间关联性网络模型,从全局通达性、局部关联性两个方面对武汉市城郊休闲农业点的空间可达性进行研究,以揭示武汉市城郊休闲农业点的布局特征与空间关联性.结果发现:1)武汉市城郊休闲农业点整体密度核心分布较为分散,空间呈现群聚式非均匀分布在武汉市绕城高速周边,形成了绕城高速休闲农业点分布带;2)从路网全局通达性来看,武汉市城郊休闲农业点多分布在2级可达性道路300 m缓冲区范围内,且此道路等级缓冲区范围内的农庄经济型休闲农业点可进入性较好,对外通达性一般;3)从路网局部关联性来看,区域间休闲农业点内部联系“西密东疏”,东西湖区与黄陂区、蔡甸区休闲农业点联系较为密切;区域内休闲农业点内部关联性差异明显,高速公路、国道沿线区域的休闲农业点关联性普遍较强.

Leisure agriculture is an essential carrier for the development of rural tourism,and its accessibility level directly affects the development of rural tourism.Based on this,the paper takes 368 leisure agricultural points in the 11 suburbs of Wuhan as the research object.Based on the spatial syntax method,and with the help of web analytics,a spatial syntax model and a spatial association network model are constructed.From the aspects of global accessibility and local relevance,the spatial accessibility of recreational agriculture points in the suburbs of Wuhan is analyzed in order to reveal the layout preference and spatial correlation of leisure agriculture points in the suburbs of Wuhan.Result are found as follows.1)The core distribution of the overall density of leisure agriculture in the suburbs of Wuhan is relatively scattered.Spatial distribution presents clustered non-uniform distribution around Wuhan City Ring Expressway,forming the city high-speed leisure agriculture point distribution belt.2)From the perspective of the overall accessibility of the road network,the leisure agriculture points in the suburbs of Wuhan are mostly distributed in the 300 m buffer zone of the 2nd access road.Moreover,the farm economy leisure agriculture point within the buffer zone of this road grade has better accessibility while general external accessibility.3)From the perspective of local relevance of road network,inter-regional leisure agriculture point has the internal correlation pattern of“Xi Mi Dong Shu”.The Dongxihu District is closely related to the leisure agriculture sites in Huangpi District and Caidian District.The internal correlation of leisure agriculture points in the region is obviously different.The correlation of leisure agriculture points along highways and national highways is generally strong.
