青岛市历史街区街道结构与旅游要素空间分布关联研究

Study of the spatial relations of street structure and tourism elements distribution in historic district in Qingdao City

运用空间句法分析青岛市历史街区街道结构,核密度法刻画旅游要素分布特征,利用双变量相关分析法研究二者在不同尺度下的关联关系.研究发现:历史街区街道结构在不同尺度下具有一定差异,随着尺度不断扩大,整合度、街道密度高值核心区域向四周延伸,选择度由小范围高值核心区域转变为贯通各历史街区之间及内部的交通干道.不同尺度下整合度、街道密度与旅游要素分布关联程度存在差异,800 m尺度下关联性最高;历史街区与各类旅游要素分布相关性也存在差异,与餐饮类要素相关程度最高,与景点无相关性.选择度与旅游要素分布相关性较弱.

The space syntax model and the kernel density estimation were used to compute street structure indicators and analyze the spatial structure oFtourism elements.Further,the Pearson correlation coefficient was used to analyze the correlation between street structure and tourism elements distribution at different scales in Qingdao City.The results show that the street structure oFhistoric district has certain differences at different scales.With the continuous eXpansion oFthe scale,it eXtends from the core area with high integration degree and street density to the surrounding areas.Choice value has changed from a small range oFhigh-value core areas to a traffic trunk road that runs through each historical district and its interior.The street structure is highly correlated with the distribution oFtourism elements at different scales oFhistoric district,and 800m scale is the best scale for the agglomeration oFtourism elements.The correlation between choice value and the distribution oFtourism elements is weak.The street structure has the highest correlation with catering elements,but has no correlation with scenic spots.
