基于空间句法的福州市公园绿地布局优化研究

Optimization of park green space layout in Fuzhou based on space syntax

以福州市台江区17个公园绿地作为研究对象,基于空间句法理论,利用Dpthmap和Arcgis软件建立线段模型,从全局可达性、局部可达性、感知可达性以及全局深度与连接度的比值四个维度,对台江区公园绿地可达性进行综合评价,提出优化策略。结果表明:台江区公园绿地全局可达性,局部可达性较好,但存在公园绿地可达性个体差距较大的现象。感知可达性总体较高,但有部分公园绿地对居民吸引力不足,使其局可达性与连接度的比值低于均值。部分公园全局深度与连接度的比值较低,说明公园绿地规模与空间品质需要提升。为此,从完善公园绿地周边道路、适当增设公园绿地以及提升公园品质等方面提出相应对策,以期为城市绿地布局优化提供一定启示。

Taking 17 park green spaces in Taijiang District,Fuzhou City,as the research object,based on the spatial syntax theory,using Dpthmap and Arcgis software to establish the line segment model,from the four dimensions of global accessibility,local accessibility,perceptual accessibility,and the ratio of global depth to connectivity,the accessibility of park green spaces in Taizhou District is comprehensively evaluated,and the optimization strategy is proposed.The results show that the global accessibility and local accessibility of parks and green spaces in Taijiang District are good,but there is a phenomenon of large individual differences in the accessibility of parks and green spaces.Perceived accessibility is generally high,but there are some park green spaces that are not attractive enough to residents,making their ratio of global accessibility to connectivity lower than the mean value.The ratio of global depth to connectivity of some parks is low,indicating that the scale and spatial quality of park green spaces need to be improved.In this regard,corresponding countermeasures are proposed in terms of improving the roads around the parks,appropriately increasing the parks and improving the quality of the parks in order to provide some insights for the optimization of the layout of urban green spaces.
