都市慢行系统周边绿色开放空间分配研究--以漯河市为例

The Allocation of Green Open Space Around the Slow-TrafficSystem of Luohe City

为探究漯河都市慢行系统与绿色开放空间分配的内在联系,把握漯河慢行系统空间布局特征与绿色开放空间分布现状的缺陷与不足,进而构建都市区便捷、通达、高效的慢行绿色开放空间耦合体系.基于空间句法理论,利用Depthmap X软件,对高精度无人机影像解译的漯河城市道路空间结构与绿地资源分布数据进行耦合分析.高精度影像下显示:①道路空间结构布局方面,研究区整体体现出了极高的布局成熟度,这其中以北区最高,滨河区最低.②街道尺度,绿色开放空间资源供给错位,在西、东和滨河三个区域中,开放绿地率与道路局部整合度不具有显著相关性.

To explore the intrinsic relationship between the slow-traffic system and the distribution of green open space in Luohe City,we pointed out the spatial layout characteristics of the slow-traffic system of Luohe and the defects and shortcomings of the distribution status of green open space,and then constructed the convenient,accessible and efficient slow-moving green open space coupling system in the urban areas.Based on the theory of spatial syntax,by using Depthmap X software,coupling analysis was carried out on the interpretation data of high accuracy uav image of road spatial structure and green space resource distribution in Luohe City.The results with high-precision image show as follows.①For road space structure layout,the study area wholly reflects a very high degree of layout maturity.The highest is in the north and the lowest in the riverside area.②At the street scale,there is a misalignment for green open space resource supply.In the west,east and riverside regions,the rate of open green space and the degree of local integration of roads are not significantly correlated.
