游憩型绿色开放空间的可达性与服务便捷性测度——以天津市内六区为例

以天津市市内六区为例,基于城市游憩型绿色开放空间斑块、道路网和街区单元人口分布等数据,利用GIS的Cost Weighted工具,重点分析了研究区内步行、自行车和公交及私家车3种交通方式下的时间可达性,及各行政区与街道的服务便捷性特征。分析结果表明,研究对象在天津市内六区的整体可达性较好,基本上步行10分钟,或自行车和公交及私家车方式下5分钟内即可到达研究区的大部分区域;各行政区及街道的可达性在3种交通方式下空间分布差异较大,在自行车和公交及私家车方式下能够更好地满足研究区内居民的日常休闲游憩需要。

Taking interior six districts of Tianjin for example and using Cost Weighted tools in GIS, this essay mainly analyzes the time accessibility and convenient service features of districts and street scale for three kinds of means of transportation on foot, bike, bus and private cars based on patches of green open space for recreation, road network, population distribution of block unit. The results show the whole accessibility of green open space for recreation in interior six districts of Tianjin is good, and most of the regions can be arrived within 10 minutes on foot, 5 minutes by bike, bus and private cars. The accessibility of space distribution difference for districts and street scale is relatively large in three kinds of traffic mode. And the means of transportation for bicycle, bus and private cars carl satisfy the daily leisure and recreation of the population in a great degree of study area.
