公园城市背景下的城市型绿道布局适宜性 评价研究

随着居民对慢行空间品质要求的逐渐提高,建设绿 色开放包容共享的城市型绿道尤为重要,但目前中国绿道还存 在网络不健全、功能价值单一等问题。公园城市背景下城市型 绿道在城市公共空间的设计理念、功能价值等方面不断升级, 结合多源大数据,构建公园城市背景下城市型绿道布局适宜性 评价指标体系与技术路线。最后以西安沣东地区为例,利用大 数据分析识别“出发地-路线-目的地/节点”,叠加得到适宜 性得分最高的道路,通过最优路径分析并修正得到城市型绿道 布局最终结果,该结果提升了游憩资源可达性,很好地起到接 驳公共交通的作用,为慢行出行提供良好的线路,可为未来建 设公园城市理念下绿色共享的城市型绿道提供一定参考。

Research on the Suitability Evaluation of Urban Greenway Layout under the Background of Park City

With the gradual improvement of residents'' requirements for the quality of slow moving space, it is particularly important to build a green, open, inclusive and shared urban greenway. However, at present, China''s greenway still has problems, such as imperfect network and single functional value. Under the background of Park City, urban greenway continues to upgrade in the design concept and functional value of urban public space, combined with multi-source big data, construct the suitability evaluation index system and technical route of urban greenway layout under the background of Park City. Finally, taking Fengdong area of Xi''an as an example, the "departure-route-destination/node" is identified by big data analysis, and the road with the highest suitability score is superimposed. The final result of urban greenway layout is obtained through optimal path analysis and correction. This result improves the accessibility of recreational resources, plays a good role in connecting public transport, and provides a good line for slow travel. It can provide some reference for the construction of green and shared urban greenways under the concept of Park City in the future.
