基于分区、分级的城市道路空间景观设计研究--以成都市简州新城龙腾大道为例

Research on Urban Road Spatial Landscape Design based on Zoning and Grading Design--Taking Longteng Avenue,Jianzhou New Town,Chengdu as an example

龙腾大道是成都市简州新城起步阶段最重要的交通要道之一,除了满足最基本的道路交通功能以外,还需要承担提升城市环境品质、展示新城建设信心与实力等任务。为了实现景观有效提升、资源高效配置的设计目标,龙腾大道采取了分区、分级的景观设计方式。一方面将景观主题分为“起、承、转、合”四个段落,另一方面将空间节点分为功能区级、街道级、社区级三个级别。通过分区、分级合理分配设计时间和经济成本,高效打造高品质道路空间景观。

Longteng Avenue is one of the most important traffic arteries in the initial stage of Jianzhou new town in Chengdu.In addition to meeting the most basic road traffic functions,it also needs to undertake the tasks of improving urban environmental quality and demonstrating the confidence and strength of new town construction.In order to achieve the design goal of effective landscape improvement and efficient resource allocation,the designer adopts the landscape design method of zoning and grading to design Longteng Avenue.On the one hand,the landscape theme is divided into four paragraphs of“starting,undertaking,transfer and combination”.On the other hand,the spatial nodes are divided into three levels:functional area level,street level and community level.Through zoning and grading design,designers can reasonably allocate design time and economic cost to create high-quality road space landscape efficiently.
