基于时间和空间差异的事件性植物景观规划设计——以河北省第二届园林博览会公共区为例

Design and Planning of Planting in Event Landscape based on Time and Space Difference:A Case Study on Public Area of the Second Garden Expo of Hebei Province

事件性景观已经成为提高城市影响力、推动城市环境更新的有效手段,植物是事件性景观得以演变并富有自我形象特征的重要介质。文章首先分析事件性植物景观具有临时性、永久性、展示性、科普性的特点,再以河北省第二届园林博览会公共区为例,对其植物景观规划设计进行时间和空间两方面的分析,将其在时间上分为会时与会后,空间上分为点、线、面三类进行事件性植物景观的营造,点状的植物景观包括功能性基础设施、特色主题花园以及植物专类花园;线状的植物景观包括园区边界、水陆边界、道路边界;面状的植物景观包括境域植物组团、现状植物组团。并根据时间和空间的差异提出不同时期、不同类型的植物景观规划策略,以期为后续园博会公共区的植物景观规划设计提供参考与借鉴。

The event landscape has become an effective means to improve the influence of the city and promote the renewal of the urban environment.Plants are the important medium for the evolution of the event landscape and rich in self-image characteristics.This paper first analyzes the characteristics of the event plant landscape,which is temporary,permanent,exhibiting and popular science.Then,taking the public area of The Second Garden Expo in Hebei Province as an example,it analyzes the plant landscape planning and design from two aspects of time and space.The time is divided into the meeting time and after the meeting,and the space is divided into three types:point,line and surface.Plant landscape includes functional infrastructure,characteristic theme garden and plant specific garden;linear plant landscape includes park boundary,land and water boundary,and road boundary;plane plant landscape includes landscape plant group and current plant group.According to the differences of time and space,different types of plant landscape planning strategies are put forward in order to provide reference for the plant landscape planning and design in the public area of the following garden expo.
