基于景观水文理论的郊野型河道景观规划设计——以山东平度市白沙河、泽河为例

Study on Landscape Planning and Design of Suburb River Based on Landscape Hydrology——A Case of the Baishahe and Zehe of Pingdu in Shandong

针对我国北方郊野型河流多数存在河道干旱缺水,堤线不完整,缺乏系统的防护林带,垃圾倾倒及生境退化等诸多问题,基于景观水文理论,以山东平度市白沙河、泽河综合治理为例,探讨以"中心浅河道"型河道断面营造"有水则蓝,无水则绿"的常态化有水河道景观;以水文、水利与景观相融合的视角探讨城市雨水、再生水补充河道景观用水的多元化补水方法;以低成本、低管护的野生草花营造郊野型植物景观意向;同时探讨以较少人工干预、较少投资,融绿道体系于郊野型河道,完善其游憩功能的规划设计方法。

Most of China＇s northern suburb-rivers face the problem of drought and water shortage,incomplete dike line,lack of systematic shelterbelts,dump and habitat degradation. Based on the theory of landscape hydrology,this paper takes Baishahe and Zehe water system renovation of Pingdu as an example,exploring the ″center shallow river″ section to create a normalization of landscape water river; from the perspective of integration of hydrology,water conservancy and landscape to discuss urban rainwater and recycled water to add waterway; creating a suburb type of plant landscape intention with low cost,low management wild flower. At the same time,we also discussed the minimal manual intervention and minimal financial investment of greenway system in suburb river to improve the recreational function.
