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。
Aimed at the problems of drought and water shortage, incomplete embankment, lack of systematic shelterbelts, dumping of garbage and habitat degradation in most of the rivers in the north of China, based on the landscape hydrology theory and the comprehensive treatment of Baisha River and Zehe River in Pingdu City, Shandong Province, As an example, to discuss the normalized aqueduct landscape with “central shallow channel ” type channel section “water is blue, no water is green ”; to explore the urban rainwater from the perspective of the integration of hydrology, water conservancy and landscape , Reclaimed water supplemented river diversification water diversification method; low cost, low care and protection of wild grass flowers to create the landscape intention of rural plants; to explore with less manual intervention, less investment, financial greenway system in rural rivers, Improve the planning and design of its recreation function.
