基于GSI的泾河新城河道环境修复设计研究
Study on Environmental Restoration Design of Jinghe New City River Based on GSI

城市河道景观价值依托于自然景观的构建。基于当前防洪压力大、河水污染严重、河道生境退化、河岸自然空间遭到破坏、河流与城市景观系统相互割裂等引发的河道生态环境问题，结合绿色雨水基础设施的设计原理，探讨了城市河流两岸的绿色雨水基础设施的原则和策略。以陕西省西咸新区泾河新城下游河道景观为例，根据泾河河道生态环境面临问题划分出河道源头控制区、生态调蓄区、生态种植区、环境修复区四个区段，并以此提出系统的方法，综合河道生态修复与景观设计的一体化进程，为其他城市河道景观设计提供参考。
The value of urban river landscape depends on the construction of natural landscape. Based on the ecological and environmental problems caused by high flood control pressure, serious river pollution, degradation of river habitat, destruction of natural space along river banks, separa-tion of river and urban landscape system, and combining with the design principle of green rainwater infrastructure, the principles and strategies of green rainwater infrastructure on both sides of urban rivers are discussed. Taking the downstream river landscape of Jinghe New Town in Xixian New District of Shaanxi Province as an example, four sections of river source control area, ecological regulation and storage area, ecological planting area and environmental resto-ration area were divided according to the ecological environment problems of Jinghe River. Based on this, a systematic method was proposed to integrate the integration process of river ecological restoration and landscape design, and provide references for other urban river landscape design.
