基于生态弹性的北京市“二道绿隔”温榆河段郊野公园设计

生态弹性通过研究人与自然系统的关系,为缓解生态危机、建设美丽中国提供了新的视角。文章以北京市"二道绿隔"温榆河段的郊野公园组团为例探讨生态弹性导向下的郊野公园体系设计策略:一是从缓解河道行洪压力、形成区域海绵系统、公园水网循环建设3方面构建弹性水系统;二是通过推进适应性生态演替与设计旱雨两宜生境构建弹性生境系统;三是构建生态游览系统。

Country Park Design of Wenyu River Section of Second Green Belt Area in Beijing Based on Ecological Resilience

Ecological resilience provides a new perspective for mitigating ecological crisis and building a beautiful China by exploring the relationship between human and natural systems.This paper takes the country parks along the Wenyu River section of second green belt area in Beijing to explore the design strategies of the country park system oriented by ecological resilience.Constructing the resilient water system can be realized from 3 aspects:relieving the flood discharge pressure over the river course,forming the regional sponge system and improving the park water network.The resilient habitat system can be built by promoting the adaptive ecological succession and designing the habitats suiting both rainy and dry seasons,with the support from the ecological touring system.
