摘要
全球气候变化和土地利用方式的改变对河流的动态自然过程带来不利影响。而目前人们对河流的修复重治理效果而轻自然过程,特别是风景园林与相关学科的交叉与融合研究较少,缺乏聚焦中、微尺度基于河流动态自然过程的生境恢复方法指导。基于此,从雨洪淹没、潮汐消落的河流动态自然过程规律着眼,提出对应的生境修复策略:1)恢复水陆边界的自然属性,重建泛洪区和河岸的联系;2)梯度式快速恢复近自然河岸带生境植被;3)连通感潮河涌湿地和营建关键生物生境,实现多种共生生物栖息地的再生。该方法有助于恢复河流长期、稳定的自由流动,生境在河流动态潮汐作用下异质性不断提高,从而提高河流湿地的生物多样性,还能为城市中心的居民提供亲近自然的休闲空间,以期在河流生境修复实践方面为风景园林和多学科融合提供新思路。
Global climate change and land use change adversely affect the dynamic natural processes of rivers.At the same time,the restoration of rivers focuses more on the effect of governance than on the natural process.In particular,there are few studies on the intersection and integration of landscape architecture and related disciplines,and there is a lack of guidance on habitat restoration methods focusing on medium and micro-scale dynamic natural processes of rivers.Based on this,the corresponding habitat restoration strategies are put forward from the perspective of the dynamic natural processes of flood inundation and tide ebbing:1)to restore the natural attributes of water and land boundaries and reconstruct the relationship between flood plain and river bank;2)gradient rapid restoration of near-natural riparian habitat vegetation;and 3)connecting tidal creek wetlands and constructing key biological habitats to realize the regeneration of various symbiotic habitats.The method is helpful to restore the long-term and stable free flow of rivers,and the heterogeneity of habitats is increasing under the action of dynamic tides of rivers,thus improving the biodiversity of river wetlands.It can also provide a close-to-nature leisure space for residents in urban centers,so as to provide new ideas for landscape architecture and multidisciplinary integration in river habitat restoration practices.
