摘要
湿地生态系统中各种生物、化学和物理过程活跃,大规模的城市化进程显著改变了这些过程,影响着城市及周边区域的湿地景观组分、功能与结构。从城市湿地定义与分类、格局演变、格局与生态-社会过程耦合模拟3个方面综述了国内外湿地景观格局结合城市背景的研究成果。通过归纳当前研究现状,指出城市湿地景观研究的薄弱环节与亟待发展的领域,构建融合关键生态特征的城市湿地景观分类体系,整合社会经济要素的城市湿地格局与过程耦合模型,以及耦合模型在城市规划与区域资源管理中的应用。
Biological, chemical and physical processes occur actively within wetland ecosystems. Large-scale urbanisation significantly changes these processes and impacts landscape composition,fi, nctions and patterns of urban and peri-urban wetland. This article reviews studies on wetland landscape with specific focus on urban environments from three perspectives: urban wetland definition and classification,landscape evolution,and simulation of spatio-temporal coupling mechanisms between wetland landscape patterns and ecological-social processes. The purpose of this article is to analyse the merits and limitations of current studies and point out some hotspots research and application: establishing an urban ecological classification system which incorporates key wetland ecological elements and dynamics,integrating social and economic elements into the coupling simulation of urban wetland landscape pattern and processes,and the application of such simulation models in urban planning and sustainable regional development.
