城市湿地景观格局演变及湿地恢复重建研究

城市湿地景观格局演变的驱动力及生态效应研究具有重要的意义,目前研究主要集中在城市湿地景观格局及其组分的动态变化,在驱动力和恢复重建等方面的研究则是案例较多、归纳总结和机制研究相对薄弱。本文分析了形成当前研究现状的原因并提出了今后研究的方向,包括发展能够反映生态过程的景观格局指数、归纳城市湿地景观演变的驱动机制、总结湿地恢复与重建的目的与目标、建立完善的湿地恢复成效评估标准、加强城市湿地景观规划设计研究及城市湿地景观结构设计机理研究。

Patterns of Changes of Urban Wetland Landscapes and Their Rehabilitation

Studies on the driving forces for urban wetland landscape changes and their ecological impacts have significant implications. Majority of current studies are focused on dynamic changes of urban wetland landscape patterns and its components, more of which are case studies while few are on summarizing the underlying mechanisms. This paper tries to analyze the reasons for such situation and following proposals were made for future studies: developing indicators for landscape change patterns to reflect ecological processes, analyzing the mechanisms that drive the changes of urban wetland landscape patterns, summarizing the goals and objectives of wetland restoration and rehabilitation, developing criteria for assessing the effectiveness of urban wetland restoration, strengthening studies on planning, structural design of urban wetland landscapes.
