湖滨带生态恢复与重建的理论与技术研究

湖滨带是湖泊水、陆地生态系统间重要的过渡带,其独特的环境特征,使该区域内的生态因子兼有相邻系统的部分特征而又不同于其相邻系统,成为与两者密切相关的独立的生态系统。近年来越来越多湖泊的湖滨带受人类干扰而严重退化,加强湖滨带的基础理论及工程实践研究,恢复和重建湖滨带生态系统的结构,充分发挥湖滨带生态功能成为当前湖泊治理中的重要工作。通过综述国内外在湖滨生态系统的受损或退化的诊断、生态恢复和重建目标等方面理论的研究状况,介绍湖滨带生态恢复和重建的有关技术和对湖滨带恢复和重建成功与否判别方面的进展。

Theories and Technologies on Restoration and Reconstruction for Ecological Zone of Lakeside

Aquatic-terrestrial ecotone is an important transition zone between aquatic ecosystem and terrestrial system for lake.Because of particular environmental characteristics for the ecotone,lakeside becomes a substantive system,whose eco-factors hold most characteristics of its neighbor systems'.Recently,more and more lakeside zone ecosystems have been degraded under the anthropic activities.Therefore,restoration and reconstruction of lakeside zone ecosystem to make the best exploitation of ecological function become the most imperative work in the lake pollution control currently.Based on theories of ecological restoration and reconstruction on aquatic-terrestrial ecotone,the present article reviews the diagnosis of the damaged or degraded lakeside zone ecosystem and the objective of its restoration and reconstruction besides the key techniques of engineering and the evaluation to the ecologically aquatic-terrestrial ecotone restoration.Finally,several suggestions concerning integrated management ecosystem are also put up for future studies.
