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.
