On the Eco-friendly Utilization of Littoral Wetland of Three Gorges Reservoir

The littoral wetland,which was formed after impounded by Three Gorges reservoir,is not only the crucible to us,but also the ecological opportunity.On the one hand,organic material of the littoral wetlands accumulated during the growing season decompose anaerobic underwater and become the second pollutant sources in winter inundating season of Three Gorges reservoir.On the other hand,we should know the carbon and nutrients accumulated by the vegetation of large-scale hydro-fluctuation belt is a very valuable resource,if properly used,can turn harm into advantage.In view of the current status and existing problems of the littoral wetland in Three Gorges reservoir,we should focus on utilizing resources of the littoral wetland eco-friendly.Based on the needs for the littoral wetland transforming into the multifunctional ecological economic benefit such as increasing carbon sources,biological production,and environmental purification,we must develop the integrated model of utilizing the wetland resources of the littoral zone eco-friendly,include dike-pond engineering,wetland woods engineering,floating-bed engineering,multifunctional wetland agriculture,wetland conservation and restoration,and so on.
