三峡库岸带生态屏障建设技术体系初步研究——以云阳县盘龙镇示范区为例

Preliminary Study on Technical System of Constructing Ecological Barriers in Lakeside Zone of Three-Gorge Reservoir——Taking the Demonstration Area in Panlong Town,Yunyang County as an Example

针对三峡库区水土流失、环境污染及水体自净能力下降等问题,建设符合区域发展模式的库岸带生态屏障是库区及下游地区生态安全与社会经济可持续发展的基本保障。结合实地调研,以云阳县盘龙镇示范区为例,探讨了库岸带生态屏障建设的功能分区、建设目标与建设原则,初步提出了包括9类20余种建设模式的技术体系,并就建设效益进行了分析评价,旨在提出可供三峡库区生态屏障建设参考的理论和方法。

In regard to the problems of soil and water loss,environment pollution and the deteriorating self-purification ability of the water body in Three Gorge areas,constructing ecological barriers in the lakeside zone in accordance with regional development mode will provide ecological security and sustain socioeconomic development of the reservoir and the downstream areas.Taken the demonstration area in Panlong town,Yunyang County as an example,the paper discussed functional zoning,and construction target and principles for ecological barrier construction in the lakeside zone,based on field survey on natural conditions and socioeconomic situations.The preliminary technical system,including over twenty constructional modes of nine categories,was proposed.The benefits were analyzed and evaluated in order to provide referential concepts and measures for ecological barrier construction in the surrounding regions of the reservoir.
