三峡水库建成后随水库年度运行将形成垂直落差 ３０ｍ的消落带．面积约 １１００ ｈｍ~2。依不同消落区域地形、出露时期等特点．选择坝拦、网拦和鱼类饲料作物栽培的方式合理利用消落带自然资源．能有效增加库区农业产出．扩大移民安置容量。在总结国内水库消落带渔业利用方式和实际效果的基础上，对三峡水库重庆库区渔业利用的可行性及适宜的技术方法进行了分析研究。
After the completion of the Three Gorges Reservoir with the annual operation of the reservoir will form a vertical drop 30m decline zone. The area is about 1100 hm ~ 2. According to different areas of the terrain, exposure and other characteristics. Choose dam bar, net bar and fodder crop cultivation ways to make reasonable use of the natural water level zone. Can effectively increase the agricultural output in the reservoir area. Expand resettlement capacity. On the basis of summarizing the fishery utilization patterns and actual effects of the hydro-fluctuation belt in the domestic reservoirs, the feasibility of using the fisheries in the reservoir area of the Three Gorges Reservoir and the suitable technical methods were analyzed.
