摘　　要：洞庭湖拥有大片低洼湖田,由于地势低洼,受洪涝灾害影响大,因此目前主要以种植一季中稻为主,其他时间处于闲置状态,极大影响低洼湖田的高效利用。为此,洞庭湖区低洼湖田虾稻轮作复合农业模式的集成与创新得到了持续推动和完善,针对湖南省岳阳市君山区良心堡镇护城村8 hm2低洼湖田虾稻轮作进行试验,结果表明:虾稻轮作模式使低洼湖田没有闲置期,且避开了洞庭湖区主要的气象灾害且改良土壤,全年产值53 841元/hm2左右,较原来仅种植一季中稻增加产值31 827元/hm2。低洼湖田虾稻轮作复合农业模式是一种高效的经济生态型模式。There are a lot of shoaly land around Dongting lake area, the shoaly land are affected by the floods, so the mainly planting pattern in the shoaly land is middle-season rice.The pattern of lobster rice rotation with composite integration and innovation of agricultural patterns was continued to be promoted and perfected.In shoaly land of Dongting Lake, there is 8 hectare shoaly land in Hucheng Village, Liangxingbao Town in Yueyang City ,which was elected as the research object to carry out technical expeirment of rice and lobster rotation.The preliminary results showed that the lobster rice rotation pattern avoided the main meteorological disasters of Dongting lake and improved soil, the total output value was 5384 yuan per hectare ,compared with middle-season rice ,the lobster rice rotation pattern increase the output value about 31827 yuan per hectare.The lobster rice rotation pattern in the shoaly land is a kind of efficient ecological economy.
