山东省茌平县地处鲁西,是全省沿黄渔业开发重点县,生态渔业生产基地县。“八五”以来,开发低洼盐碱地,以渔改碱,上粮下鱼为主,鸡——猪——鱼——粮——果——菜综合种养,取得显著的效益。2001年以来,县水产局在实践中又探索出生态渔业开发的新类型——挖池抬田,池中养鱼,台田面上搞硬池植藕（除去路坝占地,鱼池、藕池面积比例为5:3）,每开发1口鱼塘台面上带建2个硬化藕池,即“一拖二”开发模式。一拖二开发模式产品均为绿色水产品,无公害,而且大大改变了环境,池中鱼,岸上荷,是休闲、垂钓、娱乐首选,是渔业发展的一大方向,具有显著的经济效益、社会效益和生态效益。1 池塘规划及建设l.1选择成方连片的涝洼盐碱地或废旧窑坑,一般 Chiping County, Shandong Province is located in Luxi, is the province’s key counties along the Yellow River Fisheries, eco-fisheries production base counties. Since the “Eighth Five-year Plan” period, the development of low-salinity saline-alkali land has achieved significant benefits by comprehensively planting and breeding of fish, alkali, fish and fish, and chicken-pig-fish-food-fruit-vegetables. Since 2001, the County Bureau of Fisheries has also explored new types of eco-fishery development in practice - digging the ponds and raising fish in the ponds, and cultivating the hard ponds with lotus roots (excluding road and dam land, fish ponds and lotus ponds Area ratio of 5: 3), each developed a fishpond table with built two hardened lotus root pool, that is, “one to two” development model. One to two development model products are green aquatic products, pollution-free, but also greatly changed the environment, the pool of fish, shore Dutch, leisure, fishing, entertainment preferred, is a major direction of fisheries development, with significant economic benefits, Social and ecological benefits. 1 pond planning and construction l.1 choose into a contiguous waterlogging saline or waste pit, generally
