根据生态学原理和沿黄孝里洼区的生态环境,1987—1990年以渔为主鱼、藕、粮、牧、林、果、草综合开发5000亩。生产商品570万公斤,比原定年产百万公斤超标42.5%;种养9920亩,亩均获利433.4元,超指标(200元)116.7%;产值956万元,是开发前洼区产值60万的16倍.筛选了“鱼—牛—草”、“鱼—鹅—草”、“鱼一草”、“鱼一粮”能形成良性生态循环的生产方式。 According to the ecological principles and the ecological environment along the Huang-Hsiao-Li-Wa-Waqiu District, a total of 5,000 mu of land was mainly made up of fish, lotus root, grain, animal husbandry, forestry, fruit and grass from 1987 to 1990. Production of 5.7 million kilograms, more than the original annual output of 1 million kilograms exceeding the standard 42.5%; cultivate 9,920 acres, acres of profit 433.4 yuan, exceeding the target (200 yuan) 116.7%; output 9.56 million yuan, is the development of pre-depressions value 16 times of 60000. Screening of “fish - cow - grass”, “fish - goose - grass”, “fish a grass”, “fish a grain” can form a virtuous ecological cycle of production.
