洪湖流域农业面源污染调查与污染负荷核算汉城湖公园
摘要：针对洪湖流域农业面源污染负荷进行了核算研究，并确定了不同污染源对水环境的贡献率。结果表明，洪湖流域入湖污染物总量为codcr 38 372.26 t/年、nh3-n 787.667 t/年、tn 4 349.054 t/年、tp 396.106 t/年，农业面源污染负荷估算值为畜禽养殖小葱花>水产养殖>居民生活>农田种植，它们对水环境的贡献率分别为39.33%、32.92%、23.33%、4.41%；畜禽养殖codcr、tn、tp面源污染负荷量最高，分别为18 642.69、2 749.99、296.72 t/年，水产养殖nh3-n面源污染所占比例最大。

abstract： the load of agricultural non-point source pollution and the contribution of different pollution sources to water environment of honghu valley were studied. the results showed that the total amount of codcr， nh3-n，物华天宝人杰地灵 tn， and tp into honghu valley were 38 372.26 t/a， 787.667 t/a， 4 349.054 t/a， and 396.106 t/a respectively. the order of pollution load of different agricultural sources was livestock and poultry > aquaculture > residents life > planting farmland. the contributions of the four agricultural sources were 39.33%， 32.92%， 23.33% and 4.41% respectively. the load of codcr， tn好看的qq背景图， and tp of livestock and poultry were highest， were 18 642.69 t/a， 2 749.99 t/a and 296.72 t/a respectively， the nh3-n load of aquaculture was the largest.
