| 研究了柘林湾沿岸对虾养殖产生的环境氮磷负荷及其来源的数量和比例。2006年柘林湾沿岸对虾养殖产生的环境氮负荷为210.21t,其中来源于对虾的排泄氮、粪氮和残饵氮分别为157.10t、39.61t和13.50t;环境磷负荷为45.45t,其中排泄磷、粪磷和残饵磷分别为4.93t、24.87t和15.65t。对虾养殖环境氮负荷主要来源于对虾的排泄,占氮负荷的74.74%,而磷负荷主要源自粪便,占磷负荷的54.72%。柘林湾沿岸对虾养殖的环境氮磷负荷量以湾北部沿岸最大,北部、西部和东部沿岸环境氮负荷分别为144.86t、53.99t和11.36t,环境磷负荷分别为31.32t、11.68t和2.46t。 |

| This paper studied environmental nitrogen and phosphorus loading produced by the shrimp culture in the coast of Zhelin Bay，and estimated proportions of nitrogen and phosphorus loading from different sources. Zhelin Bay shrimp farming had produced environmental nitrogen loading of 210. 21 tons，excretion，feces and unconsumed feed accounting for 157. 10 tons，39.61 tons and 13.50 tons，respectively. Environmental phosphorus loading were 45.45 tons，Excretion，feces and unconsumed feed accounting for 4. 93 tons，24. 87 tons and 15.65 tons，respectively. Environmental nitrogen loading from shrimp culture mainly come from shrimp excretion and the phosphorus loading mainly came from feces. There was 144.86 tons environmental nitrogen loading in the northern coast of Zhelin Bay，53.99 tons in the western coast，and 11.36 tons in the eastern coast. Environmental phosphorus loading in Zhelin Bay were 31.32 tons in the northern coast，11.68 tons in the western coast, and 2. 46 tons in the eastern coast.
