| 摘 要： | 从闽江流域畜禽养殖业现状分析入手,根据作物所需畜禽粪尿肥的最大量,估算流域各县市的畜禽污染物产生量和农田畜禽粪便负荷量,对各县市畜禽养殖粪便污染进行潜在的环境风险评价.结果表明:闽江流域大多数集约化养殖场集中分布于中上游,并有向下游扩散的趋势;流域农田畜禽粪便负荷量平均达22.95 t·hm-2·a-1;整个流域的畜禽污染已对环境产生风险,尤其是富屯溪、沙溪流域更为突出.

| Abstract: | For the purpose of environment protection,the maximum admissible pollution load of livestock manure in the Minjiang River Valley was calculated based on the principles of soil-plant nutrition and the theory of scientific fertilization.And potential environmental risk of livestock manure in every city and county in the valley was assessed.Results indicate that pollution caused by the livestock threatens environmental quality of the valley to a varying extent.In the Futun River and the Sha River,the threat is especially prominent. |
