| 摘 要： | 在实地调研和遥感解译的基础上，采用清单分析方法和等标污染负荷法，研究了大莲湖区域水产养殖和水生经济作物茭白种植特征性农业主要生产模式下面源污染化学需氧量（COD）、总氮（TN）、总磷（TP）排放量及其排放负荷。结果表明：大莲湖区域农业面源污染COD、TN、TP年排放总量分别为78．3、2．6、0．9t，其中鱼类养殖年排放量分别为53418．55、832．50、554．02kg，为水产养殖业主要污染源；茭白单作年排放量分别为6880．50、756．20、100．13kg，为种植业主要污染源；区域农业面源污染等标年排放总量达到45524m3，主要污染物为TP，等标污染负荷比达到77．07％；主要污染源为鱼类养殖，等标污染负荷比达到60．16％。

| Abstract: | Based on the field investigation and remote-sensing data,the discharge and load of COD,TN and TP of nonpoint source pollution from the aquaculture and aquatic economic crop production in the Dalian Lake area were studied by the inventory analysis method and equivalent standard pollution load method.The results indicated that the annual discharge amounts of COD,TN and TP from agriculture in this area were respectively 78.3,2.6 and 0.9 t,of which 53 418.55 kg of COD,832.50 kg of TN and 554.02 kg of TP were fr... |
