| 摘 要： | 计算江苏省各地区1997～2004年畜禽粪便量及其农田负荷量,分析其时空分布特征与变化趋势。结果显示,全省畜禽粪便农田负荷量总体逐年升高,畜禽粪便农田负荷量较高地区主要集中在沿江和沿海地区,同时全省轻污染区域在逐渐缩小,而重污染区域却不断扩大,并且存在向西和东部沿海方向扩散趋势。表明,江苏省畜禽粪便污染日益严重;家禽和猪的养殖是影响江苏省畜禽粪便污染的主要因素;近海区与沿江地区畜禽粪便农田负荷量过高,对环境构成严重潜在威胁。 |
| 关 键 词： | 江苏省 畜禽粪便 农田负荷量 时空变化 |

| Abstract: | In the last eight years,the production of livestock in Jiangsu Province has been increased gradually.Based on the investigation data of 1997-2004,and according to the discharge rate of various livestock,this paper calculated the fecal pollution of livestock and its pollution load from 1997 to 2004.The result showed that the fecal amount of livestock was increased significantly,and the fecal pollution load had been increased from 12.5 t/ha in 1997 to 14.9 t/ ha in 2004.Meanwhile,the higher fecal pollution load was mainly distributed along the coast and the Changjiang(Yangtse) River,which has already been exceeded the critical value.The results indicated that the fecal pollution of livestock in Jiangsu Province became a serious problem.Therefore,it is urgently needed to strengthen prevention and control of the feces pollution from livestock. |
| Keywords: | feces of livestock pollution load spatial and temporal variation Jiangsu Province |
