| 摘 要： | 根据洞庭湖区畜禽养殖现状,采用排泄系数估算法测算了洞庭湖区畜禽粪便产生量,并对不同农地畜禽粪便承载量和畜禽粪便污染风险进行了评估.结果表明:2006年,洞庭湖区年产畜禽粪1 616.93万t,尿液1 248.30万t,BOD5 72.41万t,COD 79.33万t,NH3-N 7.48万t,农地畜禽粪便承载量平均为19.25 t·hm-2,风险预警值平均为0.47,仍未造成环境污染,畜禽养殖业还有较大发展空间.但个别地区的畜禽粪便已对农地造成污染,必须引起注意. |

| Abstract: | Based on the status of animal husbandry in Dongting Lake area, the quantity of livestock manure was estimated using the excretive coefficient method and the loading capacity and risk conditions evaluated. The results show that the output of livestock manure, urine, BOD5, COD and NH3-N in Dongting Lake area in 2006 are 1 616.93×104 t, 1 248.30×104 t, 72.41×104 t, 79.33×104 t and 7.48×104 t respectively. The average loading capacity of livestock manure reaches 19.25 t·hm-2. Forewarning average risk level of livestock manure loading is 0.47. On the average, there is no environmental pollution, and there is still room to develop animal production in Dongting Lake area. However, some cultivated lands already show livestock manure pollution, a trend that can not be ignored. |
