【摘要】：为研究省域畜养产污规律,在构建畜养产污核算、农田消纳、承载负荷模型的基础上,以河南省为例分析了河南省主要畜种的产污量和单位面积的N、P消纳量及承载负荷。结果表明,河南省2014年畜养产污粪便、尿液、COD、TN、TP、Cu、Zn分别为6 307.53万、6 165.88万、1 315.67万、80.67万、12.60万、0.16万、0.48万t;2000—2014年河南省畜养产污存在着阶段性规律,TN与TP的增长相对较快,但目前已趋于稳定;2014年河南省单位面积农田N、P的承载负荷分别为0.33和0.25,引导三分之一的作物种植面积用于畜养产污的还田利用就能够满足当前河南省畜养产污的消纳需求。研究方法对接污染源普查核算工作,综合考虑各畜种的养殖周期、养殖阶段和在省域的结构性变化,能够探索出不同畜养污染物在研究期内的变化差异性。
[Abstract]:In order to study the regulation of livestock production and pollution in the province, based on the construction of the model of the calculation of livestock production, the absorption of farmland and the load, taking Henan Province as an example, this paper analyzes the amount of pollution production, the amount of NBP absorption per unit area and the carrying load of the main livestock species in Henan Province. The results showed that the COD,TN,TP,Cu,Zn of feces, urine and urine were 63.0753 million, 61.6588 million, 13.1567 million, 806700, 126000, 1600, 4800 t respectively. From 2000 to 2014, there were periodic laws of livestock production in Henan Province. The growth of TN and TP was relatively fast, but it had been stable. In 2014, the carrying load of N N P per unit area in Henan Province was 0.33 and 0.25, respectively. 1/3 of the crop planting area could be used for the utilization of livestock production and sewage in Henan Province, which could meet the current demand for the absorption of livestock pollution in Henan Province. Research methods connected with the survey and calculation of pollution sources, considering the breeding cycle, breeding stage and structural changes in the province, we can explore the differences of the changes of different livestock pollutants in the research period.
