| 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。 |

| This paper focused on the analysis of livestock and poultry waste generation (LPWG) in Henan Province.Using previously established estimation models,this paper analysed the amount of waste,the rate of their application to land,and the loading capacity of cropland in order to study the characteristics of provincial animal waste generation.Based on the farming data from Henan Statistical Yearbook,Henan Survey Yearbook,and Henan Rural Statistical Yearbook,the amount of manure,urine,total phosphorus (TP),total nitrogen (TN),chemical oxygen demand (COD),Cu,and Zn from LPWG was calculated.In addition,the application rate and loading capacity of nitrogen and phosphorus per unit field area were calculated.The results shew that the characteristics of the amount of LPWG in Henan Province varied their own laws in different stages during 2000-2014.This paper divided this period into two stages:stageⅠ(2000-2005) and stage Ⅱ(2006-2014),consistent with the studies of Fu Qiang (2012) and Yang Fei (2013) on national scales.Total nitrogen and total phosphorus increased relatively quickly as compared to the other pollutants,and they increased steadily in stage Ⅱ.The level of TP,TN,and Zn increased faster than that of the other pollutants throughout the period,and Cu increased faster than the other pollutants in stage Ⅱ.In 2000-2014,the level of TN,TP,Cu,and Zn increased by approximately 60%,and the loading capacity of manure,urine,COD,TN,and TP increased by approximately 40%.Meanwhile,the average annual growth of TN and TP was approximately 4% and 3%,respectively.These results suggested that several considerations can facilitate the formulation of reasonable and sustainable strategies of Henan Province.Firstly,the stage of fast increment (stage Ⅰ) of LPWG in Henan Province was over,and the current stage of increment (stage Ⅱ),which was relatively stable,would continue for a long time.The formulation of regulations and governance policies should adapt to the current stage and last for a long time.Secondly,the animal waste management in Henan Province should focus on TN,TP,Cu,and Zn,because these pollutants increased at a higher rate.Thirdly,the loading capacity of nitrogen and phosphorus per unit field area was no more than 0.33 and 0.25,respectively from 2000-2014.Accordingly,only one-third of the cropland is needed to meet the disposal of animal wastes from livestock and poultry farming in Henan Province. |
