摘　　要：以川中丘陵地区大英县隆盛镇黄腊溪小流域为研究对象,结合实测和调查数据,进行了水环境容量和面源污染物入河量的研究。结果表明:黄腊溪8月～次年1月有3个月水质超标,TN总共需要削减19.36 t/a的入河量,而从月份上看8月份水质最差,则需要削减659.08 t/a、1.54 t/a、0.60 t/a的CODcr、TN和NH3-N量才能满足地表水III类水质标准,最后针对污染特征提出了该流域水环境的防治建议,为改善农村水环境具有重要意义。Huang Laxi small watershed,which locates at Longsheng town in central sichuan hilly region,was considered as the research object in this paper.With the practical measured and survey data,the water environmental capacity and the quantity of non-point pollutant were discussed.The results indicated that from August to next January,there were three months,particularly in August,the water quality condition was exceed standard in Huang Laxi,and the amount of TN should be reduced 19.36 t/a.Requires special attention,the CODcr,TN and NH3-N in August need to be decreased by 659.08 t/a,1.54t/a、0.60t/a respectively to meet the III degree standards of the water quality.Corresponding water environment prevention countermeasure and suggestion to the pollution sources were proposed,which was important to improve the water environment in rural areas.
