摘要: |
以太湖为研究对象,利用2010年实测的进出太湖的水量和水质资料计算了太湖水体自净能力,在分析河道入湖、降雨、调蓄量等入湖水量水质基础上,探索了基于质量平衡原理的太湖总氮、总磷自净能力计算方法.结果显示,通过考虑出入湖负荷量的方法得到太湖总磷和总氮的自净率约为48%和42%,采用基于质量平衡原理得到太湖总磷和总氮的自净率分别约为52%和49%.另外,还分析了这两种方法的优缺点,提出进一步研究太湖自净能力的工作方向. |

Abstract: |
On the basis of mass balance and the observed data of water quantity and in the flow-in and out rivers of Lake Taihu in 2010, the computation methods of the self-purification capacity of total phosphorus and total nitrogen of Lake Taihu are discussed. The results show that the self-purification ratio of total phosphorus and total nitrogen of Lake Taihu are about 48% and 42%, respectively, with the consideration of nutrients flowing in and out of Lake Taihu. While the self-purification ratio of total phosphorus and total nitrogen of Lake Taihu are about 52% and 49%, respectively, on the basis of mass balance. The merit and demerit of the two methods are figured out and prospected for further research is illustrated. |
