摘要
当前,国内非点源污染的相关研究中并无关于大中型河流非点源污染负荷估算的分析成果。在概述乌伦古河流域污染概况的基础上,运用输出线性模型,并结合相关统计资料进行了流域非点源污染负荷估算。结果表明,目前非点源污染是仅次于工业点源污染和城市生活源污染的第三大污染源,而且根据流域社会经济发展及产业结构调整的趋势预测,非点源污染在总污染负荷中的占比呈持续上升态势,所以,流域管理部门应在稳步推进对工业点源污染和城市生活源污染治理的同时,积极采取措施应对非点源污染,防止其进一步扩大。
At present,there is no analysis result on the estimation of non-point source pollution load of large and medium-sized rivers in the relevant domestic research on non-point source pollution.Based on an overview of pollution in the Ulungur River Basin,this paper used an output linear model to estimate the non-point source pollution load in the basin combined with relevant statistical data.The results show that non-point source pollution is currently the third largest pollution source after industrial point source pollution and urban domestic source pollution,and the proportion of non-point source pollution in the total pollution load continues to increase according to the forecast of the social and economic development of the river basin and the adjustment of industrial structure.Therefore,the river basin management department should,while steadily advancing the treatment of industrial point source pollution and urban living source pollution,actively take measures to deal with non-point source pollution and prevent its further expansion.
