摘要
在系统收集大庆市近几年地表水相关资料及环境监测的数据基础上,选取有代表性的5项监测指标、9个地表水体监测断面,进行因子分析,得出地表水体主要污染为含油类有机污染和植物营养污染为大庆市地表水体的2类污染特征;在此基础上对典型水体依据因子得分进行污染程度对比并进一步采用聚类分析对地表水体进行污染类型划分;根据分析结果,结合大庆市地表水环境的污染特征和成因,提出了针对性的相应的水体污染控制措施。
Based on the collection of surface water-related information and environmental monitoring data of Daqing systematically in recent years,five representative monitoring indexes and nine surface water monitoring sections are chosen by use of factor analysis,The results reveal that the main surface water pollution of Daqing City is organic pollution which contain oil and plant nutrient pollution.On this basis,the paper compares the pollution degree to typical water according to the factor score and further uses cluster analysis to divide the surface water by the pollution types.Based on the analysis of the results,the paper proposes targeted water pollution control measures combining with the characteristics and causes of environmental pollution of Daqing surface water.
