河北省河流水质时空变化特征及受人类活动的影响分析
Feature of spatial and temporal variation of water quality and in fluenceo f human activities on it in Hebei Provin ce
摘要
Abstract
The water quality identification index was used to evaluate water quality situation of seven water systems in Hebei province from 2005 to 2010.Based on the results, the paper analyzed the features of spa-tial and temporal variation of water quality in the seven water systems.Finally,it used principal component analysis and correlation analysis methods to explore the impacts of typical human activities on water quality. The result shows that the river water quality in Hebei province presented good tendency from 2005 to 2010. The water quality of Luan river, the upper stream of Beisan river and Yongding river in 2010 all reached gradeⅢand above.The water quality pollution of Ziya river, Zhangweina canals and Heilonggangyundong water systems was reduced, and the values of comprehensive water quality identification index of which dropped 16.9%, 51.3% and 16.9%respectively in 2010 compared with that in2005 , but the water pollu-tion of Daqing river is getting more serious.The spatial variations of water quality show that the main water pollution indices are CODMn , BOD5 and NH3-N.The water quality in northern areas in Hebei province is better than that in central and southern areas.Urban population density, industrial gross output, proportion of arable land and other human activity parameters present significantly positive correlations with single fac-tor water quality evaluation results of NH3N-, CODMn and BOD5.关键词
