河南省地表水水质变化趋势现状探究

Study on the Current Situation of Surface Water Quality Changing Trends in Henan Province

在河南省水资源调查评价过程中,全省纳入分析的108个水质断面中,绝大部分水质变化趋势均为无明显升降趋势或下降趋势,但仍有26个断面水质出现变差趋势,其中有19个分布在淮河区。主要原因是水资源分布与区域社会经济发展不协调和基础设施水平与社会经济发展需求不匹配,应因地制宜实施不同的改善措施。

In the process of water resource investigation and evaluation,among the 108 water quality sections included in the analysis in Henan Province,the vast majority of water quality changes showed no significant upward or downward trend,but there were still 26 sections with a trend of water quality deterioration,of which 19 were distributed in the Huaihe River basin.The main reason is that the distribution of water resources is not coordinated with regional socio-economic development,and the level of infrastructure does not match the needs of socio-economic development.Therefore,different improvement measures should be implemented according to the specific local conditions.
