河北平原农业灌溉水质监测评价

Water quality monitoring and evaluation of irrigation water in Hebei Plain

为及时掌握灌溉农业水环境的状况及变化趋势,参照农田灌溉水质评价标准,分流域选取11个监测项目,对农业灌溉水质进行了连续2年的监测,采用污染指数法对监测结果进行评价。结果表明,除个别灌溉水质存在单项超标外,地表灌溉水、地下灌溉水水质的综合污染指数均小于1。总体而言,地表灌溉水、地下灌溉水水质完全符合农业灌溉水水质要求,灌溉用水是安全、可靠的。

In order to grasp the status and trend of the agricultural water environment in a timely manner, according to the Standard for the Quality of Irrigation Water, the quality of irrigation water in a sub-watershed was monitored for 11 items in two years. The pollution index method was used to evaluate the monitoring data. The results show that the comprehensive pollution index of the surface and groundwater irrigation water is less than 1, except for individual items over the standard for single index. In summary, the quality of irrigation water meets the requirements for irrigation water. The irrigation water is safe and reliable.
