为研究大流域较高分辨率下的潜水水质分布对气候变化的响应关系,以典型半干旱区吉林省西部平原区地下水为例,基于1980~2013年共计34年的降水和潜水水质监测数据,运用单因子和综合水质评价法对研究区潜水进行水质等级评价,并与年降水量做相关性分析,以分析潜水水质与年降水量之间的变化规律。结果表明,潜水水质与年降水量之间存在明显正相关,总体而言,降水量多的年份,潜水水质较好。该响应规律是制定地下水资源可持续利用和保护措施方案的关键,可预测极端气候场景下地下水水质的变化规律。
In order to study the relationship between the distribution of the submerged water quality and climate change at high resolution in large basins, taking the groundwater in the western plain of Jilin Province as a typical semi-arid area as an example, based on 34 years of precipitation and submerged water quality monitoring data from 1980 to 2013, The single factor and integrated water quality assessment method was used to evaluate the water quality of the submersibles in the study area and the correlation analysis was made with the annual precipitation to analyze the variation rule between the submersible water quality and the annual precipitation. The results show that there is a clear positive correlation between the submersible water quality and the annual precipitation. Generally, the submersion water quality is better in the years with more precipitation. The response law is the key to formulating the plan of sustainable utilization and protection of groundwater resources and predicting the variation of groundwater quality in extreme climate scenarios.
