摘要
吉林省西部地区是我国重要的农业区,地下水作为主要供水水源,其水质好坏对人们生产、生活影响较大,因此对该区地下水水质的分析工作十分必要。本次研究将对应分析方法运用到整个吉林省西部地下水水质分析中,选取42个水样点和17个水质指标作为评价因子,确定了水质分区及各区主要水质成分,并利用GIS软件绘制样品点分区图,结合样品点分布规律分析各区水质成分的形成原因。结果显示:水质指标被提取出两个公因子,分别反映地下水的矿化度和硬度。研究区被划分为三个区,各区的主要水质成分分别为HCO3-、SO24-和氮素(NO3-N、NO2-N),其成因受到自然因素和人为因素的双重影响。研究结果使我们在对吉林西部地下水污染防治制定保护措施时更加具有针对性。
Western Jilin Province is the important agricultural area in China. As the main source of water supply, groundwater water quality has great impact on the production and life of people. Therefore, it is essential to analyze local groundwater quality. In this paper, the correspondence analysis method is adopted to evaluate the groundwater quality of the entire western Jilin Province, 42 water samples and 17 water quality indicators are selected as evaluation factors to determine the main components in each water quality zone, and the formation reason of quality components in the different area is analyzed through combined with GIS. Two common factors are picked up to reflect the groundwater salinity and hardness, and the study area is divided into three regions. The results show that the main water quality components are HCO＋, SO4^2- and nitrogen（NO3--N, NO2 --N）, respectively, and the water quality dis- tribution characteristics is due to the double impact of natural and anthropogenic factors. The study results will make the determination of protection measures for groundwater quality more purposeful in Western Jilin province.
