摘要
利用现代技术对地下水资源化学要素、水质进行时空演变分析,对于指导地下水的合理开采和利用意义重大。本文以辽宁朝阳地区为对象,在各个分区取水样检测其主要化学成分,得出水质总体呈弱碱性,而且地下水成分比较稳定。同时,发现水体中的化学离子呈现较明显的季节变化性,因此可知,降水、人工开采是影响该地区地下水化学离子变化的主要因素;利用GIS技术中的IDW插值法,对项目区的水质等级区域进行了预测和划分,最终表明10年时间地下水质量提升明显,为以后类似治理工作可提供必要参考经验。
Using modern technology to analyze the temporal and spatial evolution of chemical elements and water quality of groundwater resources is of great significance to guide the rational exploitation and utilization of groundwater.Taking Chaoyang area of Liaoning Province as the object,the main chemical components of water samples were detected in each area.The results show that the water quality is weak alkaline and the composition of groundwater is relatively stable.At the same time,it is found that the chemical ions in the water body show obvious seasonal variation,so it can be seen that precipitation and artificial exploitation are the main factors affecting the change of chemical ions in the groundwater in this area.The IDW interpolation method in GIS technology is used to predict and divide the water quality grade areas in the project area,and the final result shows that the groundwater quality has improved significantly in 10 years,which provides reference for similar treatment work in the future It can provide necessary reference experience.
