地下水化学分类方法的思考

Groundwater chemical classification methods of thinking

地下水化学类型不仅有助于了解天然水的成因条件,而且水化学类型的递变格局也时常成为圈化地下水系统、地表水系统,以及研究两者间水利联系的重要证据。地下水化学类型分类方式很多,以舒卡列夫分类法在地下水化学分类中应用最为广泛。舒卡列夫分类法简明易懂,可以利用表格系统整理水质分析资料。但仍存在一定缺陷,容易忽略当量百分比不足25%的次要离子和无法对比主次离子关系,新的方根据阴阳离子的不同当量百分比浓度赋不同的分值的方法,可以有效地用数字表达模式表达出阴阳离子的当量百分比浓度的大小及含量区间及相同含量区间各离子的当量百分比大小的不同。解决了原有数卡列夫分类方式表达的缺陷问题。

the groundwater chemical type not only help us to understand station of pure water becomes worse condition causes,and water chemical type of alternation pattern also often become the groundwater system,surface water circle system,and the water conservancy contact between the important evidence.Groundwater chemical type classification many ways to easy card LieFu classification in groundwater chemical classification of most widely application.Easy card LieFu classification in plain,can use form system arrangement water quality analysis material.But it still has some defects,easy to overlook equivalent percentage less than 25% of secondary ions and can't contrast primary and secondary ion relations,A new method based on ion of different equivalent percentage concentration of different values of Fu method,can effectively use digital expression patterns express ions equivalent percentage concentrations of size and content interval and the same content interval of each ion equivalent percentage of different sizes.The problems of the original number of cards to Lev classification pattern of expression of defects.
