　　为了查明绥化市的地下水环境状况，运用描述性统计、地统计学理论、相关分析、Piper三线图法等对绥化市的地下水水化学特征进行全面分析。在此基础上采用了基于综合赋权的五元联系数法对研究区水质现状进行评价，并且利用秩相关系数法进行水质变化趋势分析。结果表明，研究区地下水略偏酸性，部分水样的水质指标存在超标现象。地下水中Ca 2＋为优势阳离子，HCO 3－为优势阴离子。研究区的铁、锰、氟超标是受原生污染影响，地下水中的Cl－与SO 2－4，Na＋与Mg 2＋存在同一来源。将基于综合赋权的五元联系数法的评价结果与模糊综合评判法相比较，结果表明其评价结果是合理可靠的，符合客观实际。通过秩相关系数法表明研究区地下水水质状况在一定程度上有所改善。

In order to investigate the environmental conditions of groundwater in Suihua City , the hydro-chemical characteristics of groundwater were analyzed using descriptive statistics , the geo-statistical method, the correlation analysis, and the piper diagram.Based on this, the groundwater quality was assessed with the five-element connection number method based on comprehensive weight , and its change trend was analyzed with the rank correlation coefficient method.The results show that the groundwater was slightly acidic and the water quality indices of some samples exceeded standard values .The major cation was Ca 2+, and the major anion was HCO Due to primary pollution, the contents of Fe, Mn, and F in the study area exceeded standard values .Cl-and SO 2-4 , and Na+and Mg 2+had the same source, respectively.Compared with the fuzzy comprehensive evaluation method , the five-element connection number method based on comprehensive weight has reliable and objective evaluation results.The results obtained by the rank correlation coefficient method show that the groundwater quality has improved to a certain extent.-3 .
