| 摘 要： | 利用桂林毛村地下河1983年、2007年、2008年和2009年的水化学监测数据和地下水水质资料,研究了地下河二十多年前后的主要离子浓度变化及其形成原因,并在水质评价的基础上预测其水质演化趋势。地下水地球化学分析表明：（1）地下河水中绝大部分离子和指标符合地下水质量标准（GB/T14848-93）规定的、类水质标准,地下水质量较好,但由于施肥方式以及区域环境等的变化,一些离子浓度有所升高,水质有受污染倾向。（2）pH值呈现出下降的趋势,而Cl-、NO3-、SO42-、Mg2＋、TFe、K＋、Na＋、电导率（Ec）、总溶解固体（TDS）、总硬度（TH）和碱度（Alk）升高较显著。（3）地下水离子浓度的变化主要受水-岩地质作用过程、人类活动和区域环境变化的共同影响。 |

| Abstract: | In light of the hydrochemistry and water quality monitoring data in 1983,2007,2008 and 2009 in Maocun underground river,variation of the major ions＇concentration in wet and dry seasons for the past more than 20 years are studied,and the water quality evolution trend is predicted on the basis of the water quality assessment.Underground river geochemical analysis shows that most of ions and index accord with standards Ⅰand Ⅱ prescribed by Groundwater Quality Standard（GB/T14848—93）,water quality is comparatively good.However,the ion concentration is increasing generally because of change in land use,climate and other natural conditions,and the water quality is getting worse correspondingly.Among them,Cl-,NO-3,SO2-4,Fe3＋,K＋,pH,Na＋,E,TDS,total hardness,temporary hardness,permanent hardness and total alkalinity have increased remarkably.Human activities and climate as well as geologic processes between water and rock interaction contribute to ions concentration change,and human activity is the main influencing factor. |
| Keywords: | karst underground river ion concentration change water quality evolution tendency Maocun GuiLin |
