摘要
结合阿克苏地区25眼地下水观测井2000-2020年地下水埋深及矿化度观测资料,对阿克苏流域近20 a地下水埋深及矿化度变化规律进行分析。结果表明:近20 a阿克苏流域地下水埋深总体呈现递增变化,年平均递增率为0.063 m/a,从上游到下游地下水埋深递变幅度逐步加大。地下水埋深呈现明显的季节变化特征,7月份由于降雨补给较大其地下水埋深最低。近20 a以来阿克苏流域地下水矿化度总体变化平稳,矿化度均值为2.32 g/L。
Based on the observation data of groundwater depth and salinity from 25 observation wells in Aksu area from 2000 to 2020,the change law of groundwater depth and salinity in Aksu basin in the past 20 years is analyzed.The results show that in the past 20 years,the groundwater depth in Aksu basin has shown an overall increasing change,with an annual average increasing rate of 0.087 m/a,and the increasing degree of groundwater depth from the upstream to the downstream has gradually increased.The groundwater depth shows obvious seasonal variation characteristics.In July,the groundwater depth is the lowest due to the large rainfall recharge.In the past 20 years,the salinity of underground water in Aksu basin has changed steadily,with an average of 2.32 g/L.
