吐鲁番市水资源现状及水质特征分析

目的]分析吐鲁番市水资源现状及水质特征。方法]首先介绍了吐鲁番市水资源现状,然后参照《生活饮用水卫生标准》(GB5749-2006)和《农田灌溉水质标准》(GB5084-2005),对坎儿井水、机井水、渠水、村井水和艾丁湖水等5种水样和2种土样(分别用坎儿井水、机井水灌溉的土壤)进行水质分析和土壤质量分析。结果]村井水和艾丁湖水的氯化物和硫酸盐含量、机井水和渠水中的硫酸盐含量均超过了《生活饮用水卫生标准》的标准值;而坎儿井水中氯化物和硫酸盐含量都符合该标准。用坎儿井水灌溉的土壤盐化程度为轻度盐化,土壤有机质含量较高;用机井水灌溉的土壤盐化程度为重度盐化,土壤有机质含量较低。结论]坎儿井水更适合于作农田灌溉用水。

Analysis of Water Resources and Water Quality Characteristics in Turpan City

Objective] The study aimed to analyze the current situation of water resources and water quality characteristics in Turpan City. Method ] Based on the analysis of water resources in Turpan City, five kinds of water samples from a karez, motor-pumped well, canal, village well and Aydingkol Lake as well as two types of soil samples irrigated by the karez water and motor-pumped well water were analyzed according to Drinking Water Hygienic Standards （GB5749-2006） and Standards for Irrigation Water Quality （GB5084-2005）. Result l Chloride and sulfate content in the water from the village well and Aydingkol Lake were higher than the national standard values ,as well as sulfate content in the mot0r-pumped well water and canal water. However, chloride and sulfate content in the karez water were lower than the national standard values. The soil irriga- ted by the karez water was salinized slightly,and organic matter content was higher; the soil irrigated by the motor-pumped well water was salin- ized seriously, and organic matter content was lower. Conclusion] The karez water is more applicable to farmland irrigation.
