摘要
地表水与地下水同出一源，地表水与地下水多次转化是我国干旱区水资源的主要特点，因此研究干旱区总水资源计算不仅具有理论意义，也有重要实践意义。根据估算，干旱区总水资源量为１０４０．４×１０８ｍ３／ａ，由于干旱区地表水与地下水，从山区至平原不断转化，地表水与地下水资源总量之和，扣除总重复量，才是真实总水资源。
The main features in the arid zone of China are distinguished as follows:each bas in has a centripetal water system;surface water and groundwater come from the same source and interchange between groundwater and surface water is frequent.Research on calculation of total amount of water resources in the arid zone is not only of academic significance but also of practical signifcance.According to recent calculations,the total amount of annual water resources in China's arid zone is 104.04 billion m 3.
