介绍了ＧＰＳ技术在水库测量中的应用，它具有快速、精确等特点。同时应用地理信息系统，根据实测数据求出各单元的体积，然后计算出各级高程下的库容。该方法彻底改变了过去采用求积仪法在地形图上量算库容的历史，大大提高了库容曲线的精度。该方法在青海龙羊峡水库、广东青溪水库和福建沙溪口水库得到应用，成果非常理想，具有推广价值 The application of GPS technology in reservoir measurement is introduced. It has the characteristics of fastness and precision. At the same time the application of geographic information systems, based on measured data to find the volume of each unit, and then calculate the reservoir at all levels of elevation. The method completely changed the past history of using plotimeter method to calculate the capacity of the topographic map, greatly improving the accuracy of the storage volume curve. The method is applied in Longyangxia Reservoir in Qinghai Province, Qingxi Reservoir in Guangdong Province and Shaxikou Reservoir in Fujian Province. The result is very satisfactory and has the promotion value
