摘　　要：我国西部部分重要湖泊测量属国家水利前期工作项目,西部地区湖泊众多,多数湖泊位于高海拔地区,因为地处偏远,人迹罕至,交通条件不便,自然环境恶劣,导致大多数湖泊未开展过系统科学的测量工作,湖泊基本情况不清,历史资料空白,不能满足湖泊开发治理、生态环境保护、水资源管理、科学研究等工作需要,因此国务院决定开展此工作。概述了西藏五大湖泊测量中的控制系统解决方法,采用世界IGS跟踪站与湖泊控制网站点进行联测得到精准的控制点的平面坐标,解决了测区无平面坐标引据点的问题;采用基于EGM2008地球重力场模型解算出湖泊控制网站点的高程,解决了测区高程引据点少的问题。控制成果经过了验证,对西部部分重要湖泊测量起到了决定性作用。The survey of some important lakes in western China is a national water conservancy prophase project.There are a large number of lakes in the western part of China and most of the them are located in high-altitude areas.Because of their remoteness,uninhabited and inconvenient traffic conditions and harsh natural environment,no systematic scientific surveying work was conducted for the most lakes.These lakes are unclear in basic condition and blank in historical data and cannot meet the requirement of lake development and management,ecological and environmental protection,water resources management,scientific research and other work.Therefore,the State Council decided to carry out the survey work.In this paper,the solution of hydrological survey control system of five major lakes in Tibet is summarized.Due to without plane coordinate leading position in surveying area,the combined survey by using the world IGS tracking station and the lake control site was innovatively adopted to determine the plane coordinates of the accurate control points.In the light of less elevation points in the survey area,EGM2008-based gravity field model was innovatively adopted to calculate the elevation of the lake survey control site.The results have been verified,which play a decisive role in the survey of some important western lakes.
