DING Shi-jun~①,JIN Xiang-sheng~②(①School of Geodesy and Geomatics,Hubei,Wuhan 430079;②Yellow River Conservancy Technical Institute,Henan,Kaifeng,475000)  
Solutions of ill-posed problem in surveying adjustment are most ascribed to problem of extremum on the principle of Tikhonov regularization.And choice of regularization parameter is very important.In this paper,solution properties are discussed and some choice methods of regularization parameter on ill-posed problem are summarized.In the last section of this paper,some choice methods are synthetically analyzed and compared by two examples,and the applicabilities and characteristics of some choice methods are given.
