Abstract: In this paper, the mathematical model and means that can jointly solve the crustal strain continuous distribution by using varied observational data of crustal deformation are preliminar­ily studied and formed, on the basis of previous researches including the least square adjust ment model of integrally solving strain tensor of parting element in monitoring region by using varied observational data of crustal deformation, and method of estimating continuous space distribution of strain with the aid of least square collocation. Moreover, the calculated result of momtonng data is given for horizontal deformation monitoring net in Lintong region.

Key words: Observations of crustal deformation, Horizontal strain field, Least square collocation
