Summary:The invention relates to an elevation measurement method and system for continuously tracking lifting of a monitoring point. The method comprises the following steps: setting a point A and a point B as working base points and setting points 1, 2, 3, 4... n as monitoring points; acquiring initial elevation values HA and HB of the working base point and initial elevation values Hi of the monitoring points through a precision level gauge, wherein i in the Hi represents the number of each monitoring point; acquiring the vertical coordinate of each monitoring point last time through the laser alignment displacement meter sensor and recording the vertical coordinate as yi '; obtaining the ordinate of each monitoring point at this time and recording the ordinate as yi ''; calculating an elevation change value Sigma Delta i according to the ordinate yi ''of each monitoring point at this time and the ordinate yi 'of each monitoring point at the last time; and calculating the actual elevation Hi'according to the last e
