    Abstract: This paper  reviews  the progress  and the  theoretical  achievements  in  stress-strain  calculation using geodetic measurements over  the past  ten years  and profiles  domestic and  international  research with a discussion  about  the  relationshi p between the gravit y and stress-strain  fields.Studies  and applications  of  stress-strain  inversion using geodetic data are  summarizedand the outstanding problems are  anal yzed.The  development of  geodesy technolo gy will  continue pushing for  the perfection of  the inversion  theor y of  the  crustal  stress-strain  field  using geodetic data.We  suggest  that  the  anal yticall yelasticvisco  elastic and elasto plastic  crust models relating ground gravit y to  the  stress-strain  field can be completel y articulated  and applied.We  also  conclude  that  studies  concerning the  relationshi pbetween spatio-temporaltectonic  stress-strain  fields  and seismic  stress  tri ggering in  the  crustas wellas  joint  inversion  for  spatio-temporal  tectonic  stress-strain  fields  with multi-source datashould be de-veloped.
