Abstract：The all-domain digital space reference system，asa keycornerstone for the construction of Digital China，is thecore for the unified expression，integration and interaction of various spatialdata，covering multiple aspects such as geodetic reference，height reference，depth reference，gravity reference and other spatial references.Currntly，China has made significant progress in spatial reference systems，establishing a highprecision，dynamicand intelligent reference systemcovering land，sea，airand space.However，with therapid development of emerging technologies such as digital twins and the metaverse，the all-domain digital space reference system still faces many challenges in terms of accuracy，dynamics and intelligence.This paper elaborates on the development trends of the all-domain digital space reference system from multiple dimensions of integration and innovation，high precision，dynamics and inteligence，and proposes future development tasks from six aspects： geodetic reference，height reference， gravity reference，depth reference，surveying and mapping reference service system and other spatial references.The continuous advancement of the spatial benchmark wil provide solid surveying and mapping reference guarantees for the country's natural resource management，spatial planning，enginering constructionand scientific research，promotehigh-qualitydevelopmentin fieldssuchas the digital economy，smart cities and marine development，and provide important technical support for the modernization of the national governance system and governance capacity.

Keywords： global digital space reference system; geodetic reference system; elevation reference system; gravity reference system; depth reference system
