Abstract: As the core contents of natural and human factors, there exist a strong spatial correlation and interaction relationships between geological relic and ethnic cultural. The paper proposed a universal quantitative research program of spatial relationships between geological relics and ethnic cultural resources from the aspects of quantity spatial relationship, quality spatial relationship and spatial coupling relationship, and taking northern Guangxi as typical research area,for these two kinds of resources have obvious advantages. The results show that the quantitative spatial correlation index value R between geological relics and ethnic cultural resources in northern Guangxi is 0.357, the close quantity spatial relationship is distinctness from significance testing; The higher the coupling degree value CI is, the more closely the quality spatial relationship between geological relics and ethnic cultural resources are. The average CI in northern Guangxi is 0.95, and achieved excellent coordination level, which indicated that there exist a very high quality space correlation between the two. The higher the evaluation value of coupling resources D is, the more closely the spatial coupling relationship between geological relics and ethnic cultural resources are. The average D in northern Guangxi is 0.93, among these districts, Yangsuo, Qixin, Diecai, Luzai,Yufeng and other 16 counties are high, but Pingle, Liunan, Liubei,Chengzhong and other parts of counties are low, which indicates a great comprehensive level of the spatial coupling relationship but lack of balance of distribution.
