Abstract: Objectives In order to discusses the evolutionary process of basin-orogeny systems in the North China Basin and surrounding orogens in the Late Paleozoic，conduct research on the U-Pb age characteristics of Late Paleozoic detrital zircons in the North China Basin and their response to the surrounding orogenic belts.  Methods the published U-Pb age data of the Late Paleozoic detrital zircons in the North China Basin were collected. By conducting large-scale data collation and statistics， and combined with the evolution process of surrounding orogenic belts， the impact of tectonic activity in the margin orogenic belt on the North China Craton Basin was analyzed. Results The results showed that， the detrital zircon from the Benxi Formation of the North China Basin in the Late Carboniferous had two major age group peaks at 310， 440 Ma. The detrital zircon from the Taiyuan Formation-Upper Shihezi Formation of the Early Permian had five major age group peaks at 310， 300， 440， ~1 850， ~2 500 Ma. The detrital zircon from the Shiqianfeng Formation of the Early Permian had five major age group peaks at 260， 310， 440， ~1850， ~2 500 Ma. In the Late Carboniferous， the main provenance of the North China Basin was thought to be the Qinling Orogenic Belt. In the late Early Permain， the sediments from Inner Mongolia uplift were distributed in the northern margin of the North China Basin； the sediments of the Inner Mongolia uplift prograded to the southern of the North China Basin， the tectonic pattern had been transformed from high in the south to high in the north in this time. Qinling Orogenic Belt provided sediments to North China Basin again in the Late Permain， indicated the uplift of the southern of the basin. Conclusions The evolution of the provenance indicated the continuously enhanced orogenic movement of Xingmeng Orogenic Belt of the northern of North China， and the tectonic transformation of extension-subduction of the Mianlue Ocean in Qinling Orogenic Belt of the southern of the North China.
