Based on the 87 standard sections and 529 supplementary sections，and the analyses of the Permian distribution pattern, the petrologic characters, the characters of sedimentary structures, the palaeoclimate, palaeoecology and palaeoenvironment data, the palaeogeographical features of the Permian in northern China are reconstructed. In the Early Permian, mainly the Jiamusi，the Aierguna，and the TarimDunhuangQilianInner Mongolia oldlands were developed; marine sediments were distributed in the Songliao marine facies area, the North China relic estuarine area，the western Qaidam relic estuarine facies area and the southern JunggarTurpanHamiBeishan relic marine facies area, and also the western Tarim carbonate platform facies and the central Junggar fluviallacustrine facies were developed. In the Middle Permian, the oldlands of the Early Permian still existed and the northern North China oldland was obviously reduced in size. The southern margin of the Junggar BasinTurpanHami area was uplifted to become land. The marine facies was only developed in northeastern China and southern Qilian areas. The fluviallacustrine facies was widely developed in the North Chinanorthern Qilian area. The Tarim Basin was dominated by continental clastic rocks, the Junggar Basin by fluviallacustrine deposition, and the Beishan relic sea basin by deposition of volcanic clastic rocks. In the Late Permian, marine facies only occurred in southern Qilian area and the other areas were all characterized by continental deposition. The northeastern area was dominated by the continental and lacustrine facies. The North Chinanorthern Qilian area was mainly covered by fluviallacustrine sediments. The whole Tarim Basin was a fluviallacustrine deposition  and the JuggarTurpanHami basins were dominated by fluviallacustrine deposition.
