当前全球气候处于第四纪大冰期中的冰期与间冰期之间，人类文明的发展要求对这一过渡期气候及其引起的环境变化趋势进行预测。早二叠世全球气候（阿瑟尔期-亚丁斯克期变暖，晚空谷期变冷）与当前人类所处的气候演化阶段相似，为了揭示冰期-间冰期环境-气候演化特征，为当前全球环境-气候变化预测提供依据，以华北地台早二叠世海陆过渡相煤系典型剖面为研究对象，建立煤系沉积-层序地层模式、等时地层格架及其对应的海平面变化曲线；采用有机质碳同位素（δ13CO）、有孔虫氧同位素（δ18Oc）、化学蚀变指数（CIA）、矿物蚀变指数（MIA）等参数恢复煤系高分辨率气候演化史，总结层序格架内冰期-间冰期环境和气候演化特征。结合早二叠世全球古气候、海平面和古大气成分变化以及南方冈瓦纳冰原融化等方面前人研究成果，围绕对煤系沼泽、碳酸盐岩和陆源碎屑3种矛盾体系沉积驱动力的分析，总结和提出冰期-间冰期华北地台环境-气候耦合作用机制。

The current global climate is between the ice age and interglacial period of the 4th Great Ice Age, and the human civilization development requires a forecast on the global climate in the period and the variation tendency of the environment under the forecasted climate change. The global climate in early Permian epoch (warmer in Arthur to Artinskian, and colder in late Kungurian age) was similar to the current climate variation. To reveal the environment-climate evolutionary characters and coupling effects in the ice age and interglacial period, the essay, to provide theoretical reference on the current global environment-climate change forecast, established the coal sedimentary and stratigraphic sequence mode, isochronal stratigraphic framework and the eustatic sea level change curves. The research, taking the classical outcrop and borehole sections of the transitional facies in early Permian epoch in North China Platform as subject, repconstructed the high resolution climate evolution history in coal series by key parameters ofδ13CO, δ18Oc, CIA and MIA, and summarized the environment-climate evolutionary characters of the period in sequence stratigraphic framework. With reference to the earlier research results in the global climate, sea level changes and variation of atmospheric composition in the early Permian epoch and melting of southern Gondwana Ice Field, the essay summarized and proposed the coupling effect of environment and climate in the ice-interglacial period in Northern China Platform after detailed analysis of the sedimentation driving force in the environmental evolution in the contradictive system among coal swamps, carbonatite, and terrigenous detrital.
