The organic petrologic study of Yanchang coal and carbonaceous shale of Ansai oilfield in Ordos basin indicates that the macroscopic petrologic characteristic, maceral and composite relation of the biogenic rock as well as the occurrence of organic matter can be used to better reveal the marsh paleo-geographic environment and depositional site originated by the coal and carbonaceous shale.
煤的有机岩石学特征是沉积环境良好的辅助指标之一,鄂尔多斯盆地安塞油田延长统煤和碳质泥岩的有机岩石学研究结果发现,有机岩的宏观岩石学特征、显微组分组成及其组合关系、有机质的赋存状态等能够较好地揭示煤和碳质泥岩形成的沼泽古地理环境和沉积场所,区分了原地堆积的陆地森林泥炭沼泽、覆水森林沼泽、芦苇沼泽及异地成因的漂浮沼泽等4种沼泽环境,从而为三叠系延长统形成时期古湖岸线的确定、演变以及沉积相带的划分提供了重要的参考。

人类活动对若尔盖高原沼泽的影响与对策
The study on the relationship between global warming and mire ecological system is reviewed from three aspects: ① the global warming is absoluteness;② the mire are both sources and sinks of the major trace gases,and contribute a great deal to the global warming;③ global warming will affect the area extent and distribution of mire,change scenarios and the cycling of carbon in mire.
从三个方面综述了目前关于全球变暖与沼泽生态系统的研究:①全球变暖已经成为无法争辩的事实;②沼泽是各种主要温室气体的源和汇,因而在全球气候变化中有着特殊的地位和作用;③全球气候变化又有可能对沼泽生态系统的面积、分布、功能和结构等造成巨大的影响,也可能对气候系统形成负反馈。
The comprehensive classification system of mire (CCSM) is based on the single element classification of mire, therefore it is a more complex and higher classification of mire.
沼泽是湿地的组成部分。
