| 摘 要： | 地球科学前沿研究为社会服务是一个永恒的主题，这在当前全球化背景下尤其迫切.古生物学作为一个受人瞩目的精品学科，在向地球生物学发展过程中，其服务领域正不断地拓展和创新.系统地总结了当前地球生物学在全球变化和油气资源两大领域的应用与拓展，以及在关键带和深地两大领域的创新性发展.在全球变化领域，藻类、古菌、细菌等地质微生物的脂类不仅能够用于估算古温度，还可以记录干旱等极端古气候事件，从而实现古温度与古降水信号的分离.地球生物学已经从探索生物对环境的响应深入到生物对环境的作用.地球生物学也在评价烃源岩、储层等常规油气资源领域得到广泛的应用，但当前其更重要的应用表现在页岩气等非常规油气资源领域，包括地质微生物形成页岩中的纳米孔隙，形成易于压裂的长石、石英等矿物.在关键带研究领域，地球生物学可以解剖碳循环与水循环之间的内在联系.聚焦于地质微生物功能群的关键带地质微生物调查，不仅可以查明污染物的分布和污染程度，还可以为环境修复提供技术方法.而在深地研究领域，为拓展对地下空间的利用，需要充分利用地下工程对地下微生物开展调查和研究，以查明地下环境中有害或者有益的微生物功能群分布及其地质作用.

On Development from Paleontology to Geobiology: Overview of Innovation and Expansion of Application Fields |
| |
| Abstract: | To serve the society has always been the main goal for all the scientific research of geosciences, which is of particular significance in the globalization contexts. Paleontology, an important conventional academic disciplinary branch of geology, has already developed into a new stage of geobiology, which greatly expands the application fields closely related to the development of the society. In this paper, it presents an overview of the innovation and expansion of the application fields, including the expansion in the geobiological application of global change and fossil fuels, and the geobiological innovation in critical zones and deep Earth. Microbial lipids can be used not only as the proxies of paleo-temperature, but also as the indicators of paleo-hydroclimate, which makes it possible to independently reconstruct the paleo-temperature and paleo-hydrology in Earth history, a critical issue of the past global change. Geobiological archives could also help decipher the environmental settings of both the origin of life and the biotic evolution, and in particular geobiological records could help identify the biotic impact on environmental conditions. Geobiological methods could be applied to evaluate the hydrocarbon source rocks and the reservoir strata which were less explored by paleontology. Geobiology can be of great help in the investigation of non-conventional petroleum and gas, including the microbially-induced nanometer pores and minerals such as quartz and feldspar in gas-bearing shales. Molecular and isotopic geobiological techniques and methods are now used to investigate the causal relationship between carbon cycle and water cycle in a variety of critical zones of Earth surface systems. The investigations on the distribution of some geomicrobial functional groups in the critical zones will help understand the distribution of the environments polluted and help recover the polluted areas. Recently-proposed Deep Earth Plan aims to extend the habitable underground space, and this expansion awaits the investigations on deep subsurface microbial communities which may greatly ameliorate or even deteriorate the underground environments. |
