摘　　要：随着沉积学研究向定量化、过程化、体系化发展,沉积正演日益受到重视。首先阐述了目前沉积正演的主要输入和输出数据,梳理了输入参数的确立方法。随后综述了沉积正演分类的方法,分类原则包括模拟原理、模拟过程数量、模拟结果类型、模拟维度、模拟尺度、忠实数据程度、是否包含源-汇系统的源区等。然后介绍了不同碎屑岩系沉积体系的沉积正演方法,包括山坡地形、河流和深水水道、三角洲、朵体和滑坡。通过介绍各个体系的某一典型模拟程序,说明这一体系需要重点模拟的沉积特征及其对应的模拟原理,并尽量涵盖多种模拟方法,扩宽对于沉积正演的认识。最后对沉积正演的发展进行了展望,认为其将向三维可视化、多过程融合、多学科融合方向发展,并建议加强计算机、数学、力学、地学的复合人才培养;加强沉积正演假想实验研究来研究沉积理论;尝试多种模拟方法;以及由应用为主转向以研发为主。More and more attention has been paid to the sedimentary forward modeling(SFM)since the study on the sedimentology is targeted toward quantification,process orientation and systematization.This review first stated the main input and output data of the current sedimentary forward modeling and sorted out the determination methods of the input parameters.Then it reviewed the classification methods of the sedimentary forward modeling,and the classification principles included principle of simulation,number of simulation processes,types of simulation results,simulation dimension,simulation scale,data fidelity and source region covering source-sink system.Subsequently,it introduced the sedimentary forward modeling methods for the different sedimentary systems of clastic series,including hillside landform,river and deep-draft waterway,delta,lobe and landslide.It also described some classic simulation programs for the individual series,indicated the sedimentary characteristics of this series to be essentially simulated and their corresponding principles of simulation and covered multiple simulation methods as much as possible to expand the understanding of the sedimentary forward modeling.Finally,it looked into the development of the sedimentary forward modeling believed it would be targeted toward the three-dimension visualization,multi-process integration and multi-discipline integration,proposed to strengthen the training of compound talents in computer,mathematics,mechanics and geosciences;strengthened the experimental study on the sedimentary forward modeling hypothesis to study the sedimentation theory;tried multiple simulation methods and shifted the application foremost to the research and development foremost.
