摘要： 破译古生物形态与功能之间的关系，是重建古生物生活方式的重要内容，对确定古生物的进化过程、分类位置及相应古环境信息都具有极为重要的意义。然而，难以找到可作对比的现生生物，同时缺乏反映某种功能的定量描述，是制约古生物形态功能分析的最大障碍。计算流体力学（computational fluid dynamics, CFD）采用数值方法在计算机上求解流体力学问题，已发展为目前流体力学研究的主要手段之一，正逐步应用于古生物学形态功能分析领域。通过对生物学形态功能分析的发展史和CFD的基本原理进行综述，对CFD在古生物学形态功能分析的一般流程进行解析，并对CFD在古生物学形态功能分析中的应用进行概述，提出CFD在论证古生物长期存在的功能学和生态学假说方面具备极大的潜力，最后对CFD在古生物学中的应用前景进行展望，指出CFD为化石生物形态功能的关联性分析和性能检验开创了新的研究方向，今后CFD应成为古生物学家求证化石生物功能学相关问题的重要方法和有力工具。

Abstract: Deciphering the relationship between the morphology and function of palaeontology is an important part of the reconstruction of palaeontological lifestyle, which is of great significance for the determination of palaeontological evolution process, taxonomic position and paleoenvironmental information. However, palaeontological groups often lack quantitative data about some behavioral function, and it is difficult to find living organisms which are similar to the study objects. That has become the biggest obstacle for their morphological function analysis at present. Computational fluid dynamics (CFD), a tool for generating quantitative data based on numerical simulations of fluids and solid, has been able to easily solve any two-dimensional and most three-dimensional flow fields, including paleomorphological functional simulation and analysis. In this paper, the history of biological morphological function and the brief the basic principle of CFD were carried on, the general flow of functional analysis of CFD in paleontology and the application of CFD in paleontology form function analysis were summarized. CFD has great potential in sovling the argumentation of long-standing paleontology function and ecology hypothesis. Finally, the application of CFD in paleontology foreground was prospected. CFD created a new research direction for fossil biological form function correlation analysis and performance test. In the future, CFD should become an important method and powerful tool for paleontologists to find out the problems related to fossil functional biology.
