Abstract: This article was a keynote speech by Prof.Yu Jing –yuan at the Fifth Substitution Symposium of Committee members of the System Engineering Society of China. Metasynthesis is a systematic method that can be used to solve the problems of complex systems and complex huge systems .It was established between late 1980s and early 11990s by Qian Xue- sen ,a well –known scientist in China .To make his report helpful for future research and application ,the author expounds meta-synthesis from the perspectives of method, theory, technology, and application in a profound but easily understood way.The direction of synthesis and integration is not only a scientific theoretical problem,but also a technical practial problem. The editors of the journal believe this report has a guiding function for the planning and construction of our national comprehensive transportation network,so it is presented to readers here.

Key words: meta-synthesis, Qianxue-sen, complex systems and complex huge systems, planning of comprehensive transportation network

摘要： 本篇文章是于景元研究员在“中国系统工程学会交通运输系统工程专业委员会第五届理事会暨中国综合交通运输发展研讨会”上的大会发言稿。综合集成方法和综合集成思想是我国著名科学家钱学森在20世纪80年代末至90年代初提出的一种系统方法，用于处理复杂系统和复杂巨系统问题。作者分别从方法、理论、技术与应用几个层次上，深入浅出地对综合集成方法进行了阐述，其目的是为了今后有利于对综合集成方法的研究和应用。综合性和整体化的方向，不仅是科学层次上的理论问题，也是技术层次上的应用问题，本刊认为该发言对我国综合交通网的规划和建设有重要的指导作用，在此发表，以飨读者。
