论我国古代对河流水文学与动力学的认识——以长江武汉段江面人工干预洲港变迁事例为中心

Discussion on the Knowledge of Hydrology Mechanics about Rivers in Ancient China——Take the instance of manual intervention continent port to Yangtze River in Wuhan section vicissitude as the center

科技的发展是与人们对自然环境的观察、认识和利用相伴而生的,人类科技史离不开其自身的社会经济生活。以长江武汉段江面人工干预洲港变迁事例为中心,论述了我国古代对河流水文力学的认识。古人对河流江心中沙洲的淤涨坍消现象及其水文力学原理这一问题的认识,大致经历了从对沙洲淤涨现象的观察和描述,到进一步阐述沙洲淤消演替原理,再到运用沙洲淤消演替原理人为干预沙洲的演变,并对其进行经验总结与理论提升这样一个发展过程。科技史的书写,还取决于我们对历史文献的掌握程度。新材料的发现或发掘,往往可能改写科技史。

The developments of science and technology are always concomitant with observation, cognition and utilization of people. The history of science and technology of men lies on the society and living of themselves. This paper circled on the case of man- made changes of the alluvions and the ports of Yangtze River near Wuhan. The thesis elaborated the cognition on hydrological dynamics in ancient China. The course Comes through several phrases from only the simple depiction to the expatiation of principle to the exertion of principle, and etc. How to write the history of science and technology also rely on the number of literature we mastered. The history sometimes will be rewritten because of discoveries of new datum.
