闽江河口为山溪性强潮河口,河口发育深受地质构造和动力条件制约。河口沉积物以陆源物质为主,在河流和海洋的相互作用下,塑造了闽江水下三角洲,并形成了复杂的沉积特征。本文根据所采集的闽江口表层沉积物的粒度分析结果,利用数学地质方法对粒度参数进行多元统计对应分析;并以此为根据,划分闽江口的动力沉积环境,进一步揭示其沉积作用的机制,为深入研究闽江口发育规律,以及为闽江口开发整治提供科学依据。
The Minjiang estuary is a mountain stream strong tidal estuary, and the estuary development is greatly restricted by the geological structure and dynamic conditions. Estuarine sediments are mainly terrestrial materials. Under the interaction of rivers and oceans, they form the underwater delta of Minjiang River and form complex sedimentary features. Based on the results of particle size analysis of surface sediments collected from the Minjiang River estuary, the paper analyzes the grain size parameters by multivariate statistical analysis using the mathematical geology method. Based on this, the dynamic sedimentary environment of the Minjiang River estuary is divided to further reveal the sedimentation effect Mechanism for the study of the development of the Minjiang Estuary law, as well as the development of the Minjiang Estuary to provide a scientific basis.
