本文在回顾国内外各家河口分类基础上,进一步从流域状况、河流情势、海洋情势和人为作用诸方面,分析了影响河口形态及其冲淤演变的主要因子,得到3个形态分类指标和6个水沙分类指标。运用模糊聚类分析方法进行综合定量分类,得到中国河口的四个基本类型,并首次提出潮径流量比(QF/QR)和潮径流输沙比(SF/SR)两指标作为各类河口的分类判别指标,最后对分类指标作了初步验证,且简述了各类河口的相互关系。
On the basis of reviewing the classification of each estuary at home and abroad, the paper further analyzes the main factors that affect the morphology of the estuary and the evolution of erosion and deposition from the aspects of watershed conditions, river conditions, ocean conditions and man-made effects, and obtains 3 morphological classification indexes and 6 A water and sediment classification index. Using the method of fuzzy cluster analysis, we can get the four basic types of estuaries in China by comprehensive quantitative classification. For the first time, the QF / QR and SF / SR indicators are put forward as two kinds of estuaries Classification discrimination index, and finally preliminary verification of the classification index, and outlines the various types of estuarine relationship.
