厦门港湾是在各种内、外营力的综合作用尤其是在NE向、NW向、NWW向、近S-N向和NEE向等五组断裂带控制下,发育形成。的它属于潮汐汊道型港及沉溺的河口湾。塑造现代地貌发育过程的主要动力是潮流。在九龙江河口区,河流径流也起重要作用。地貌类型以堆积地貌为主,局部地段也有侵蚀、冲刷地貌(图5·2-1)。各区地貌形态分述如下。 Xiamen Harbor is in a variety of internal and external forces of the combined effect, especially in the NE, NW, NWW, near S-N and NEE direction under the control of five groups of faults, the development and formation. It belongs to the tidal port-type port and addicted to the estuary. The main driving force shaping the process of modern landform development is the trend. River runoff in the Jiulongjiang River area also plays an important role. The topography of the landform is dominated by the accumulation of landforms and the erosion and erosion of landforms (Fig. 5.1-1). The topography of each area is described as follows.
