| 摘 要： | 现代长江口、黄河口水下三角洲地区的海底上发育有大量规模形态各异的不稳定性现象。其中沙波和浅埋的生物气体是长江口水下三角洲发育的主要形态，而滑坡和一些冲蚀结构则是黄河口水下三角洲的主要类型；它们在分布上也有较大的差异，长江水下三角洲主要呈垂直岸线分布，而在黄河水下三角洲则表现为平行岸线分布；分析认为这些现象与其河口的沉积环境和动力机制密切相关。

| Abstract: | There are a great many different scale and shape unstable features developed on the subaqueous delta of the modern Changjiang River and Huanghe River. Sandwave and shallow buried gas are the main types on the Changjiang River subaqueous delta, but on the Huanghe River subaqueous delta, they are landslide and erosioned textured bottom mainly. And they have great difference in the distribution too: they are distributed on the Changjiang River subaqueous delta perpendicular to the coast, but on the Huanghe River subaqueous delta they are parallel to the coast. This is propably connected with esturine environment and dynamic machanisms. |
