上海地区地貌发育的差异性

The Varied Landscape Formation in the Area of Shanghai

上海位于长江三角洲的东南前缘 ,由于本地区的不同的沉积环境 ,使得在本地区出现了地貌发育的差异性 ,这些差异性表现在上海地区现在各种微地貌之中 :东北部地区是典型的三角洲发育 ;东部地区是三角洲发育的伴生体系———滨海平原 ;东部和南部沿海地区发育的是潮坪 ;西部地区总的来说是湖沼平原发育 ,但由于它本身发育条件的差异性比较大 ,从而在内部又有着不同的地貌发育 ,发育了湖滨平原、湖沼洼地、海积—湖积平原。

The difference in the conditions for sediment processes caused the difference in the geogmophy formation in the area of Shanghai: typical delta in the northeast, delta-accompanying system in the east, low tiding land in the coastal area in the south and east, a general lake-and-bog plain in the west. Those general patterns have again been subject to the influence of the specific situations in their micro-formations
