广东东部沿海的潮汕地区,是由韩江、榕江、练江,黄岗水等四条河流自西或西北方向携带大量泥沙在下游堆积而成,故一般通称的潮汕平原实际上由韩江三角洲,榕江冲积平原、练江冲积平原、黄岗水冲积平原等四部份共同组成。其中韩江三角洲和榕江平原的面积分别为1041平方公里和996平方公里,是本区的主体部份。但两者的展布形态则不同,前者以潮安为三角洲的顶点,河道渐成树枝状分汊,注入南海,属于较典型的扇形三角洲;后者则以干流注入牛田洋海湾,然后汇入南海,属于港湾式三角洲(习惯上称为榕江平原)。各平原之间常有丘陵台地为界,从而组成本区有山有水的地貌景观。
The Chaoshan area along the eastern coast of Guangdong is formed by four rivers, including the Hanjiang River, Rongjiang River, Lianjiang River and Huanggang River, which carry a large amount of sediment from the west or northwest and accumulate in the lower reaches. Therefore, the Chaoshan Plain, commonly known as the Pearl River Delta, , Rongjiang alluvial plain, Lianjiang alluvial plain, Huanggang alluvial plain composed of four parts. Among them, the areas of the Hanjiang River Delta and Rongjiang Plain are 1,041 square kilometers and 996 square kilometers, respectively, which is the main part of this district. However, the distribution pattern of the two is different. The former takes the Chaoan as the apex of the delta, and the channel gradually dendrites into the South China Sea, belonging to the more typical fan-shaped delta. The latter is injected into the Niutianyang Bay by a dry stream and then imported South China Sea, belonged to the Harbor Delta (used to be known as the Rongjiang Plain). Hilly plains often between the plains for the community, thus forming a mountainous area in this area landscape.
