| 摘 要： | 七里海有中国第一大潟湖之称,多数学者认为七里海外的海岸沙丘群是在滨外沙坝的基础上发育形成的。研究认为,七里海外的海岸沙丘群是在末次冰期时期风成沙丘群的基础上演化形成的继承性沙丘综合体。七里海也不是科学意义上的潟湖,它没有形成海岸沙坝这一潟湖形成的过程,其前身是晚更新世末期由风暴活动形成的风蚀洼地。应加强七里海外海岸沙丘群的形成、发育类型及演化过程的研究,从多角度探究七里海外海岸沙丘群的演化机理和发育趋势。

| Abstract: | Qilihai was called the largest lagood in China,and many scholars suggested that the coastal dunes outside the Qilihai lagoon developed from the offshore sand bars.It is concluded from our study results that the coastal dunes outside the Qilihai lagoon are inherited dune complex formed from the eolian dunes in the last glacial period.There were no coastal sand bar formation process for generating the Qilihai lagoon,and its predecessor is a deflation low-lying land formed during the last stage of late Pleistocene,so the Qilihai lagoon is not a lagoon scientifically.The study on the formation,development type and evolution process of coastal dunes outside the Qilihai lagoon shall be strenthened so as to get a deep-going understanding of the evolution mechanism and development trend of coastal dunes outside the Qilihai lagoon. |
