| 摘 要： | 盐阜平原地处苏北平原东部.全新世以来,由于海面变化使本区地理空间结构经历了三个阶段的演化:早全新世,海面上升,本区成为浅海环境,空间结构较为单一.中全新世,海面稳定,古砂堤发育,砂堤两侧形成了泻湖与浅海的二元结构,其西侧的里下河区成为封闭的泻湖,而东部仍以浅海为主.晚全新世,海面下降,本区完成了由海到陆的演变过程,形成了盐阜平原地理空间三元结构的格局:北部为黄淮平原的一部分;西部里下河地区湖泊沼泽面积不断缩小,演变为里下河平原;而东部海岸东迁,形成广袤的滨海平原.

| Abstract: | Yanfu plain is situated in the east of North Jiangsu plain.Influenced by changes of sea level,the evolution of the Palaeogeography have gone through three stages here since Holocene.It became a shallow sea because of the transgression of sea and sea level was up in the early Holocene,and the space construction was comparatively single.During the middle Holocene,the old sandbars formed as sea level had remaind relatively steadiness,and the two-element construction constituted by lagoon and shallow sea formed... |
