摘　　要：丁村湖是在串珠状古汾河贯通以后形成的 ,受气候与构造的影响 ,第四纪时出现过多次的伸收扩缩过程 .早更新世时 ,丁村湖所在地为三门湖的一部分而存在 ;中更新世早、中期三门湖面积缩小 ,汾河贯通 ,柴庄隆起逐渐形成 ,丁村湖出现 ;中更新世末期晚更新世初 ,受末次间冰期气候转暖的影响 ,是丁村湖面积最大时期 ;到了晚更新世末期 ,随末次冰期的来临 ,湖泊收缩 ,仅在低洼地区或拗陷中心地区以遗迹湖的形式残留一些小湖 ,有些还延续至全新世 .DingCun Lake formed after the Ancient Fenhe River ran through. Under the influence of the Neotectonic movement and the paleoclimatical change, the climate was either warm or cold in the Q. And the area of the DingCun Lake changed for some times. Q 1, Dingcun Lake existed as a part of San Men Lake; Q 1 2-Q 2 2, the lake′s area became small; and Q 3 2-Q 1 3, the lake became larger again because of the climate of the last Interglacial. At the late of Q 3, the lake became smaller and smaller, then disappear with the last Ice Age coming. Only in some sinking centers and lower areas are there some little lakes as remains, some which have been lasted to Q 4.
