摘要
本文从地貌、水系形式论述江汉盆地新构造的特点。指出江汉盆地为一继承性沉降盆地,同时新构造又具新生性。新构造运动的类型有差异升降运动、掀斜和拗折运动。江汉平原第四纪植物孢粉组合反映气候冷暧交替。鄂西山地发育了山谷冰川,平原区为湖河交错,受新构造运动影响,云梦泽逐渐解体。
According to geomorphic and drainge pattern,the characteristics of neotectonics in Jianghan Basin was discribed. It is presented that Jianglian Basin is a continuous downthrow basin,but the neotectonics in the basin has neogenic characters.The neotectonic movement types are divided into differential up-down motion,tilted and break down movement.The spore-pollen assemblages in Jianghan plain indicate that the climate had changed between cold and warm alternatively.Valley glacier was developed in the mountains of western Hubei,while plainareas were rich in rivers and lakes.Yunmeng Swamp,as affected by neotectonic movement,is disembodied gradtlally.
