摘要
论述了松嫩平原第四纪以来生态地质环境的变迁过程并对其演化机制进行了初步探讨。新构造运动是本区生态环境变迁的主要内动力 ,直接影响地形起伏和地貌形态 ,制约水系的变迁和沉积环境的演化。东亚季风作为新构造运动的间接产物 ,对本区气候的波动产生重要影响。新构造运动和东亚季风共同控制着本区第四纪以来生态地质环境的演化历史。
This article discussed on the evolvement process of water systems, sediment environment, climate and entironment in the Songnen plain from the Quarternary. The authors discovered that both Neotectonism and climate cycle have pene-synchronization. They may be controlled by a higher inner power mechanism. Neotectonism directly influence relief shape which govern changes of water systems, sediment environment, climate and entironment. East-Asia Monsoon which is indirect product of Neotectonism influence climate change in the district greatly. Neotectonism and East-Asia Monsoon control entironment evolvement of the district from the Quarternary together.
