| 摘 要： | 松嫩平原第四纪以来的生态环境发生了多次变迁，在地质历史时期受控于自然因素新构造运动和冰期气候旋回共同制约着第四纪生态环境演变的历史，新构造运动使平原隆起、拗陷、水系变迁和地貌重塑；东亚季风等气候因素在生态环境演化的过程中起着重要作用?并且新构造运动与气候演变具有准同步性。随着人类社会的发展，社会因素的影响逐步加强，已构成现代生态环境恶化的决定怀因素。

| Abstract: | The eco-environment of the Songnen plain has been changed many times since the Quaternary. The influence factors include natural and social factors. In the geological history, natural factors controlled the eco-environment. Neotectonism and climate cycle have pene-synchronism. They played an important role in the eco-environment change. As human society development, the influence of social factors become greater gradually. |
