摘要: 晚更新世以来形成的松辽分水岭是松辽平原新构造运动中最重要的地质事件之一,也是松辽平原西部脆弱生态环境恶化的重要地质因素.通过对松嫩平原分水岭的形成演化、地质及水文地质特征的研究,论述松辽分水岭的形成对松辽平原西部生态环境的影响,认为松辽分水岭是通榆、长岭、乾安、双辽一带水资源缺乏及生态环境恶化的重要地质因素,治理和保护生态环境应考虑到这一新构造运动的影响.Abstract: The formation of the Songliao divide since Late Pleistocene is one of the most important geological events of the neotectonism in Songliao Plain. It is also the significant geological factor for the deterioration of the fragile ecoenvironment in western Songliao Plain. Based on the study of the formation, evolution, geology and hydrogeology of the Songliao divide, the impact of the formation of the Songliao divide on the eco-environment in western Songliao Plain is discussed. It is concluded that the Songliao divide is an essential geological factor for the lack of water resources and the deterioration of ecological environment in the contiguous areas of Tongyu, Changling, Qianan and Shuangliao. The impact of the neotectonism should be considered in the control and protection of the eco-environment in the region.
