松嫩平原南部地下水流场特征及环境地质问题研究

Characteristics of groundwater flow field and environmental geological problems in southern Songnen Plain

松嫩平原位于东北地区中部,松辽平原北部,是我国大型商品粮生产基地和重要的能源、化工、汽车及机械制造基地,是东北老工业企业主要分布区之一。地下水作为水资源的一部分,在松嫩平原的社会经济发展和维持生态环境中发挥着不可替代的作用,随着经济的发展和人口的增长,水资源供需之间的矛盾越来越突出,生态环境压力越来越大,许多工作与地下水有直接关系的环境问题已经影响到了社会经济的发展,甚至于人类的长期生存。特别是松嫩平原南部原有的水文地质调查数据和成果已无法满足当代地下水资源开发和地质环境保护与管理的需要,亟街更新。通过统测点调查及地下水位统测,基本查明地下水流场、稳定与非稳定降落漏斗的数量及其特征,并提出易引发的环境地质问题。

Songnen Plain,located in the middle of northeast China and the north of Northeast China Plain,is a large-scale commodity grain production base and an important manufacturing base of energy,chemical,automobile and machinery.Groundwater,as a part of water resources,plays an irreplaceable role in the social and economic development of Songnen Plain and in maintaining the ecological environment.With the development of Economy and population,the contradiction between the supply and demand of water resources becomes more and more prominent,the pressure of ecological environment is becoming more and more serious.Many environmental problems directly related to groundwater have affected the development of social economy,even the long-term survival of human beings.In particular,the original hydrogeological survey data and achievements in southern Songnen Plain can not meet the needs of contemporary groundwater resources development and geological environment protection and management.Based on the survey of survey points and groundwater level,the number and characteristics of groundwater flow field,stable and unstable landing funnels are found out,and some environmental geological problems are put forward.
