由于地下水的过量开采 ,导致地下水资源乃至地下水环境遭到不同程度的破坏 ,引起许多与其相关的生态环境问题。为此 ,本文引用地下水环境脆弱性概念 ,并以松嫩平原为例 ,采用先进的理论和方法 ,以包气带厚度、包气带渗透系数、地下水补给强度及地下水水力坡度等为定量化指标划分不同脆弱程度地区 ,编制了为统一协调资源与环境 ,优化开采提供依据的一种新的地下水环境脆弱程度图。
Due to the excessive exploitation of groundwater, groundwater resources and even the underground water environment are destroyed to various degrees, causing many related ecological and environmental problems. For this reason, this paper refers to the concept of groundwater environmental vulnerability, taking the Songnen Plain as an example, using advanced theories and methods, such as aeration zone thickness, aeration zone permeability coefficient, groundwater recharge intensity and groundwater hydraulic gradient as quantitative indicators Dividing areas with different degrees of vulnerability, a new map of vulnerability of groundwater environment has been drawn up to provide basis for coordinating resources and environment and optimizing mining.
