辽河流域平原区地下水生态水位及水量调控研究

对辽河流域平原区地下水生态水位及水量调控进行了初步研究,界定了地下水生态水位概念、分类及其特征,论述了该领域的研究现状。以辽河平原为研究对象,阐述了研究区地下水生态水位的确定原则、依据及地下水生态调控量的计算方法,其中地下水生态调控量采用情景分析方法,通过设置两种情景,构建了两套地下水生态标准,计算出地下水生态调控量。研究结果表明:通过确定地下水的生态水位,并将其与实际地下水水位埋深进行比较,结合水文地质参数,可以计算出地下水生态调控量。

Ecological groundwater level and quantity regulation in plain region of Liaohe Watershed

With plain region of Liaohe Watershed as an example,the conception,classification,and characteristics of ecological groundwater level were discussed,and the current situation of the research in this area was described.The principle for determining the ecological groundwater level of this region was expounded,and the calculation of the quantity of ecological groundwater regulation with the scenario analysis method was introduced,in which two sets of groundwater ecological criteria were constructed by setting of two scenarios for the calculation.The result shows that,in combination with the hydrological and geological parameters,the quantity of ecological groundwater regulation can be obtained by determination and comparison of the ecological groundwater level with the actual embedded depth of groundwater in this region.
