Abstract

How to quantitatively evaluate the groundwater environment is an important question. In this paper, the groundwater environment was defined by considering both groundwater quantity and quality, and taking human activities into consideration. Two multiobjective comprehensive evaluation methods were applied to quantitatively evaluate the groundwater environment. Factors influencing the groundwater environment were selected as evaluation indices, which may offer a new approach to studying their influence. Tongliao, where the problems of the groundwater environment are serious, was taken as the study example. According to the results, more than 50% of zones of the groundwater environment in 2010, 2015, and 2018 were Grade II, and the status of most zones remained stable from 2010 to 2018. This study aids in the understanding of the groundwater environment. Numerically evaluated results make assessment of the groundwater environment simple and intuitive. Selected evaluation indices should fully reflect the characteristics of the groundwater environment as comprehensively as possible. The weights should be determined based on subjective and objective methods to eliminate the influence of variability. Additionally, the division of administrative areas should be taken into account. Finally, the influence of human activities can be reflected according to indices that are sensitive to human activities and their variability.

摘要

如何定量评价地下水环境是一个重要的问题。本文通过考虑地下水的数量和质量，并考虑人类活动来定义地下水环境。运用两种多目标综合评价方法对地下水环境进行定量评价。选择影响地下水环境的因素作为评价指标，可能为研究其影响提供一种新途径。以地下水环境问题严重的通辽市为研究实例。根据结果​​，2010年，2015年和2018年的地下水环境区域中，超过50％属于II级区域，大多数区域的状况在2010年至2018年期间保持稳定。这项研究有助于理解地下水环境。数值评估的结果使对地下水环境的评估变得简单而直观。选定的评价指标应尽可能全面地反映地下水环境的特征。应基于主观和客观方法确定权重，以消除可变性的影响。此外，应考虑行政区域的划分。最后，人类活动的影响可以根据对人类活动及其可变性敏感的指标来反映。选定的评价指标应尽可能全面地反映地下水环境的特征。应基于主观和客观方法确定权重，以消除可变性的影响。此外，应考虑行政区域的划分。最后，人类活动的影响可以根据对人类活动及其可变性敏感的指标来反映。选定的评价指标应尽可能全面地反映地下水环境的特征。应基于主观和客观方法确定权重，以消除可变性的影响。此外，应考虑行政区域的划分。最后，人类活动的影响可以根据对人类活动及其可变性敏感的指标来反映。
