针对干旱区水资源分布不均导致部分地区存在不同程度的地下水超采现象及逐渐出现的地下水环境问题,应用耗散结构理论及熵变理论开展准噶尔盆地西北缘某研究区的地下水水质演化方向研究,依据研究区2004～2009年地下水水质监测数据建立灰色关联熵模型。计算结果表明,地下水水质的灰色关联熵整体呈不稳定状态,但灰色关联熵变化率仍在可控制阈值内,地下水水质基本朝良性方向演化。
In view of the uneven distribution of water resources in arid areas leading to different degrees of over-exploitation of groundwater in some areas and the gradual emergence of groundwater environmental problems, the application of dissipative structure theory and entropy change theory to study the evolution of groundwater quality in a study area in the northwestern part of Junggar Basin According to the groundwater quality monitoring data from 2004 to 2009 in the study area, a gray relational entropy model was established. The results show that the gray relational entropy of groundwater quality is unstable, but the gray relational entropy rate of change is still within the controllable threshold, and the groundwater quality basically evolves in the benign direction.
