THE IRREVERSIBLE PROCESS INGROUNDWATER SYSTEM

摘要

By reviewing the evolving history of the groundwater system in a city area, it is discovered that the advent of a newrnsystem structure is achieved through the process of mutation, and the whole process is irreversible; it is further believed that, underrnthe influence of continuous artificial exploitation, the groundwater system makes necessary structural adjustments to meet therndemands imposed on the performance of the whole system; furthermore, through evolvement, the whole system degenerates into arnthermo-dynamic system, leading to the increase of its entropy. The general model for the evolvement of groundwater system goes asrnsuch: natural structure-evolving structure- degenerative structure.
