Abstract: 

Groundwater possesses resources function, ecology function and geological environment function. The eco-environmental and geological problems caused by the unreasonable abstraction of groundwater can all be attributed to the degeneration and loss of groundwater function. The evaluation of groundwater function is the foundation of groundwater management. Groundwater system is dissipative structure system. On the basis of order degree and entropy of dissipative structure system, this paper establish a set of new and more adaptive evaluation index system and evaluation model of groundwater function, which are applied in the evaluation of groundwater function in Tianjin. The results indicate that the region with moderately strong groundwater comprehensive function mainly locates in Ji County. While groundwater comprehensive function in Baodi District and Wuqing District is moderate, and other regions are moderately weak or weak. These findings may help decision-makers for devising sustainable groundwater management strategies in Tianjin.
