Complexity of Groundwater dynamic in Jiansanjiang based on Fractal Theory

摘要

The complexity of Groundwater dynamic was determined based on the fractal dimensions of groundwater depth sequence of all farms in Jiansanjiang calculated in Grassberger-Procaccia algorithm. It is showed that groundwater dynamic in Jiansanjiang is of certain complexity for fractal dimensions of all wells greater than 1. The complexity of groundwater in Jiansanjiang has a significant spatial variance structure characterized with the complexity of groundwater dynamic in the northwest lower than that in southeast, which indicates that the groundwater system in the southeast fluctuates more strongly and affected by natural and human disturbances more seriously.
