Abstract: Influenced by high-strength agricultural exploitation, climate and so on, the system of groundwater resources has more and more taken on characteristics of complex system in Sanjiang Plain. Therefore, taking Jiansanjiang branch bureau as example, the approximate entropy is adopted to analyze the complexity of groundwater depth series in seven production teams of Jiansanjiang branch bureau. The results show the complexity order from big to small as follows:4th production team of Farm Qianjin, 69th production team of Farm Qixing, 22th production team of Farm Qianjin, 1th production team of Farm 859, 26th production team of Farm 859, 11th production team of Farm Qianjin, 21th production team of Farm 859. We can see that the groundwater exploitation is the key factor influencing groundwater dynamic variation. The research achievements reveal the essence of complex dynamic system, provide decision basis for scientifically managing groundwater resources in Jiansanjiang branch bureau so much as the entire Sanjiang Plain.

Key words: approximate entropy, Sanjiang Plain, groundwater depth, complexity, Jiansanjiang branch bureau
