土地生态系统的复杂性研究

摘要/Abstract

摘要： 运用复杂科学理论,阐述了土地生态系统的复杂性特征,包括多层次性、高维性,子系统关联的复杂性,结构与功能的不确定性,开放性、动态性,自适应性和自组织性等复杂性特征,并进一步探讨了分形、混沌及人工神经网络在土地生态系统复杂性特征研究中的应用.

Abstract: In recent years,complexity studies has become a new research region and been widely applied in engineering,bio-logy,economy,management,military,police and sociology. In this paper,from the view of complex science,the main complexity characteristics of land ecosystem were described,furthermore,the application of fractal,chaos,and artificial neural network on the complexity of land ecosystem were also discussed.

Key words: Land ecosystem, Complexity, Chaos, Fractal, EM compost, community composition, biodiversity., micro- and medium-sized soil fauna, black soil, farmland ecosystem
