Co-evolutionary study on the ecological environment and the social economy multiplexed system

Through the system analysis of water resources restraint, the ecological environment and the social economy multiplexed system's competition and cooperation, this article uses the synergetics theory as a foundation to establish the multiplexed system's degree of order models and the multiplexed system's coordination evolution model, which produces the corresponding computational method. The paper analyzes the model correspondingly and points out that the multiplexed system's coordination evolution is divided into three kinds of situations in the different states: the part competition substitution, the part competition coexistence and the completely independent coexistence. Finally, based on the General Bureau of Heilongjiang State Farm's ecological environment and the social economy multiplexed system's statistical data from 1986 to 2006, the paper establishes the corresponding coordination evolution model and carries on the analytic computation, the result is basically consistent with the reality.
