In this paper, Subalpine conifer forest ecological system was brief introduced, and their non-equilibrium problems were discussed at the level of population, community and ecological system.

In the article,the features on opening and non-equilibrium of the information-system of university were researched,the role of fluctuation for self-organization evolution of the system was revealed,the process and direction of self-organization evolution of the system were approached with reality on the basis of the self-organization theory.

This paper systematically analyzes the openness,non-equilibrium,non-linear,the process of self-organizing and nonlinear dynamics of agroecosystem,to provide theoretical basis for the regulation and control of agroecosystem,as agroecosystem is of dissipation structure.

The phenomenon of time and space being highly ordered in biological system is of great use to explain the theory of nonequilibritory nonlineraity in chemistry.

The simulation results showed that the imbalance of data due to missing observations led to lower precision and lower exactness of variance component estimation,to underestimation of the error of fixed effects as well as to higher type Ⅰ error rate for fixed effect test.
