提出了地表MPBL系统的概念，并认为它是一个开放性的复杂巨系统；在此基础上探讨了地表MPBL系统内的三大类复合系统及其自组织问题，给出了一个较完整的地表MPBL系统结构模式，可作为认识各种时间尺度全球环境变化的研究纲领；为了适应10³～10⁵a、10¹～10²a两个尺度全球环境变化研究需要，也对这两个尺度全球环境变化模型进行了一些改进，使其更符合地表MPBL系统概念。

The author puts forward the concept of multi-phase-sboundary layers(MPBL) system and holds that that is the research object of contemporary earth system science. Accordingly, the author probes into three kinds of compound-sphere self-organization in MPBL system and gives an integrated structural model of MPBL system that can be regarded as basic guiding principles of recognizing global environmental change. To research global environmental change on two time scales(n×10³a-n×10⁵a, n×10a-n×10²a) more thoroughly, the author makes improvement to the models of global environmental change on two time scales.
