摘要

We firstly put forward the definitions and principles of ecosystem segmentation and composition,and elaborate five kinds of characteristics of ecosystem segmentation and composition. Results show that ecosystem segmentation and composition are actually its space segmentation and composition,and time change decides change and succession of any ecosystems. Via temporal-spatial change of ecosystem and segmentation and composition,change and succession trend of ecosystem and future development are determined,which lays foundation for analyzing structure and composition of earth ecosystem.
