Abstract
World population growth is charged with the most fundamental driving force of global environmental deterioration. Usually, demographic factors are considered as externals of environmental systems, and treated as given conditions. Their impacts and sensitivity on environment as well as the mechanism of demographic evolution may closely linked with environmental change, however, quantitative study on the relation and their separability has been seldom conducted. In our study, a cohort-component model was developed in order to connect and interfacing the global demographic and environmental trends. Coupling with the model with comprehensive global environmental model which we have developed already, the implication of global population growth and its spatial distribution were quatitatively analyzed.
