摘要
随着21世纪环境问题范围的扩大和严重性的恶化,人们需要建立集成模型分析、描绘自然和人类系统之间复杂的过程,辨析人文因素的作用.对于人文因素作用的集成评价和模拟,既有全球尺度的模型,还包括环境问题的局地和区域模型.回顾和评述了国际上的一些常用集成模拟模型,在分析这些模型优缺点的基础上,总结了未来集成研究方法的主要特点.模块化、分等级的模型结构可以简化集成模型的建立过程,自然和社会过程的耦合是集成研究的焦点内容.
The natural factors are often defined according to spatial-temporal scale,while the human factors are often defined according to analytical scale. In order to identify the function of human factors,a unified framework is needed to integrate the nature and human factors. In addition,the environment problems,which are caused by the interactions of natural and human systems,are very complicated. Only the development and application of integration tools can researchers better analyze and describe the ongoing process. In this paper,first some models are introduced,which are often used to analyze the function of human factors. After comparing the advantage and disadvantage of these models,some main characteristics of the integrated research method are summarized.
