摘要
人地系统的优化与调控是持续发展理论研究的重大课题，具有深远的现实意义。人地系统是由人类的社会经济活动系统与资源环境系统之间通过复杂的交互与因果作用结合而成的巨系统，每一次动态变化都伴随着大量的物质、能量和信息的传递和交换，并可看作为一个不稳定的、非线性、远离平衡状态的耗散结构。对于该系统的研究，只有从系统整体的角度运用系统科学的理论和方法，从系统发展演化的机理入手，才能为优化调控提供理论依据。本文首先从人地关系的认识过程和演替阶段入手，进而分析了人地系统的特点、结构和功能，在此基础上探讨了人地关系优化的核心与理论模式。
Abstract The optimization of man earth system lies in the way to harmonize their internal relations and to approach the goal of rational allocation among population,material,energy and informatin flow in PRED process. This paper take the man earth system as the theoretical basis. At first,the author generalizes the work beginning with the evolution period of man earth relationship in history. Secondly, analyses the main characteristics,structure,function of man earth relationship. Thirdly,points out the core of optimization and theoretical model on man earth system.
