SOME PROBLEMS IN THE STUDY ON HUMAN-LAND SYSTEM WITH THE METHODS OF SYSTEMATIC DYNAMICS

人地系统动力学研究是当前地理学研究的最主要领域，应从人的生存和发展需要出发，围绕人类活动的环境效应和人地协调发展主线选择研究对象，界定研究内容，采用物质能量守恒分析和统计分析相结合的方法，加强对人地相互作用机制的研究。

The study on human-land system with the methods of systematic dynamics is the main fieldof geography. It is considered that human should be liken as the stUdy center and the interactionbetween man and land as the main study clue. In construction if human- land system, thesystematic elements should be selected according to environment in which human take up theactivities of production and life. In determination of study content, the action of man upon landshould be taken as the focal POint and the actional model and intensity should be studiedsynthetically and dynamically. As for the study methodology, it is thought that more experimentaland simulated methods should be adopted, such as those of conservation of matter and energy,statistical inference and so on, and quantitative analysis on interactional machanism and intensityshould be made. In the paper, a detailed discussion is conducted un selecting study concent anddetermining study focal point in the east coastal area of China.
