摘　　要：针对目前土地科学研究中部门间相互封闭、理论与实践脱节的不可持续现状,根据土地科学研究自身特点,构建了土地科学研究的三部门框架,解析了土地科学可持续发展的因果关系,运用系统动力学理论进行系统分析与构建,构造出系统动力学模型。通过本文研究得出,土地科学研究可持续发展系统的动力源自实践中的问题与矛盾,传输渠道畅通是系统持续运行最重要的决策点,模型由此实现土地科学领域的理论与实践研究的统一,通过系统的循环运作,促使土地科学研究过程产生可持续运行机制,系统可持续发展功能臻于完善,有效地解决现行土地科学研究中的不可持续现状。Nowdays,departments are mutually close to each other, and theory divorces from practice in land science research. According to the present unsustainable situation and the characteristics of land science research, this paper constructs the three-department framework on land science research. Applying system dynamics theory, we analyse the causal relationship on sustainable development of land science and construct the system dynamics model. The power source of system is the problems and contradictions in practice, smooth transmission channel is the most important decision point. By this way, the model achieves the unification of theory and practice in land science research field. Through the cycle operation of system, sustainable operation mechanism can be produced, the sustainable development function gradually improved,and the existing unsustainable situation in land science research effectively solved.
