%X Regional "nature-society-economy" complex system is an exoteric gigantic system with dissipation structure and high-step, multi-variables, multi-loops and nonlinear feedback structure, the action of the system sometimes have anti-vertical and a think skin to the changes of interior parameter. Applying system dynamics method to establish models of regional sustainable development can depict systemic nonlinear structure and dynamic character more adequately than traditional mathematic models. With a view to the complex dynamic relation of regional sustainable development system, taking county region for an example, three projects were simulated: (1) Economy accrual method. The intensity of resource exploitation and environment pollution is the least, but the speed of its economy development is the lowest. (2) Economy high-speed development method. The intensity of resource exploitation and environment pollution is the worst, economic development mostly depends on high investment and pollution. (3) Economy moderation development mode. The mode considers not only economic sustainable development and natural recourses utilizing reasonably, but also gives attention to pollution protection and development of industry, agriculture, tourism and so on. So it is the best mode.
