| Abstract: | Based on the systems analysis of the ecosystem in intervale region of south China, the feedback structure model of the ecosystem was established by rate variable fundamental in-tree modeling of System Dynamics.The prevailing feedback loop of the ecosystem was established according to system simulation.The result showed that major factors affecting the ecosystem were population and energy resources, the main way of containing the ecosystem deterioration was developing the forestry and fruit industry, and the ecological agriculture using biogas as link. |
