摘　　要：在对红壤丘陵区生态系统进行系统分析的基础上,利用系统动力学的流率基本入树建模法,建立了红壤丘陵区生态系统的反馈结构模型。提出了系统的主导反馈环,进而对影响系统运作的核心因素进行了分析。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.
