Abstract: The analysis of material flow was applied in forest ecosystem. It provided a new way of thinking and method for determining the ecological forest logging operations reasonably. Based on the international research of material flow, we analyzed the material flow in forest ecosystem. Based on timber production technology in logging area, we drew the material flow chart of timber production. According to the plantation production characteristics, we made a fixedpoint observation method to analyze plantation production material flow and provide analyzing indicators for consulting. Plantation material flow analysis and indicators will be the subject for future followup studyusing cleaner production technology in the logging area, researching material reduction pattern of forest areas for plantation, and logging mode system life cycle assessment services.
