Abstract
Lienhuachih fir plantation experiments stand age more than 30 years, permanent plot observations of the past 14 years, found that the performance of Chinese fir plantation grown gradually deteriorates, DBH growth arrest, about 15-20cm among and accumulation per unit area decreased rather than increased, especially over 35 years old of afforestation, the volume per hectare dissatisfaction 100m3. Lienhuachih Experimental Forest Garden overstating between 500-1000m, the area of agriculture, forestry, mixed mode operation is very common. Therefore, this project intends to select Lienhuachih test forest fir forest degradation, the level of implementation of the ranks and the block logging finishing banded conducted coppice, discuss the implementation of "forest economy" dog bone Aberdeen planting practices, camellia, etc., while with FSC certification performed to enhance product quality and value, increase farmers' income, while at the same both ecological environment, the benefits of carbon sequestration.
