A comprehensive analysis was made based on the relevant information from the results of the orientation study by the Dagangshan Forest Ecosystem Research Station obtained in the past 20 years The conclusions reached from the study are as follows: The biodiversity in the area is constantly on the decline and the categories of forest, forest age and tree species were out of balance. The stumpage had reduced by 18.1% from 77.4 m3/ha to 63.4 m3/ha in this period. The ecological benefits declined and the commodity ratio of timber was low. The paper puts forward an optimized pattern of “Integration of Three Benefits with Priority to the Ecological Benefits” to carry out a rational structural adjustment. It is shown that the integration of benefits after the adoption of the optimized pattern will be increase 260 million RMB yuan or 28.1% than before. The ecosystem will be improved dramatically both in its healthiness and stability.
