The Impact of Management Models on the Growth and Economic Benefits of Artificial Pinus Tabulaeformis Forests
In order to explore the suitable management mode of pinus tabuliformis plantation in the Ziwuling forest area of Gansu Province,the author conducted a field experiment in the local area,taking the 30-year-old pinus tabuliformis plantation as the experimental object,and set up three management models,namely the target tree whole stand management model,the traditional grading method and the target tree near-natural management,and compared the stand growth and income of the planted pine forest under different management modes.The results showed that different management modes had significant effects on the tree height,DBH,accumulation and yield of P.tabuliformis plantations,and there were also great differences in their income.Considering all factors,the whole-stand target tree management approach demonstrates good growth conditions and higher economic returns,making it a suitable management practice for Chinese pine plantations in the Ziwuling forest area of Gansu Province.
