摘要
为探寻甘肃省子午岭林区油松人工林适宜的经营模式,以30年生油松人工林为试验对象,分别设置目标树全林分经营、传统分级法经营、目标树近自然经营3种经营模式,比较不同经营模式下人工油松林林分生长及经济收益情况。结果表明,不同经营模式对人工油松林树高、胸径、蓄积、出材量存在显著影响,经济收益也存在较大差异,综合考虑,认为目标树全林分经营模式油松生长状况良好、经济收益较高,是适宜甘肃省子午岭林区的油松林经营模式。
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.
