湿地松 Pinus elliottii 是我国南方地区重要的人工造林树种。与采脂林和用材林相比,脂材兼
用的经营模式有利于增加单位面积经济收益。为了评估广东湿地松脂材兼用林的经济效益及其影响因素,
研究通过问卷调查形式,收集广东 6 块湿地松林分经济投入与产出数据,对经济效益作比较分析。结果
表明,脂材林的现金支出主要集中在采伐成本,占总支出的 74.30%~93.72%;现有的经营模式可以取得
可观的经济效益,贴现率取 8% 时,净现值在 1.46 万 ~3.40 万元之间,内部收益率在 11.95%~30.61% 之
间;湿地松脂材林净现值受松脂价格影响最为敏感,次之为松脂产量和脂材采收成本,培育成本是相对
最不敏感的因素。综上分析认为,在脂材林经营过程中,种植户可通过选购优质种苗、采用合理的集约
化培育措施的方式提高松脂产量,从而提高收益;在政府层面,一方面可建立松脂价格支持机制、培训
农户规范采脂,以实现松树林的可持续开发;另一方面,可加大脂材采收技术与装备的研发投入,提高
我国采脂、伐木的效率,降低作业成本。 |

Abstract: |
Pinus elliottii is an important afforestation tree species in the south of China. Compared with the
plantations used only for resin or timber, the management mode of plantations used both for resin and timber (PURT)
is bene?cial to increase the economic bene?t per unit area. In order to evaluate the economic bene?ts and the related
in?uencing factors of PURT in Guangdong, the data of the input and output of 6 P. elliottii stands were collected
through a questionnaire survey and compared for the economic benefits. The results show that the cash outflow
of PURT was dominated by harvesting cost, which accounts for 74.30%-93.72% of the total cost. The current
management modes could achieve considerable economic bene?ts. The net present value (NPV) was 14 600 CNY
to 34 000 CNY, and the internal rate of return was 11.95% to 30.61% when the discount rate was 8%. The NPV ofP. elliottii PURT was most sensitive to the resin price, followed by the resin yield and the harvesting cost for resin
and timber, while the silvicultural cost was relatively least sensitive. Based on the above analysis, it is believed that
the growers could increase the resin yield by purchasing high-quality seedlings and adopting intensive cultivation
measures when managing the PURT, thereby increasing the economic bene?ts. To achieve sustainable development
of pine plantations, it’s suggested that the government could establish the price supporting mechanism, and train
the farmers for standardizing resin tapping. Meanwhile, it’s also suggested that the government could increase the
investment in research and development of resin harvesting technology and equipment, which will increase the
ef?ciency of harvesting resin and timber, and decrease the operating costs as well. |
