摘 要:为弥补黄山松林分货币收获表空白,以黄山松为研究对象,通过探讨林分货币收获表编制的基本原理和方法,构建了基于哑变量的地位指数模型及与立地质量有关的标准蓄积量模型。选用了L-P R M法作为林分直径分布概率预估技术,结合实测数据,建立了全林分模型和林分出材率模型,编制了黄山松标准货币收获表,对提高黄山松经营决策的科学性具有重要的实践意义。To fill up the gap, the monetary gain statement of the Pinus taiwanensis is developed through the study of the basic princi-ples and methods involved in the process. First, the standard volume model is devised based on a dummy variable index model taking into account the relevant Site Index and Site Quality and choosing the L-PRM method as the predictive control technology for the stand diam-eter distribution probability. Then, combined with the measured data, the whole stand model and the forest stand out-turn percentage model is consequently set up. Finally, it is pointed out that the development of the standard monetary gain statement of the Pinus taiwa-nensis is of great significance to its scientific management and the efficient decision-making in the matters involved.
