| 摘 要： | 经济效益综合评价是产业决策研究的重要内容.从系统工程观点来看,经济效益综合评价本质上是一个有限方案多目标决策问题.因此,本文采用多目标决策法对杨树速生丰产林的主伐决策进行研究,以年均净现值、内部收益率、土地期望价、效益成本比、成本利润率为指标,提出用熵技术法确定评价指标权重,结合"理想点"法、TOPSIS法和线性加权和法三种方法对决策方案进行排序择优,得到不同排序结果,最后用平均值法得到最终综合评价结果.结果表明,对所研究的密度为10×10m~2、8×8m~2、6×8m~2、5×6m~2的杨速生丰产林进行分析得到综合评价结果,其最优主伐龄分别为:13年、10年、9年、9年.随着密度的增大,经济成熟龄提前.本研究表明该方法对杨树速生丰产林的主伐决策研究是有效可行的.

| Abstract: | The economic benefit evaluation is one of the important contents of the industrial decision.From the angles of systems engineering,essentially,the economic benefit evaluation is a multi-objective decision-making problem.The paper studies clear cutting decision of poplar fast-growing and high-yield plantation for multiple objectives.Using annual mean net present value, internal rate of return,land expected value,benefit cost ratio and profit cost rate as evaluation indices,applied entropy technique method to... |
