本文分析了白藤、单叶省藤和红藤人工林的投入与产出。利用经济效益动态评价方法,采用净现值、净现值率、内部收益率三个动态指标及收益成本比、投资回收期两个静态指标进行藤林的经济效益评价。分析结果表明:在25年的经营期内,三种藤林的净现值及内部收益率分别达到3 494.63、4 657.72、16 785.12元/ha和25.95％、21.20％、28.71％;收益成本比和投资回收期分别为1.71、2.13、4.77和5.5、10.3、10.2年。经济效益高低依次为:红藤林>单叶省藤林>白藤林。经营这三种藤林在财务上不仅是可行的,而且还具有较强的抗风险能力。
This paper analyzes the input and output of the cane, monocotyledon and red cedar plantations. The dynamic evaluation of economic benefits was used to evaluate the economic benefits of Tofu by using three dynamic indicators: net present value (NPV), net present value (NPV) and internal rate of return (IRR) and cost-benefit ratio (ROI) and two static indicators of payback period. The analysis results show that the net present value and internal rate of return of the three kinds of vineyards are respectively 3 494.63, 4 657.72, 16 785.12 yuan / ha and 25.95%, 21.20% and 28.71% in the 25-year operating period. The cost-benefit ratio The payback period is 1.71, 2.13, 4.77 and 5.5, 10.3, 10.2, respectively. The order of economic benefit is as follows: red vine> single leaf provincial vine> white vine forest. It is not only financially viable to operate these three types of forest, but also have strong anti-risk ability.
