本文一反传统的静态分析方法，介绍了林业项目经济效益评价的动态方法。并对江苏省宝应湖农场池杉林的经济效益进行了预测和分析，结果表明，在达到主伐年龄时，每公顷的财务净现值（确定收益率为１２％）为５０８２９．９６元，远远大于造林投资。财务内部收益率为２２．７％，是社会基准收益率的１．８９倍，获利能力很强。敏感性分析表明，当木材产量、木材价格分别降低１０％，经营成本提高１０％的情况下，其内部收益率仍高达２１％，远大于社会基准收益率，说明项目经营风险很小．
In this paper, an anti-traditional static analysis method, introduces the dynamic method of economic evaluation of forestry projects. And the economic benefits of taxodium ascendens forest in Baoying Lake Farm in Jiangsu Province were predicted and analyzed. The results showed that the net present value of finance (determined yield of 12%) was 50,829.96 yuan per hectare at the age of main cutting, Invest in afforestation. Financial internal rate of return of 22.7%, 1.89 times the social benchmark return rate, strong profitability. Sensitivity analysis shows that the internal rate of return is still as high as 21% when the timber output and wood price decrease by 10% and the operating cost increase by 10% respectively, much higher than the social benchmark rate of return, indicating that the project management risk is very small.
