摘要
用动态经济评价方法对浙江省南部的庆元杉木种子园的投资结构及经济效益进行了评价。结果表明：（１）该园在２０ａ生产周期内生产性投资６１．６５万元，占种子园总投资的６６．３１％，基建、设备投资占３３．６９％。其中１５ａ产种期投资为５２．０２万元，占良种生产区总投资５７．６６万元的９０．２２％；（２）该园在２０ａ生产周期内销售种子收入达６４．４１万元，就此一项就回收了６１．６５万元的生产性投资。净现值为２９．６６万元，内部收益率达８．０％，成本效益率为１．４２元，投资回收期为１９．２５ａ；（３）该园良种子代材积的遗传增益为１５．３９％，因此宏观静态评价为，每投资种子园１元钱成本，可使良种使用者在１个轮伐期后获得１８０．７０元的额外收益。
Investment composition and economic benefit of the Chinese fir seed orchard in Qingyuan County,Zhejiang Province were analysed and evaluated.The result showed:(1)in this orchard,616.5 thousand Yuan of fund for production was invested in 20. years productive periods,that accounted for 66.31% of the total invested in the orchard.And the investments in capital construction and equipment were 33.69% of the total.520.2 thousand Yuan was invested in seeding periods of the later 15 years,that amounted to 90.22% of the total invested in superior seed producing area.(2)incomes of selling seeds totaled up to 644.1 thousand Yuan in 20 years of productive periods,that retrieved a fund of 616.5 thousand Yuan.The NPV was 296.6 thousand Yuan, IRR was 8.0%,and the BCR 1.42 Yuan.Through a period of 19 years and 3 months,the investments have been retrieved.(3)the volume genetic gain of good strains was 15.39%,so the good strain user would get 180.7 Yuan else by investing one Yuan after one lumbering rotation.Based on systematic methods,it showed a good social and economic benefit in this seed orchard.
