采用静态经济指标分析了富阳和临海的新无性系短轮伐期工业用材林的经济效益,结果表明:短轮伐 期工业用材林的营林成本主要由种苗、肥料和劳务三部分费用构成,三者的比例在不同地区、不同营林时间 差异极大;现实林分营林成本的79.8%~92.3%都发生在造林当年,资金的投入相对比较集中;临海点5年生 林分产值为 12 015.00~29 808.00元/hm2,富阳纸浆林 6年生时产值为 16 411.50~24 795.00元/hm2。产出投入 比高达3.78~6.71和4.13~4.80:无性系是影响经济效益的最主要因素之一,临海点366无性系产值是69对 照无性系(3×3密度时)的1.99倍;各种造林密度下平均利润366的是69的2.19倍,造林密度是另一影响经济 效益的主要因素。
The economic benefits of the short clinker industrial timber plantations of Fuyang and Linhai using static economic indicators were analyzed. The results showed that the cost of silviculture of short-rotation industrial timber plantations consisted of three parts costs of seedlings, fertilizer and labor, and three The proportions of farmers in different regions varied greatly. The actual cost of silviculture was 79.8% ~ 92.3% of that in afforestation, and the investment of funds was relatively concentrated. The 5-year-old forest Output value of 12 015.00 ~ 29 808.00 yuan / hm2, Fuyang Pulpwood 6-year-old production value of 16 411.50 ~ 24 795.00 yuan / hm2. The ratio of output to output was as high as 3.78 ~ 6.71 and 4.13 ~ 4.80. Clone was one of the most important factors affecting economic efficiency. The output value of 366 clone near sea point was 69 control clones (3 × 3 density 1.99 times; the average profit 366 of various afforestation density is 2.19 times 69, afforestation density is another major factor affecting economic efficiency.
