- 摘要:
- 杉落混交林是河北省木兰林管局的一个重要林分类型,为提高该地区林木经济效益,采用野外调查杉落混交林不同树种的分布密度、断面积、胸径、苗高等数据,评估杉落混交林绿化大苗经济价值、木材经济价值和总价值。结果表明:杉落混交林绿化大苗经济价值为69.375 25万元?hm-2,木材经济价值为14.347 6万元?hm-2,总经济价值为83.722 85万元?hm-2。由此看出杉落混交林绿化大苗经济价值高于木材经济价值,落叶松和云杉经济价值高,可以通过近自然经营,使杉落混交林针阔比达到7∶3,提高云杉和落叶松的整体比重,最终使杉落混交林经济效益最大化。
- Abstract:
- Theropencedrymion is an important forest type of Mulan forestry administration in Hebei province,in order to improve the overall economic benefits of forest in the area through the preliminary assessment by falling economic value to the mixed forest,the distribution density,sectional area,DBH and height equivalent of different species were surveyed,green seedlings in economic value,economic value of timber and total value were evaluated.The economic value of greening seedlings of theropencedrymion was 693.752 5 thousand yuan ?hm-2,economic value of timber was 143.476 thousand yuan?hm-2,the total economic value was 837.228 5 thousand yuan?hm-2.The results showed that the economic value of mixed forest green seedlings was higher than that of timber,larch and spruce with high economic value,which could be operated through the natural,the ratio of mixed forest for fir with falls reached 7∶3,and improved the overall proportion of spruce and larch,eventually made maximum economic benefits for mixed forest.
