尤溪县造林类型及造林树种的特征研究

The Feature of Type and Tree Species for Forestation in Youxi County

[目的]为了把握资源发展情况,调查分析2011年福建省尤溪县的造林类型及造林树种。[方法]对2011年尤溪县造林情况汇总,并进行相关统计分析。[结果]共造林面积14 589.5 hm2,其中荒山造林、采伐迹地更新占主要,面积分别占38.0%、33.9%;在小班个数上,以荒山造林、坡耕地造林、采伐迹地更新为多,分别为51.3%、19.5%、15.8%。坡耕地在2011年造林中得到了很好的开发。造林树种有46种以上,以一般用材林占多数,面积为85.5%。一般用材林以杉木、马尾松为主,面积分别为7 035、5 253 hm2,占48.2%、36.0%。油茶、阔叶树类、茶叶、竹类占有较重要的位置,比例分别占6.2%、3.7%、1.8%、1.7%。混交林面积有大的增加,面积达4 914hm2,比值占33.7%。[结论]政府在树种选择上应加强指导,做到适地适树,并加强荒山造林的管理,进而更好地发挥造林绿化的作用。

[Objective]Through examining statistics,in order to find out the resources in Youxi County 2011.[Method] The total area of forestation was 14 589.5 hm2.They were main type which afforestation and cutting blank regeneration,the ratio of the area was respectively 33.9%,38.0%.The small class number of the afforestation in barren hills,slope afforestation,deforested update which respectively was 51.3% 19.5% 15.8%.The afforestation in slope got a good development in 2011.The afforestation tree species have more than 46.The general timber forest dominated 85.5%.The areas of Chinese fir and Pinus massoniana were 7 035,5 253 hm2.The area proportion of camellia oleifera abel,broad-leaved tree,tea and bamboo were 6.2%,3.7%,1.8%,1.7%.The area of mixed forests increased greatly and the area was 4 914 hm2.[Conclusion] The government should strengthen guidance in tree species selection and afforestation management,then better to play the role of afforestation.
