宁化国有林场树种结构调整方案探讨

Discussion on Structural Adjustment Program of Forest Species of Ninghua State-owned Forest Farm

以现有人工纯林地力普遍衰退,林分总体质量下降为背景,从分析宁化国有林场森林资源现状入手,分析总结较优的混交造林模式和选择适宜造林树种,以优化造林模式,增加阔叶树造林面积,利用阔叶树在林地养护、地力保持、维持生态系统平衡等诸多方面的作用,从而达到调整和优化宁化国有林场树种结构的目的。

Taking the recession of land capability in general of existing artificial pure forests,the decline in the overall stand quality as the background,started from the analysis of status quo of forest resources in state-owned forest farm,better models of mixed reforestation and suitable tree species selection were analyzed and summarized,in order to optimize the reforestation mode and increase reforestation area of broad-leaved trees.The role of broad-leaved trees in forest land maintenance, soil capability conservation, maintenance of ecosystem balance and many other aspects were used to achieve the purposes of adjustment and optimization of tree species structure in Ninghua State-owned Forest Farm.
