摘要
掌握华山松林的空间分布特征并提供定量化研究方法,能够为有效保护、恢复和合理利用华山松森林资源提供理论依据。研究基于云南省第九次森林资源连续清查样地数据分析华山松林的空间分布特征。结果表明:1)华山松林在滇西北地区各测树因子均高于其他地区,在该地区的生长较优,其次为滇东北地区;滇东北地区的郁闭度最大,但平均林龄仅为25a,反映其林分密度对环境因子的利用程度相对较好;2)华山松林平均胸径、平均高在各海拔区间波动较大,郁闭度、单位面积蓄积量在高海拔地区较大,方差也较大。
Mastering the spatial distribution characteristics of Pinus armandii forest and providing quantitative research methods can provide a theoretical basis for effective protection,restoration and rational use of Pinus armandii forest resources.The research is based on based on data from the Continuous Forest Inventory(CFI) in Yunnan province.Quantitative analysis of the spatial distribution characteristics of Pinus armandii forest using quantitative theory and methods shows that:1) Pinus armandii forest in the northwest of Yunnan province has higher tree surveying factors than other regions,the area has better growth,followed by the northeastern Yunnan;the northeastern Yunnan has the highest canopy density,but the average forest age is only 25 years,reflecting the relatively good utilization of the environmental factors by the stand density;2) the average of the Pinus armandii forest The DBH,average height fluctuations in each altitude range,canopy density,per unit area volume in the high altitude area is larger,the variance is also larger.
