摘要：以普洱市森林资源调查规划数据为基础,采用空间自相关和空间异质性分析方法,对普洱市特有优势树种思茅松林地上生物量进行空间效应分析.结果显示,思茅松林地上生物量从西向东先增大后减小,从南向北逐渐增大.全局Moran’sⅠ指数为0.436,通过1%显著性水平检验,具有极显著的空间正相关,呈现明显的聚集分布.高值聚集(HH)占百分比(29.83%)最大,主要分布在中北部地区.空间异质水平随区域尺度增加逐渐增大.研究较大尺度生物量问题时,考虑到空间效应的影响是必要的.该研究为优化调节思茅松林空间结构、提高森林生态系统服务功能提供理论支撑,丰富空间效应在林业研究中的应用,具有一定的典型性和参考价值.
Based on the forest resources survey and planning data in Pu'er City,spatial autocorrelation and spatial heterogeneity were used to analyze the spatial effect of aboveground biomass on Pinus kesiya var.langbianensis,the endemic and dominant tree in Pu'er City.The results showed that the aboveground biomass on P.kesiya var.langbianensis forest increased first and then decreased from west to east,and gradually increased from south to north.The global Moran's I index of the biomass on P.kesiya var.langbianensis forest was 0.436,which passed the 1%significance level test and showed a very significant spatial positive correlation,presenting an obvious aggregation distribution pattern.The high value aggregation(HH)of biomass accounted for the largest percentage(29.83%).It is mainly distributed in the central and northern areas of Pu'er City.The spatial heterogeneity level of biomass gradually increases with the increase of regional scale.Consequently,it is necessary to consider the influence of spatial effect when studying large-scale biomass problems.The study provided theoretical support for optimizing and adjusting the spatial structure of P.kesiya var.langbianensis forest and improving the service function of forest ecosystem,and enriching the application of spatial effect in forestry research which has certain typical and reference.
