摘要:
 以西藏色季拉山暗针叶林1 hm2的固定样地调查资料为基础,运用点格局分析方法中的Ripley’L函数讨论了西藏色季拉山白桦、糙皮桦、川滇高山栎、急尖长苞冷杉与林芝云杉5个主要种群空间分布格局及其种间关联性。结果表明:西藏色季拉山暗针叶林5个主要植物种群与种间关联对空间尺度均具有较为强烈的依赖性,并且该区域5个主要植物种群的聚集强度和种间的相关性随着空间尺度的增大呈现出交替或者摆动现象;5种群空间分布格局总体表现为:林芝云杉、白桦和糙皮桦在较小尺度和较大尺度范围内主要呈随机分布,在小尺度和中尺度下主要呈集群分布,并且林芝云杉和糙皮桦在中尺度的聚集强度要明显强于白桦。而急尖长苞冷杉和川滇高山栎随着空间尺度的增大,种群分布格局基本上呈集群分布;5个主要种群的空间关联分析总体表现为:以负关联和无关联为主,只有白桦和糙皮桦在43~44 m尺度下表现为正关联。白桦与糙皮桦、川滇高山栎、林芝云杉、急尖长苞冷杉,川滇高山栎与糙皮桦、急尖长苞冷杉、林芝云杉在中尺度下均呈明显负关联,其他尺度下无明显关联性;糙皮桦与林芝云杉、急尖长苞冷杉在任何尺度下均无明显关联性。说明西藏色季拉山暗针叶林主要植物种群间竞争非常激烈,群落结构不稳定。
Abstract:
 Based on the data collected from 1 hm2 stationary sample plot of dark coniferous forest of Sejila Mountains,Tibet,China,spatial distribution patterns of the five major plant populations (Betula platyphylla,B.utilis,Quercus aquifolioide,Abies georgei var.smithii,Picea likiangensis var.linzhiensis) and their interspecific relationships were discussed using Ripley’L function in point pattern analysis.The results showed:five main plant populations of dark coniferous forest and their interspecific relationships had a relatively strong dependence on spatial scale.With the increase of spatial scale,the congregation intensity and interspecific association of this five main plant populations basically showed the phenomenon of alternation and swing.The interspecific association of five populations also had a strong dependence on spatial scale.The spatial distribution patterns of P.likiangensis var.linzhiensis,B.platyphylla,B.utilis mainly were random in the ranges of relatively small scale and large scale,while distributed mainly in cluster in the range of small and middle scale.The congregation intensities of P.likiangensis var.linzhiensis and B.utilis were stronger than that of B.platyphylla in middle scale.While with the increase of spatial scale,the population distribution patterns of A.georgei var.smithii and Q.aquifolioides were distributed basically in cluster.Negative intra-specific and no intra-specific relationships were mostly found among five populations,only B.platyphylla and B.utilis presented positive intra-specific relationships in the scale range of 43-44 m.When in the range of middle scale,negative intra-specific relations dominated between B.platyphylla and other four species,as well as between Q.aquifolioides and B.utilis,A.georgei var.smithii,P.likiangensis var.linzhiensis,while in the other scale ranges,there were no obvious relationships.At any scale ranges,there were no obvious relationships between B.utilis and A.georgei var.smithii,P.likiangensis var.linzhiensis.It indicated that there were intense competitions between main plant species,resulting in unstable community structure.
