摘要: 对3种不同经营方式下杨梅Myrica rubra的混交度和角尺度进行了比较研究，采用胸径、生物量、冠幅和树高计测大小比数对不同经营方式下杨梅林分空间结构进行分析。研究结果表明，集约型杨梅林分的混交度为0，复合型的平均混交度大于粗放型的平均混交度；各样地的角尺度平均值为0.564 ～ 0.667，均属于集聚分布格局，但复合型的角尺度分布图基本上呈正态分布，所以复合型杨梅更接近于均匀分布；复合型经营方式下，杨梅林分的胸径大小比数、生物量大小比数、冠幅大小比数和树高大小比数较其他2种经营方式下分布均匀。复合型经营更有利于生态效益的发挥。在森林经营管理中，以杨梅为目的树种进行林分配置时，以树高优势较杨梅弱的下层树种为宜；择伐时应尽量保留大小比数比最近邻木高的个体。图6表2参13

Abstract: We compared Myrica rubra forest under three different managements using the analysis of forest spatial structure in Xianju County，Zhejiang Province，where the M. rubra is one of the majority economic tree species. The objective of the study was to provide a quantitative description of the spatial structure of the three plots （plot 1 named X1 is intension type；plot 2 named X2 is extensive type and plot 3 named X3 is compound type.），and to present a method for comparative analysis of the three forest sites. The results showed that，the mingling degree of the M. rubra on X1，X2 and X3 were 0，0.208 and 0.336 respectively. The average neighborhood comparison of each plot range from 0.564 to 0.667 all were belong to cluster distribution pattern，but the average neighborhood comparison of the compound forest was closer to normal distribution. Therefore compound M. rubra forest is closer to uniform distribution than other two types. The neighborhood comparison measured by diameter at breast height（DBH），biomass，canopy breadth，and tree height under compound type had a slighter fluctuation range than the other two. Compound type is the most beneficial way of the three managements to maximize the ecological benefits. It was possible that increasing individual’s DBH to enhance its biomass，and thus，to achieve its predominance status among individual’s competition was the main strategy of individual’s differentiation. Neighborhood comparison should also be taken as an instructive reference in modifying the spatial structure of stand.［Ch，6 fig. 2 tab. 13 ref.］
