摘要: 应用地统计学的原理和方法研究了长白山岳桦种群空间分布格局及其空间相关关系,首先通过样方调查数据计算岳桦材积的半变异函数,拟合半变异函数模型,然后根据拟合的最优半变异函数模型,进行空间数据插值、绘制岳桦材积的克立格图.最后对所得到的不同海拔岳桦材积的半变异函数图和克立格图进行分析,结果表明,在海拔1650~1700m岳桦材积的半变异函数曲线为球形,其空间分布格局为聚集型,种群呈衰退趋势;在海拔1750~2000m岳桦材积的半变异函数曲线为直线形,其空间分布格局为随机型,种群较稳定;在海拔2000~2150m岳桦材积的半变异函数曲线为球形,其空间分布格局为聚集型,种群呈增长趋势.这说明长白山岳桦整体上有一种向上迁移的趋势,尤其是过渡带中的岳桦表现则更为明显.

Abstract: The distribution pattern and spatial correlation of Betula ermanii population in Changbai Mountain were studied using the theory of geostatistics. According to the data,these mivariograms of Betula ermanii volume were calaculated,the models of semivariograms were simulated, and Kriging interpolation was also done to draw the Kriging map. The results showed that at the elevation of 1650~1700m, the semivariograms of Betula ermanii volume could be described as spherical model,the spatial distribution pattern was the aggregated type,and the population was in a trend of declining.At the elevation of 1750~2000m, the semivariograms of Betula ermanii volume could be described as linear model, the spatial distribution pattern was the random type, the population was stable.At the elevation of 2000~2150m, the semivariograms of Betula ermanii volume could be described as spherical model,the spatial distribution pattern was the aggregated type,and the population was in a tend of increasing. Betula ermanii population in Changbai Moutain was in a trend of moving upper,especially Betula ermanii population in the ecotone.
