昆嵛山腮扁叶蜂幼虫空间自相关研究

运用全局Moran’s Ⅰ和局部Moran’s Ⅰ方法对昆嵛山腮扁叶蜂幼虫空间分布的自相关性进行了研究。结果表明：昆嵛山腮扁叶蜂幼虫在样地的分布具有一定的空间自相关性，但未达到显著的程度，没有形成特定的空间分布格局；局部空间自相关分析结果显示也没有局部空间聚集现象。由于样地环境比较单一，因此只考虑昆嵛山腮扁叶蜂易感林木的空间自相关对昆嵛山腮扁叶蜂空间自相关的影响。用相关性分析昆嵛山腮扁叶蜂全局Moran’s Ⅰ值和易感林木全局Moran’s Ⅰ值的相关性可知，昆嵛山腮扁叶蜂全局空间自相关性受易感林木全局空间自相关性显著影响。

Study on larval spatial autocorrelation of Cephalcia kunyushanica Xiao

The article is to study autocorrelation of spatial distribution of Cephalcia kunyushanica Xiao by using the method of global Moran's I and Local Moran's I analysis. Results showed that distribution of C. kunyushanica Xiao had the spatial autocorrelation at a certain degree but don't take on the significant positive correlation so don't have a specific distribution pattern. Meanwhile, significant local spatial autocorrelation of C. kunyushanica Xiao don't also occurred. We only consider that spatial autocorrelation of C. kunyushanica Xiao is influenced by spatial autocorrelation of C. kunyushanica Xiao's susceptible trees or not as environment is very simplex in specimen field. To study relationship between index of global Moran 's I of C. kunyushanica Xiao and index of susceptible trees's by using method of correlate analysis. The result show that autocorrelation of spatial distribution of C. kunyushanica Xiao is evidently effected by spatial autocorrelation of C. kunyushanica Xiao's susceptible trees. Spatial autocorrelation analysis can be used to research spatial autocorrelation of C. kunyushanica Xiao, and it is a good way to find out the spatial distribution at different stages.
