本文采用格局分析、相关分析的方法,结合样地立木定位图研究了不同年龄结构类型的兴安落叶松种群的空间格局。结果表明,该种群具有明显的聚集分布特点。在格局分析图上,中年世代有2-3个均方峰,峰值多位于区组大小为8m ̄2和32m ̄2处;成年世代仅具一个均方峰,峰值多位于区组大小为16m ̄2和32m ̄2处;老年世代均方峰不明显或仅在区组大小为128m ̄2处有一个均方峰。不同世代在空间上也呈现明显的镶嵌特点。这种聚集、镶嵌特点在很大程度上取决于干扰状况。
In this paper, the spatial pattern of Larix gmelinii population of different age structures was studied by the method of pattern analysis and correlation analysis combined with the location map of standing wood. The results show that the population has obvious aggregation and distribution characteristics. In the pattern analysis diagram, there are 2-3 mean square peaks in the middle-aged generation, and the peaks are mostly located in the block size of 8m ~ 2 and 32m ~ 2; the adult generation has only one mean square peak, the peak more in the block size 16m ~ 2 and 32m ~ 2; the older generations are not obvious square peaks or only block size 128m ~ 2 at a mean square peak. Different generations also show obvious mosaic features in space. This kind of agglomeration, mosaic features depends very much on the interference situation.
