摘要: 以新疆天山西部云杉林为研究对象,采用Moran I指数进行量化分析,将林相图与DEM叠加后,对所得的量化结果进行分析。研究表明:云杉林基本分布在高程为1 400~2 700m的高度,其中在15~45°坡度范围内分布有77.69%的云杉林,在北、东北、西、西北的坡向上有74.75%的云杉林分布。从地形因子的角度分析,云杉林空间分布呈现明显的规律性。

Abstract: Based on DEM, this study analyses spatial differentiation of vegetation with Picea schrenkiana in Gongliu Tree Farm in Xinjiang as an example. To detect data used in the research which is subject to normal distribution characteristics, the authors illustrate the Normal QQ Plot in ArcGIS9.0 platform. With Moran I index, the authors figure out that distribution of Picea schrenkiana is spatial auto-correlation. Analysis of directional distribution shows Picea schrenkiana runs from northeast to southwest imposed mainly by terrain factors. The overlaying result shows that Picea schrenkiana is mainly distributed at the elevation of 1400~2700 meters. And 77.69% of trees of Picea schrenkiana is distributed on the slope between 15 °~45 °and aspects of north, northeast, west and northwest. It concludes that the relationship between factors of terrain and spatial distribution of Picea schrenkiana is apparently regular.

Key words: DEM, spatial auto-correlation, terrain differentiation, spatial distribution, Picea schrenkiana in the west of Tianshan Mt
