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。
Taking Picea schrenkiana forest in western Tianshan of Xinjiang as the research object, the Moran I index was used for quantitative analysis. After the forest pattern was superimposed with the DEM, the quantitative results were analyzed. The results showed that the spruce forest was basically distributed at altitudes of 1 400-2 700 m, of which 77.69% of the spruce forest distributed in the slope of 15-45 ° and 74.75 in the north, northeast, west and northwest slopes % Of spruce forest distribution. From the perspective of topographic factors, the spatial distribution of spruce showed obvious regularity.
