摘要: 基于天山中部云杉生长分布的生境条件,综合考虑水、热、地形因素,利用3S技术和空间建模技术构建云杉分布生境指数模型,通过选取生境指数阈值,预测了天山云杉林潜在分布区.结果表明: 模型模拟的潜在分布区与现有云杉林分布区生境条件差异不显著,而与云杉林不可分布区生境差异显著;基于构建的生境指数模型,界定出研究区有7.01×103 hm2的林地下限带、林间空地及阴坡半阴坡区域为云杉潜在分布区,占研究区总面积的6.4%,是未来林地的发展空间.

Abstract: This paper predicted the potential distribution area of the spruce forest on the central Tianshan Mountain, through determining the site index thresholds, using 3S and spatial modeling technologies to build a site index model with water, heat, terrain and other factors, based on the current site conditions there. The results showed that the potential distribution area simulated by the site index model was not significantly different with the current actual distribution area, but had a significant difference with the non-spruce forest area. Based on the built site index model, there was a large potential distribution area, which occupied 6.4% of the total research area, i.e., 7.01×103 hm2 of forest lower boundary zones, glades, shady and half shady slope areas, and could be used for the future forest development.
