摘要: 为研究高黎贡山南段森林景观变化与驱动力之间的相互关系,在GIS 支持下对高黎贡山1974、1987、1997、2006 年4 个时期遥感影像森林景观分类数据,利用成本距离分析方法对村庄居民地和道路对森林景观变化的关系进行研究,并分析成本距离和景观空间变化关系。结果表明:高黎贡山森林变化呈先增加后减少的趋势;森林变化在海拔1000 ~2000 m最为活跃。森林变化与村庄居民地和道路的距离具有较高的相关性,通过数学拟合达到较高显著性。

Abstract: In order to study the relationship between the forest landscape change of Gaoligong Mountain and its driving force, remote sensing satellite images of 1974, 1987, 1997 and 2006 in Gaoligong Mountain were obtained and interpreted. The cost-distance analysis was used to study the effect of villages and roads on forest landscape change, and function fitting was carried out to explore the relationship between cost-distance and landscape spatial change. The results indicated that the variation of forest in Gaoligong Mountain showed a trend of first increase and then decrease, the changes of forest were obvious in the elevation of 1000-2000 m. There was a significant correlation between forest changes and villages and roads, mathematical fitting showed high significance.
