摘要: 基于RS和GIS技术分析岷江上游1994年、2004年和2014年3个时期河谷聚落的时空分布,阐述其基本特征和演化规律.结果表明:河谷聚落是岷江上游最主要的聚落形态,全流域呈松散状,局部呈集聚分布;其总面积不断增大,聚落密度呈先集聚后局部衰退;平面形态整体上由规则向不规则形态变化;其斑块的分布特征为高程上整体逐渐向低海拔迁移,坡度上先向低坡度迁移后逐渐向5°~35°区迁移,全流域由1994-2004年的呈轴对称向2004-2014年间的东南、南、西南、西方向迁移.Abstract: With the support of RS and GIS technology, the spatial and temporal distribution of valley settlements have been analyzed in the 3 periods of 1994, 2004 and 2014. And then the basic characteristics and evolution rules of valley settlements in the region are concluded in detail. The results show that the valley settlement is the most important form of settlement in the upper reaches of Min River. Throughout the basin, it was loosely shaped, while in the local flat terrain it was aggregated. In the 1994-2014 years, the total area of the valley settlement was expanded, and the settlement density showed signs of decline in the local range after the first agglomeration. The overall shape of the settlement changed from regular to irregular. The distribution characteristics of patches in the valley settlements are as follows:on the elevation, the whole gradually moves toward the low elevation; on the slope, the valley settlements gradually shifted to low slope areas, then the valley settlements moved to 5°-35° area; on the slope aspect, the distribution of patches in the valley settlements was mainly migrate from the North, East, West and Northwest of the 1994-2004 years to Southeast, South, Southwest and West in 2004-2014 years.
