摘　　要：探讨涪江流域地貌特征对人口分布、经济发展的约束作用,可为区域人口合理布局提供科学依据,为统筹人口、社会经济、地理环境协调发展提供决策支持。基于ArcGIS空间分析模块,对发源于青藏高原东缘与四川盆地过渡地带的涪江流域各县域单元的地貌特征及其与人口、经济格局之间的关系进行分析。结果表明:断裂活动使研究区地形起伏度随海拔增加呈增大趋势;研究区人口布局、经济布局呈现向海拔与地形起伏度低值区集聚的态势。地貌状况对盆地-山地过渡区域人口分布和经济发展的影响作用尤为明显,在涪江流域表现为县域平均海拔、地形起伏度与所在县区人口、经济指标的显著负相关性。The exploration of the binding effect of geomorphic features on population distribution and economic development in Fujiang river basin can provide a scientific basis for promoting the rational distribution of regional population and give decision support for coordinated development of population,socialeconomy and geographical environment.Based on the spatial analysis module of ArcGIS,the relationship between geomorphic features and population and economic pattern of 31 counties located in the transition zone between Qinghai-Tibet plateau and Sichuan basin is discussed.The results indicate that the relief amplitude has increased with the increase of elevation because of fault differential activity;the population distribution and economic distributionof the study area have shown the tendency of converging to the low-value areas of elevation and relief amplitude.Geomorphic conditions have an obvious influence on the population distribution and economic development in the basin-mountain transition region.In Fujiang river basin,the average elevation and relief amplitude of the counties are negatively correlated with its population and economic indicators.
