摘　　要：针对云南省德宏州国土空间开发格局形成机制复杂的问题,该文提出了一种基于冗余分析(RDA)的驱动力研究方法。使用景观格局指数对各乡镇建设用地空间格局进行定量分析,以自然和社会经济数据作为潜在的驱动因子,利用RDA方法对驱动因子进行约束性排序,分析得出人口和经济因素是主要驱动因素。人口众多、经济发达的乡镇,建设用地相对面积较大,并且建设用地更趋向于聚集。此外,自然因素、农业因素、政策因素等,也与人口和经济因素有联动作用,驱动国土空间形态与结构的形成。提出新的驱动力分析方法,一方面探讨冗余分析方法在国土空间开发格局驱动力分析中的应用潜力;另一方面为云南省第一次地理国情普查成果的深化应用提供典型应用示范。According to the fact that the formation mechanization of land development pattern in Dehong Prefecture is complicated,this paper presented the method of driving force analysis based on redundancy analysis（RDA）.The spatial pattern of the construction land of each township in Dehong Prefecture was quantitatively analyzed and calculated using the landscape pattern index.The natural and socioeconomic data of each township were used as potential driving factors,and the redundancy analysis method was used to constrain rank the driving factors.The results indicated that the population and economic factors were the main driving forces for the land development pattern of Dehong Prefecture.The area of the construction land of the large population,economically developed townships is relatively large,and the construction land tends to aggregate.In addition,as well as population and economic factors,the natural factors,agricultural factors and policy factors had coupling effects on the formation of land use form and structure.This study proposed the new method that use RDA to demonstrate the main factors of driving forces of land development pattern and provides an important example for use of outcomes of Yunnan Province geographic national census.
