摘　　要：以原阳县1980—2015年5期土地利用数据为主要数据源,借助ENVI4.3、ArcGIS10.5、Fragstats4.2、SPSS20.0平台软件,采用转移概率矩阵、景观指数分析以及主成分分析等数据处理方法,提取原阳县1980—2015年的耕地变化信息,分析其变化规律及影响因素。结果表明:(1)耕地是该地区的优势景观地类,其面积占土地总面积的79.5%,耕地的优势度指标高于其他地类,其中旱地的优势度高于水田。(2)耕地的总面积总体呈现上升趋势,对该地区景观的主导作用越来越突显,同时耕地斑块的形状一直保持较为复杂的形态,耕地作为最大斑块类型其优势度有所下降。(3)影响耕地景观格局变化主要因素为人民生活水平、经济发展与农业科技水平,人口因素和自然因素对其影响较小。The land use data of five phases from 1980 to 2015 in Yuanyang county were taken as the main data source,with the help of some platform softwares,such as ENVI4.3,ArcGIS10.5,Fragstats4.2 and SPSS20.0,and data processing methods such as transfer probability matrix,landscape index analysis and principal component analysis were used to extract the change information and to analyze the change law and reasons of cultivated land in Yuanyang county.The results show:1)Arable land is the dominant landscape type in this region,whose area accounts for 79.5%of the total land area.The dominance index of cultivated land is higher than that of other land types,among which the dominance of dry land is higher than that of paddy field;2)The area of cultivated land generally shows a tendency of rising,the leading role of the landscape of the region is more and more highlighted,the shape of the cultivated land patches has remained relatively complicated shape,and the dominance of arable land,as the largest patch types,has decreased in a way;3)The main factors that affect the change of cultivated land landscape pattern are living standard,economic development level and agricultural technology level.The population and natural resources have little influence on it.
