摘　　要：采用贵州毕节(黔西北)、黎平(黔东南)、务川(黔东北)、兴义(黔西南)、开阳(黔中)等5个代表地区的TM/ETM卫星影像数据,依据GIS软件分析其景观格局特征。结果表明,贵州省的农村景观分布差异性比较大,景观的破碎程度较高,农业景观的完整性较差,景观除了聚落景观的分维数较低外,其他农村景观的分维数比较高。其农村景观的斑块形状极不规则,形状无规律性。Using TM/ETM satellite image data of 5 represent areas Guizhou Province,the city of Bijie（north of Guizhou Province）,Liping（southeast of Guizhou Province）,Wuchuan（Northeast of Guizhou Province）,Xingyi（southwest of Guizhou Province）,Kaiyang（the Middle of Guizhou Province） from 2000,based on GIS software to analyze the characteristics of landscape pattern.The results showed that the rural landscape of the Bijie city had relatively large differences in the distribution,a higher degree of landscape fragmentation,poor integrity of the agricultural landscape,in addition to the lower fractal dimension of village landscape,the fractal dimension of the other rural landscape was relatively high.The rural landscape shapes of the patch were irregular and non-regularity.
