摘  要：
以甘肃省康乐县第2次土地调查Shape数据为源数据,在Arcgis的支持下,运用景观格局原理和Frag-states软件,综合利用各种斑块面积指数、斑块边界指数、斑块形状指数、斑块密度指数等指标,对甘肃省康乐县景观格局特征进行了定量分析.结果表明:康乐县的优势景观为耕地、林地和草地,分别占全区土地总面积的63.51%、12.48%和9.27%,其他景观类型呈补丁状分布;各景观类型面积大小差异较大,与人类活动有很大的关系;外界干扰影响了一系列斑块性质;研究区内景观类型发育成熟,景观类型较多且分布均匀,同时,景观结构较为简单,异质性较低,其多样性指数、均匀度指数和破碎化指数分别为1.560 3、0.520 8和0.032 4.

摘  要：
Taking the second land survey data as the data source,the landscape pattern of Kangle County of Gansu Province was analysed under the support of Arcgis by using landscape pattern theory and Fragstates software,and various plaque area index,patch boundary index,patch shape index,and patch density index were comprehensively used.The results showed that dominant landscapes in Kangle County were mainly farmland,forest land and grassland,they accounted for 63.51%,12.48% and 9.27% respectively in the study areas,and other landscape types were patch shape distribution in the study area.The area size of each landscape were greatly different,which were effected greatly by human activity.The landscape in Kangle Country were mature,abundance and symmetrical,at the same time,landscape structure was simple,and the heterogeneity was low,the diversity index,evenness index and fragmentation index were 1.560 3,0.520 8 and 0.032 4 respectively.
