Abstract:: In order to provide reference for reasonable use of land resources and protect and utilize the imperial and legacy,we calculated some landscape diversity indices under the support of GIS technology,using the indices such as patch size and amount,average fractal dimension,patch extension index,diversity index,dominance,consistency degree and fragmentation,the dynamic changes of landscape diversity in the Wulingyuan region over the past 17 years.The results showed that the total number of patch reduced by 67 from 1988 to 2005,in which farmland and woodland increased by 90 and 27 respectively,water area,orchard and the building areas decrease by 11,121 and 51 respectively;the average area and perimeter of patches increased by 4.036hm² and 966.69m separately;average fractal dimension of farmland,woodland,water area and unutilized land decreased in different degrees,while orchard and the building areas increased slightly.The characteristics of landscape heterogeneity are depicted that the consistency degree,fragmentation and diversity index increased by 0.13,0.001 and 0.27,respectively,while the dominance decreased by 0.27.During the study time,the landscape ecosystem mainly composing of farmland and building has already changed into highly heterogeneous landscape ecosystem mainly composing of farmland,orchard and building.Human activity is the main driving factors for the dynamic changes of spatial pattern of landscape in this area.
