Abstract: Taking Yujin town in Qianwei county for example,selecting land-use pattern map of 1997 and 2008 as basic data,this study analyzed landscape pattern characters of Yujin with support of software ARCGIS 9.3 and landscape index.The results showed that the districts of land-use changes in research period were mainly along the border of Min river,Leyi Highway,the road of G213 and the west of the study area.The transition possibility of land-use pattern area was in such descending order: orchard land > traffic land > rural settlements land > cultivated land > forest land > unused land > special land > urban land.The landscape matrix of 1997 and 2008 were both cultivated land,and the agricultural landscape was becoming more fragmented,while urban landscape tended to be centralized.The problem of land-use in this region was that the degree of fragmentation index of rural settlement land was high and typical of mountain district features,which was unfavorable for carrying out the strategy of linking transform of urban-rural construction land.Thus,more attention should be paid to the plan of land consolidation and new rural construction.
