    Abstract:

    By taking a typical loess hilly-gully area—Zhaozhuang village in Yan'an City as a study area and selecting indexes such as dynamic degree of landuse,trend-state index of landuse,and landscape index of landuse,dynamic changes of landuse were analyzed quantitatively on village scale.Results showed that landuse in the study area changed to some extent during the past 6 years,which was characterized mainly by decreased farmland and increased unused land.Unused land,resident-construction land,forest land,and shrubby and grass land increased in varying degrees and their dynamic degrees were 43.92%,15.35%,0.33%,and 0.17%,respectively.Farmland,orchard,and water area decreased in different degrees and their dynamic degrees were 7.45%,3.79%,and 0.20%,respectively.The trends of farmland,orchard,and water area dropped,while the trends of unused land,resident-construction land,forest land,and shrubby grassland raised,which scales were increscent.Patch number and patch density increased.The dominance index and deviation index decreased while the indexes of diversity,evenness and fragmentation increased to some extent.
