Abstract Taking Zhaozhuang village in typical Hilly-gully region of Loess Plateau as the study area,and selecting indexes such as diversity index,dominance index,evenness index,fragmentation index,deviation index,the dynamic changes of land-use landscape pattern were analyzed on village scale.Results show that: 1) the patch numbers and patch density increase while the mean patch area decrease during the researching period.2) the difference between landscape heterogeneity of two periods is significant;the dominance index and deviation index decrease when the indexes of diversity,evenness and fragmentation increase to some extent.3) with the policy of returning cropland to forest implementing,land-use landscape pattern of the study area have changed a lot during the past 6 years.The whole situation of eco-environment is improved;the income is increasing slightly;the industrial structure is trending reasonably.With the increasing of proportion of sideline the proportion of planting industry,breeding industry and fruit-vegetable industry decreased.And peasant income mainly comes from sideline and fruit-vegetable industry.
