Taking Zhaozhuang Village of Yan’an Cty in the typical loess hilly and gully area as a study area the landuse change from 2000 to 2006 was analyzed.According to coefficients of ecosystem service value (ESV) by Xie Gaodi et al.

the ESV of landuse system was estimated and the coefficient of sensitivity way also analyzed.Results indicated that landuse of the study area changed to some extent during the past 6 year and decreased farmland and increased unused land were the main types.The total ESV decreased by 329 200 and its change rate was 1.86%.The ESV s of unused land residential-co nstructed land

forest land and shrubby grassland increased

while the ESV s of farmland

orchar

and water area decreased.Eight types of ecosystem service functions were decreased

while recreation and culture increased.The analysis of the coefficient of sensitivity indicates that the coefficient of ESV adopted is inelasticity

the result is reliable and the ESV coefficients are suitable.Landuse structure should be pertinently adjusted according to changing characteristics of ESV.
