Abstract: Based on fixed and consecutive measurements of soil moisture in hilly area of loess during wet and dry years,spatio-temporal relationships between land use types and their struc-tures were analyzed.The results are as follows:(a)the effects of land use on soil moisture are sta-tistically different in dry year,but not in wet year;(b)the annual changes of soil moisture during wet year are consuming type for shrub land,and balance type and increasing type for intercrop-ping land,orchard,woodland,grassland,fallow land and cropland.However,these changes of soil moisture during dry year are consuming type for all land uses;(c)from wet year to dry year,profile types of soil moisture change from decreasing type to fluctuation type,and from fluctua-tion type to increasing type;and(d)soil moisture of single land use structure has increasing trend from hill top to bottom,but complicated distribution patterns are found for multiple land use structure along slopes.

Key words: soil moisture, land use type, land use structure, hilly area of loess
