Based on traditional statistics

the influence of different land uses on chromium(Cr) concentration in Jiutai city of Jilin province was compared

including vegetable field

dry land and paddy field.Geo-statistics was used to analyze the spatial distribution pattern of Cr in the whole study area.The variance analysis indicated that different land uses greatly affected the accumulation of Cr in the soils.The difference of Cr concentration between vegetable field

paddy field and background value was significant

whereas it was not the case for dry land.Semivariogram of Cr content in the whole area was fitted well using spherical mode1.The relatively small ratio of nugget variance to sill(14%) and large range(74.58 km) showed good spatial correlation of Cr content.Further analysis indicated that the spatial structure of Cr was isotropy.Through ordinary Kriging interpolation

it was found that the content of Cr was high in the southwest and island area of northeast due to different land use types and topographical factors.Although the spatial distribution of Cr content was mainly controlled by the shape

topography and soil character of the study area

some anthropogenic factors should not be ignored

including regulations of land management for different land use types and fertilization.
