论文摘要：In this study， Herbicide Dinoseb (２-see-butyl-４， ６-dinotrophenol) was used as the main chemical found in the groundwater of the research area。 The major mechanism found to influence the fate of herbicide transport in soil column is sorption and the most famous method in determining sorption property of chemicals in soil column is batch techniques。 Sorption of herbicides onto root mass and soil organic matter has practical implications to the movement and distribution of herbicides。 Herbicide binding in a soil can be weak or strong depending on the amount of organic matter present and the degree of decomposition of plant residue within the soil。 Sorption is influence by some soil properties which can be seen in its spatial variation within soils although some few studies have investigated sorption variation parameters。 The study intensively studied batch experiments with Dinoseb and different soil samples。 In batch experiment， parameters are analyzed statistically and the relationships between the parameters and soil properties are investigated thoroughly。 In the study， Dinoseb sorption parameters reflect spatial variations and distributed in the research area。 Freudhch sorption coefficients of Dinoseb have genuine positive correlation with Organic Carbon contents but the relationship between the values and other soil properties， are not crucial。 In the study paper， the heterogeneity of OC content accounts to about ９０％ of variability of Dinoseb。
