In this paper presented are results of a study on quality and pollution of soil environment by monitoring in Hai'an county,which is located in Central Jiangsu province. The present situation of the soil environment quality and pollution are evaluated by Nemerow integrated index method and standards such as GB/T18407.1-2001, DB32/T343.1-1999 and GB15618-1995. The county has a total of 5.30*10⁴ hm² of farmland, or 97.7% of the county's total, in compliance with the national and local environmental norms for production of non-hazard agricultural produce (vegetables, grain, cooking oil); With the standard (GB/T18407.1-2001) as the norm for assessment of the natural background value of the soil, the integrated pollution index of the county is 0.86, falling into the category of "clean". About 79.3% of the soil is of Grade One (clean), Factors contributing to the soil pollution are in the order of As > Cr > DDT > Hg > Cu > Pb > Cd > benzene hexachloride, which is mainly the result of some traditional cotton fields having been slightly contaminated with agro-chemicals (DDT, Hg, Arsenic products) and the patterns of land use and pesticide utilization in the 70-80s. In terms of regions amd severity of pollution, the Lixiahe Region > coastal region > the Riverside region. Based on the research results, strategies for utilization and remediation of the soils are brought forth.
