In this paper authors handled the marine environment investigation data about bottom sediment pollution on 43 stations in the coastal areas of Beibu Bay in 1984-1985 by the included angle cosine method of Q type in cluster analysis, sediments pollution classificatioa The bottom sediments are divided into three kinds: the type I belongs in unpolluted or very little pollution, it takes 37.2%. The type Ⅱ~Δ is heavy-metal pollution system which takes pb-pollution as main part. It was considered as a light pollution type, taking 32. 6%. The type Ⅲ~Δ is light-to-medium pollution in which petroleum and several heavy metals(Pb, Hg, Zn, etc) are main pollutants, taking 30. 2%. Analysis shows that the pollution-type order is Ⅲ~Δ ,Ⅰ~Δ,Ⅱ~Δ away from seashore of marine area in Baibu Bay, which tallies with formation cause analysis.

The soils in most part of Dalian areas are not polluted by oil or metals, while in some limited areas the soils are lightly polluted at present. Because of irrigation with waste water containing Hg, the soil Hg contents in 40% sampling locations reached medium pollution level. Bap in soils from urban areas of Dalian are more than midium pollution level in 32.6% sampling locations, and more than heavy pollution level in 17% locations because of the influence of air pollution. The main controlling measures are as follows: A. Controlling the pollution sources and raising the exploitation efficiencies water, coal and oil. B.Readjusting the patterns of indus trial distribution. C.Controlling the discharge of pollutants from rural industries. D.Monitoring the pollution of crops and vegetables in the polluted areas.

大连地区是辽东半岛的重要组成部分。本区土壤中,油及大部分重金属基本上为未污染,少部分为轻污染。由于引用含汞污水灌溉,40%采样点土壤汞达到中度污染。受大气污染影响,大连市区土壤中苯并(a)茈有32.6%样点超过中度污染,17%超过重度污染。土壤污染的防治,主要是控制污染源,提高水、煤、油资源的利用率;合理调整工业布局;搞好乡镇工业环境保护;进行土壤污染区作物和蔬菜监测。
