Using single factor to estimate pollution situation of five zones in Harbin, its result shows that the pollution situation of cadmium and hydrargyrum is very serious in the public greenbelt. The pollution situation of plumbum is very severe in the road greenbelt.

用单因子评价哈尔滨市五个功能区的污染情况，结果是镉和汞污染较重的是公共绿地，铅污染较重的是道路交通绿地，市郊农业区的铬含量相对较高。

In this thesis, the present situation of heavy metals pollution and the physical and chemical properties of soils and the enrichment situation of heavy metals (Cd、 Hg、 Pb and Cr) in the vegetable body in the Harbin city greenbelt was investigated and evaluated. The results were showed as follows:The four heavy metals all polluted greenbelt soil by different degree in Harbin. The pollution of hydrargyrum is the most serious and reaches to the heavy pollution. The next pollution is plumbum, cadmium and chrome.

本文针对哈尔滨市区城市绿地重金属污染状况、土壤的理化性质，以及重金属(Cd、Hg、Pb和Cr)在植物叶片的富集情况进行了分析，并且对哈尔滨市区重金属污染状况进行了综合评价，结果表明：(1)哈尔滨市绿地土壤表层这四种重金属都有不同程度的污染，其中以汞的污染最为严重，达到了重污染；其次是铅和镉，铬的污染较小。

The compound pollution sign exists in the soil between total cadmium, total hydrargyrum, total plumbum and chrome. The prominent correlation exists in total cadmium and total plumbum. The correlation coefficient is very lower between heavy metals in the vegetable body. The correlation coefficient is very prominent between cadmium and plumbum in the vegetable body. The correlation between vegetable and soils heavy metal content of the cadmium is very prominent and others is very lower.

土壤中全镉、全汞、全铅和全铬这四种重金属之间存在着复合污染的迹象，其中全镉和全铅存在极显著的相关性；植物体内重金属之间的相关系数很低，只有镉和铅具有显著相关性；植物和土壤重金属含量的相关关系只有镉的含量呈显著关系，其它相关性较低。
