摘要
以哈尔滨市常见的19种绿化植被为主要研究对象,经过野外调查和室内分析对19种植被的根、枝、叶内重金属元素(Cu、Zn、Pb、Cd)总量进行分析测定。结果表明:植被对重金属的富集和转运因植物种类、部位及重金属种类而不同。依据植被对重金属的富集和转移能力不同,进行聚类分析得出,榆叶梅和蒙古栎对土壤中重金属元素Zn、Cd的富集和转移能力都很强;垂柳、旱柳、银中杨、梨树、山荆子、山槐对土壤中重金属元素Cu、Pb的富集和转移能力都较强;榆树、紫丁香、黄菠萝对土壤中重金属元素Cu的富集和转移能力较强;云杉、山杨、红松、色木槭、暴马丁香、白桦、大果榆、山里红对土壤中重金属元素Cu、Zn、Cd的富集和转移能力较强,对土壤中重金属元素的Pb富集能力也比较强,但转移能力弱。
In this paper,the total content of heavy metals(Cu,Zn,Pb,Cd)in the root,branch and leaf of 19 species of common plants of Harbin was investigated and determined by field investigation and laboratory analysis.The results showed that heavy metals enrichment and translocation by plants differed with plant species,their parts,and kinds of metals.According to the different enrichment coefficient and yranslocation factors of heavy metals by plants and showed by clustering analysis,Amygdalus triloba Lindl.and Quercus mongolica Fisch.had a higher capability of accumulating and shifting Zn,Cd;Salix babylonica Linn,Salix matsudana Koidz.,Salix alba var.Tristis,Pyrus sorotina,Malus baccata Linn.and Albizia kalkora Roxb.had a higher capability of accumulating and shifting Cu,Pb;Ulmus pumila L, Syringa oblate and Phellodendron amurense Rupr had a higher capability of accumulating and shifting Cu,Cd;Picea asperata Mast.,Populus davidiana Dode.,Pinus koraiensis Siebold.,Acer mono Maxim.,Syringa amurensis,Betula platyphylla Suk.,Ulmus macrocarpa Hance.and Crataegus pinnatifida Bge.had a higher capability of accumulating and shifting Cu,Zn,Cd and a higher capability of accumulating Pb,but they had a lower capability of shifting Pb.
