夏尔希里地区两种典型植物群落土壤重金属污染现状研究
Pollution status of soil heavy metals within two typical plant communities in Xiaerxili area
摘要
Abstract
In order to explore the spatial distribution and pollution status of heavy metal elements in soil of arid area on Desert-oasis Ecotone that has high sensitivity ,the level of heavy metals distribution ,vertical distribution ,correlation studies and integrated pollution index under two kinds of typical plant communities were carried out in Xiaerxili region . Results showed that heavy metal had surface aggregation phenomenon in soil ,and its content was relatively high in the 0~ 30 cm layer ,whereas remained low in the 50 ~ 60 cm layer .Various characteristic values distribution of soil heavy metals for Achnatherum splendens community was higher than those for Leymus chinensis community .For spatial distribu-tion of heavy metals ,Cr ,Cu and Pb in the western area of the study area was relatively high .Zn had a strong distribu-tion pattern that Zn tended to be high in east and low in west .Correlation analysis showed that correlations among organic matters of heavy metals for Achnatherum splendens community were stronger than those for Leymus (P< 0 .05) .In con-clusion ,the evaluation indicates that heavy metal pollution in the Leymus chinensis community under heavy metal pollu-tion index was less than that in Achnatherum splendens community .关键词
