摘要:
内蒙阿拉善地区植物、土壤的元素背景特征及其相互关系的研究结果表明:53种植物的9种元素(Zn、Cu、Ni、Pb、Cd、Co、Cr、V、Mn)背景含量有很大差异。不同生活型植物背景值也各异,总的规律为:Mn>Zn>V>Cu>Ni>Cr>Pb>Co>Cd;同种植物的元素含量在不同群落中有明显差别,但都在同一个数量级。土壤9种元素的背景含量均以Mn含量最高,其次为Zn和V,Cd的含量最低;不同上类各剖面各种元素的垂直分布规律为底层或表层的元素含量高于中间各层。土壤元素背景值都高于植物背景值,前者一般为后者的2~20倍。植物对元素的吸收系数以Cd最大,Cr最小。土壤元素含量与有机质含量的相关性因土类不同而异:沙土的有机质含量最低,只有Zn含量与有机质相关性显着;而盐土的有机质含量最高,有Co、Cd、Mn、Ni、Cr、Zn6种元素含量与之显着相关。
Abstract:
The characteristics of the background element values in plants and soils and their relationships in Alashan Desert,Tuner Mongolia were studied.The results showed that the background values of nine elements(Zn,Cu,Ni,Pb,Cd,Co,Cr,V,Mn)in 53 plants were obviously different.The hackground values in different life forms of plants were arranged in Mn>Zn>V>Cu>Ni>Cr>Pb>Co>Cd.The nine element contents of the same species in different communities were evidently different.For the background values of the 9 elements in soils in that area,Mn was the highest,Zn and V were relatively low,while Cd was the lowest.The vertical distribution of 9 element contents in different soil types were that the down-layer or top-layer had higher element contents than the middle-layer.Soils contained heavy metals much higher than plants,with the difference of 2~20 times more.The absorption coefficient of Cd in plants was the highest and the Cr the lowest.The correlationship between the element contents and the organic matter contents in different soil types was different.Sandy soil had the hashest organic matter contsnts,and only Zn had some significant correlation with the content of organic matters.Saline soils had the lowest organic matter coments,and six elements,Co,Cd, Ni,Mn,Cr,Zn,had significant correlation with the organic matter contents.
