目的:中国树花对乌鲁木齐南郊空气污染生物指示作用的探讨.方法:采用电感耦合等离子光谱直读法测定移植地衣内重金属含量的变化.结果:地衣体内被测定出的重金属元素种类和含量与移植时间的长短之间存在显著性差异.对照组中,中国树花体内仅测出2种元素,其中Fe和Mn的含量分别为1.2915±0.054μg·g~(-1)和0.0261±0.001μg·g~(-1).移植1个月后测出Al、Fe、Mn、Zn等4种元素,其含量分别为0.68±0.036、0.706±0.086、0.021±0.016和0.061±0.005μg·g~(-1);移植3个月后测出Al、Cr、Cu、Fe、Mn、Ni、Zn等7种重金属,其含量分别为0.285±0.039、0.0032±0.001、0.004±0.002、0.499±0.133、0.106±0.015、0.011±0.01、0.011±0.01、0.038±0.002μg·g~(-1).结论:中国树花在生物评价乌鲁木齐南郊空气污染方面具有一定的研究价值.

Objective:To study the bio-indicative role of Ramalina sinensis Jatta.to environmental pollution in southern suburb of Urumqi.Method: Heavy metal constituents of the lichen specimens from different transplanted site and their variation were determined by means of atomic emission spectroscopy(ICP-AES).Result: It was tested that the types and amounts of heavy metals were increased with the elongation of transplanted time,and the element concentrations in that transplanted lichens showed great differences among different areas.In the comparison group only two elements,Fe and Mn were examined,the concentration were1.2915±0.054 μg·g~(-1) and 0.0261±0.001μg·g~(-1) respectively;after one month of transplantation,four more elements Al,Fe,Mn and Zn were found in the lichen specimens and the concentrations of those elements were 0.68±0.036,0.706± 0.086,0.021±0.016 and 0.061±0.005 μg·g~(-1);after three month,following seven more elements Al,Cr,Cu,Fe,Mn,Ni and Zn were detected and the concentration were 0.285±0.039,0.0032±0.001,0.004±0.002,0.499±0.133,0.106±0.015,0.011±0.01,0.011±0.01,0.038±0.002μg·g~(-1) respectively.Conclusion: It has been proved that the variation in the heavy metal contents of lichen species can be used a valuable indicator for the evaluation of environmental pollutions.
