Bryophytes has been widely used as a class monitor environmental pollution indicator plants. Developed countries indicates that the monitoring of environmental pollution by moss has done a lot of research work has made gratifying progress, and some of the more practical techniques and methods. China is also useful for the moss to monitor atmospheric pollution, but the research methods used a qualitative ecological indicators law, using ecological methods that observe its external morphology to estimate atmospheric heavy metal pollution, and vulnerable to a certain extent the investigators subjective factors; quantitative monitoring is relatively small, and the monitoring of the main targets is SO 2 and other gaseous pollutants in heavy metal monitoring of atmospheric pollution in bryophytes the adsorption properties of the material as well as the impact of pollutants on the ultrastructure, the relatively narrow scope of the study. Therefore, the chemical analysis of the quantitative research, qualitative study combined research bryophytes heavy metal adsorption characteristics conducive to a better understanding of moss atmospheric heavy metal adsorption rules in monitoring air pollution and ecological indicators method significance. Accordingly, this study first by moss species, growth conditions and distribution characteristics of the survey revealed the moss ecological characteristics and the correlation of air pollution. Followed by quantitative analysis of the content of heavy metals in comparing different bryophytes, analysis moss heavy metal adsorption characteristics, screening out the heavy metal accumulation ability of moss varieties as bryophytes atmospheric environmental monitoring. Again using a simple qualitative and quantitative identification of regional atmospheric heavy metal pollution - the moss bags biological monitoring method Nan'an, Jiulongpo, Jiangbei and Beibei Tianshengqiao, atmospheric quality monitoring, atmospheric pollutants stem monitoring area reveals The spatial and temporal distribution of the regularity of wet deposition and atmospheric pollutants. The results show that: the investigation points bryophyte species, frequency of occurrence and abundance of quite different. Jinfo, Tianshengqiao, Long vehicles Temple, North Hot Springs Mountain ear Cliff and other places bryophytes variety, vigorous growth; Laifeng the finest m, slots moss plant species, growing. The most the bryophyte common varieties in the survey area Juan moss genera case Brachytheciaceae, Ma Yu Hedw, scale leaf Hedw, the gray moss genus, Selaginella Hedw on. Levels of contaminants in the various monitoring points bryophytes change: Qingmuguan gt; the Tianshengqiao gt; the North Spa gt; Long car Temple gt; Laifeng gt; Mountain ear cliff. Thus every point, according to the size of the relative degree of pollution 3 the which the contaminated areas Qingmuguan, Tianshenqiao; the mildly contaminated areas dragon car Temple, North Hot Springs, Laifeng; clean area for mountain ear cliffs. In addition, according to the type of pollution, the six samples investigated in this experiment can be divided into four categories, clean area for mountain ear Cliff; mercury-contaminated areas of North Hot Springs and Long car Temple; copper nickel the contaminated areas Qingmuguan and Tianshengqiao; Zinc contaminated areas as Laifeng. Different kinds of moss on the adsorption of different pollutants, different moss species through the same point in the relative enrichment of heavy metals ability found in a variety of mosses collected in the the Institute survey sample area, the mercury adsorption stronger moss species: moss Selaginella genus, broadleaf stone moss scale leaf Hedw the the Juan Hedw gray Hedw. The stronger copper adsorption moss species: broad-leaved the stone moss and Haplocladium microphyllum moss, the Selaginella Hedw Ma Thuidiaceae, case. Of cadmium adsorption force strong moss species: broadleaf stone moss intends grass moss scale leaf Hedw, the green moss genus, Selaginella Hedw, Juan Hedw, Ma Yu Hedw. The stronger lead adsorption moss species: green moss genus, genus Selaginella moss, Juan Hedw, Ma Yu Hedw, the broadleaf stone moss intends grass moss scale leaf Hedw. The stronger zinc adsorption moss species: broadleaved stone moss, thin case of Luo moss, Haplocladium microphyllum moss proposed grass moss, green moss genus moss Selaginella
