摘要: 采用野外生态学调查和实验分析相结合的方法,对鞍山市内和市郊所选的5个样点苔藓植物的种类、分布及各样点大气净度指数值(IAP)和苔藓体内Pb、Zn、Cu、Cd、全S等污染物的含量及其与环境污染的关系进行了综合研究和分析。结果表明,严重污染区,包括样点鞍钢,苔藓植物少于5种,IAP值<5, 苔藓体内污染物的含量范围是(mg·kg-1):Pb(112~149)、Zn(401~477)、Cu(35.8~38.5)、Cd(2.45~3.53)、S(2200~3100);污染区,包括样点立山公园和二一九公园,苔藓植物种数15~30, IAP值5~25, 污染物在苔藓体内的含量范围是(mg·kg-1):Pb(31.2~44.6)、Zn(120~199)、Cu(9.40~17.6)、Cd(1.02~2.42)、S(1400~2600);相对清洁区,包括样点烈士陵园和千山,苔藓种数多于40种,IAP值>30, 污染物在苔藓体内的含量范围是(mg·kg-1):Pb(15.4~25.6)、Zn(84.3~135)、Cu(5.24~11.5)、Cd(0.64~1.99)、S(800~2100).

Abstract: By means of ecological survey and laboratory analysis, a comprehensive study on species number, distribution, index of atmospheric purity (IAP), content of Pb, Zn, Cu, Cd, total Spollutants in bryophytes, and their relationships with environmental pollution at five monitoring sites of Anshan city were carried out.In the seriously polluted region, including Anshan Steel & Iron Company, the species number of bryophytes was less than five; the IAPvalue was smaller than five; the pollutant content (mg·kg-1 )in bryophytes was as follows: Pb(112~149), Zn(401~477), Cu(35.8~38.5), Cd(2.45~3.53), S(2200~3100).In the polluted region, including Lishan Park and Eryijiu Park, the species number of bryophytes ranged from 15 to 30; IAPvalue ranged from 5 to 25; the pollutant content was as follows: Pb(31.2~44.6), Zn(120~199), Cu(9.40~17.6), Cd(1.02~2.42), S(1400~2600).In the basically unpolluted region, including Lieshi Lingyuan and Qianshan, the species number of bryophytes was more than40; IAPvalue was larger than30; the pollutant content was as follows: Pb(15.4~25.6), Zn(84.3~135), Cu(5.24~11.5), Cd(0.64~1.99), S(800~2100).
