摘　　要：运用多元回归分析方法研究不同污染区生长的植物叶片的生理生态指标的变化与大气硫酸盐化速率及氟化物浓度的关系。结果表明,植物的叶面积(LA)、叶绿素总量(Chl)、细胞液pH值(pH)和细胞质膜透性(CML电导率)等生理生态指标的变化幅度与大气污染物含量呈显著相关。与大气硫酸盐化速率关系式为:YS=0.034XLA-0.011XChl+0.017XpH+40.0003XCML+0.034(r=0.99,p<0.001);与大气氟化物含量的关系式为:YF=0.362XLA+0.329XChl+0.814XpH+0.024XCML-4.596(r=0.947,p<0.03)。利用这些生理生态指标的变化幅度作为生物监测的指标来评价不同污染区的大气硫氧化物、氟化物的污染状况,与大气监测结果有很高的一致性,并且与实际环境污染状况相符。Multiple regression analysis was used for the investigation of the i nfluence of air pollutants (sulfate and fluorides) on the changes in physio-ecological character istics in the leaves of 48 plant species distributed at 8 site in Foshan city and one site in Dinghus han Nature Reserve as control. The results showed that the changes in leaf area(LA), total chloroph yll contents(Chl), cell liquid pH values(pH) and cell membrane leakage(CML) (electronic conductance ) exhibited significant correlation with pollutant contents in leaves. Linear regression equ ation between physio-ecological changes and pollutant content in the air was YS = 0.034XLA-0.0 11XChl +0.017XpH +40.0003XCML+0.034(r=0.99, p<0.001)for sulfation rate, and was YF =0.36 2 XLA+0.329XChl+0.814XpH +0.024XCML-4.596(r=0.95, p<0.03)for fluorides. The application of physio-ecologic al changes in plants as biological monitoring indicatoss of air pollution was consistent with actual environment condition.
