苔藓植物含硫量与大气SO_2间对应关系的应用研究

APPLICATION AND STUDY OF HYPNUM SP.THUIDIUM SP.PLANT ABOUT AIR IMPAET ASSESSMENT

本文通过对贵阳市区１３个采样点和大气监测采样分析，确认苔藓植物移植挂片含Ｓ量与大气中ＳＯ２浓度密切相关。环境在ＳＯ２污染状况下，以苔藓含Ｓ量的为因变量，环境中ＳＯ２浓度为自变量的线性回归方程，可以很好地测算大气ＳＯ２浓度，并评价大气污染等级。

This paper describes grimmia pulvinata last and air determine sample analysis of fifteen point in Gut Yang.Meanwhile, relationship of plant contained S and SO2 concentration in air is determined. Linear regression may be used to compute air SO2 concentrtion at the pollution state of environment impact assessment the degree of pollution.
