天山雪岭云杉（Picea schrenkiana）林净化空气功能研究
Study on Air Decontamination Function of Picea schrenkiana in the Tianshan Mountains
摘要
Abstract
In this paper,the functions of adsorption and filtration of Picea schrenkiana forest to the main air pollutants are analyzed by monitoring and measuring the dynamic trends of dustfall amount and TSP in Picea schrenkiana forest and the sulphur content in Picea schrenkiana leaves at different altitudes,on which the air decontamination function of Picea schrenkiana forest is evaluated.The results are as follows：（1） The dustfall amount in the forest with canopy density of 0.8 was the highest（14.04 g/（m2·30 d）） in June and July,it was increased by 4.88 g/（m2·30 d）（34.8%） compared with that in an open contrast zone,and the air decontamination value of the forest was 2.17 yuan/（m2·30 d）;（2） Rainfall and human activities affect significantly TSP concentration,the caught TSP in air over the forest can be increased by 0.052 mg/m3 compared with that in the open contrast zone,and it can be increased by 70.3% in maximum;（3） Correlation between the sulphur content in Picea schrenkiana leaves and altitude is not significant.In the threshold for injury,the sulphur content in leaves is increased with the increase of SO2 concentration in air,it is the highest（1.44 mg/g） at altitude of 2 300 m a.s.l.,and the average SO2 decontamination value of each Picea schrenkiana tree is 2.16 yuan.关键词
