摘要
本文对埃里温-亚美尼亚首都城市绿色基础设施中两种常绿树种西柏(Thuja occidentalis L.)和维吉尼亚杜松(Juniperus virginia)的金属积累潜力进行了初步研究。研究了两种常绿树种的生长状况、夏末和冬末针叶重金属含量的季节变化以及植物的生物浓度因子。寿命的减少表明这两种常绿树种都不适合种植在交通繁忙的街道或靠近工业污染源的地方。
ABOUT HEAVY METAL ACCUMULATION POTENTIAL OF SOME EVERGREEN TREES IN GREEN SPACES OF YEREVAN (ARMENIA)
This article presents the final research on the study the metal accumulation potential of two evergreen species Thuja occidentalis L. and Juniperus virginiana involved in the green infrastructure of Yerevan-Armenia’s capital city. We studied the condition of both evergreen species, seasonal variations of heavy metal contents in their needle at the end of summer and winter, and the bio concentration factor of plants. The decreased longevity shows that both studied evergreen species are inappropriate for planting in the streets with heavy traffic or close to industrial pollution sources.
