土壤铅污染对城市园林植物的影响

作为城市生态系统的重要组成部分,园林植物在城市生态环境的保护和平衡中具有十分重要的作用。伴随着城市化进程,土壤Pb污染已成为制约人类生存和发展的首要环境问题,并受到政府部门和科学家的普遍关注。本文从园林植物形态、生长发育、保护酶系统、养分分配、重金属迁移等方面综述了土壤Pb污染对城市园林植物的影响的研究现状,并分析了研究中存在的不足之处。

Effects of Soil Pb Contamination on Urban Garden Plants

As one of the most important components in the city ecosystem,garden plants play a key role in the ecological environment protection and balance of cities.Soil Pb pollution has become one of the most important environmental problems and received more and more attention of the government and scientists.To effectively understand the ecological responses of garden plants to soil Pb pollution,this paper deals with recent researches into the effects of soil Pb pollution on garden plant morphological and growth character,protective enzyme system,nutrients distribution and transformation of heavy metals.Furthermore,an analysis is made of these researches.
