摘要：城市森林土壤能储淤城市环境中的重金属污染元素,影响土壤环境质量。文章对广州市的城市森林区域中土壤重金属的污染状况进行研究,应用单项污染元素指数和综合污染指数对广州市城市森林土壤进行环境质量评价,结果表明:广州市机场高速林带林区土壤中As、Pb、Cd三重金属污染元素超标,广深铁路林带林区土壤中Cd重金属元素超标,其他各林区严格控制环境重金属污染物未超标;帽峰山森林公园土壤重金属综合污染指数最低,表明森林群落对重金属污染元素的消减作用明显。土壤酶活性可以表征森林土壤中重金属污染状况,森林土壤中As、Cu、Zn含量与过氧化氢酶活性呈显著负相关性;对可能影响城市森林土壤重金属含量因素的10个因子进行主成分分析,建立了城市森林土壤环境质量评价综合模型。
Heavy metal pollution element of soil can be stored and the soil environment quality can be affected by the urban forest. This article study heavy metal pollution condition and evaluate the environment quality by the indexes of monomial and synthetical pollution of the soil heavy metal. The results showed that contents of As, Ph and Cd exceeds the allowed standard at the airport forest belt region soil, and Cd also in the train forest belt of Guangzhou-shengzhen, and other strict control environment heavy metal pollution has not exceeded in other various forest regions; The synthetical pollution index is lowest in the Maofengshan forest park because the forest has function that can reduces the contents of heavy metal in soil; The negative correlation behaved remarked between the contents of heavy metal As, Cu, Zn and the soil catalase activity, it indicated that soil enzyme activity may be the keen reflection of soil heavy metal pollution condition; Principal component analysis was used to establish the forest soil environment quality evaluate unified model by analysing the possibility 10 factors on the soil heavy metal pollution at the Guangzhou urban forest soil.
