摘　　要：为研究常见蔷薇科植物在生长期对大气中氟化物的吸收积累特征,筛选对氟化物抗性较强且易富集的物种,分别于4月、6月、8月和10月,采用酸碱浸提法测定研究区内常见的8种蔷薇科植物体内的氟含量,并根据累积变化特征对植物进行分类.结果表明:所检测的8种植物中6种植物具有一定的氟富集功能,其中红叶李、桃的氟吸收和累积程度均高于其它物种;这6种植物在其新叶生长期普遍易吸收大气中的氟化物,且在成熟期体内氟含量没有发生显著的降低,适宜在净化大气氟化物的工作中推广种植.To research on the uptake of atmospheric fluorine by familiar plants of Rosaceae during growing period,the paper has screened the species which are fluorine resistance and enrichment,determined the content of fluorine in 8 plants of Rosaceae in April,June,August and October through acid and alkali extraction method respectively,and classified plants according to the variations of fluorine accumulations.The results show that six of those plants have stronger fluorine enrichment ability than others.Especially,the levels of fluorine absorption and accumulation of both Prunus cerasifera and Prunus persica are higher than others.Furthermore,the six of those plants are easier to absorb atmospheric fluorine during new leaves growing and the contents of fluorine in these plants have no significant change in maturation period.Thus,they are recommended to be planted in the work of cleaning atmospheric fluorine.
