摘  要：
以天津市5种常绿灌木为研究对象,通过实地采样与实验室分析,对5种常绿灌木不同季节的滞尘能力进行比较研究,同时探讨了不同季节蒙尘对5种常绿灌木叶绿素含量及抗坏血酸含量的影响。结果表明:不同植物滞尘能力差异显著(P<0.05),5种常绿灌木年平均滞尘能力由大到小依次为小叶黄杨7.81mg·cm~(-2)、小龙柏5.80mg·cm~(-2)、沙地柏3.68mg·cm~(-2)、大叶黄杨3.66mg·cm~(-2)、凤尾兰2.18mg·cm~(-2),凤尾兰仅为小叶黄杨的28%。不同季节植物表现出了不同的滞尘能力,大叶黄杨、沙地柏、小龙柏为秋季>冬季>春季>夏季,凤尾兰为冬季>春季>秋季>夏季,小叶黄杨为冬季>秋季>春季>夏季。不同植物之间抗坏血酸含量及叶绿素含量差异显著(P<0.05),夏季含量明显高于其它季节,抗坏血酸含量、叶绿素含量均与滞尘量呈显著负相关。

摘  要：
Taking 5 evergreen shrubs as the main research objects in Tianjin,through field sampling and laboratory analysis research methods,the dust-retention capacity of 5 evergreen shrubs in different seasons were compared.It also discussed total chlorophyll content and ascorbic acid content of 5 evergreen shrubs in the different seasons.The results showed that the dust retention capacity of different plants were significant difference(P<0.05)and 5 evergreen shrubs average annual dust retention capacity from large to small in turn,Buxus sinica var.Parvifolia was 7.81mg·cm~(-2),Sabina chinensis(L.)Ant.var.chinensis cv.Kaizuca was 5.80mg·cm~(-2) and Sabina vulgaris was 3.68mg·cm~(-2),Buxus megistophylla was 3.66mg·cm~(-2),Yucca gloriosa was 2.18mg·cm~(-2),Yucca gloriosa was only 28% of Buxus sinicavar.Parvifolia.Dustretention capacity of 5 plants in different seasons were different,Buxus megistophylla,Sabina vulgaris,Sabina chinensis(L.)Ant.var.chinensis cv.Kaizuca were autumn>winter>spring>summer,Yucca gloriosa was winter>spring>autumn>summer,Buxus sinica var.Parvifolia was winter>autumn>spring>summer.Ascorbic acid content and total chlorophyll content were significantly different among 5 plants(P<0.05).Contents of summer were significantly higher than that of other seasons,ascorbic acid content and dust-retention capacity,chlorophyll content and dust-retention capacity were significantly negative correlation.
