不同污染区对绿化树种可溶性糖含量的影响

Soluble Sugar Content of Landscaping Tree Species under Various Pollution Areas

为了了解兰州市大气污染的情况,选择兰州市的主要绿化树种为研究对象,对叶片中的可溶性糖含量进行了测定,并且运用statistic软件进行分析。结果表明:同一树种在不同污染区的可溶性糖含量不同,存在极显著性的差异,同一污染区的各种绿化植物的可溶性糖含量也存在显著性的差异。5种树种的抗污染能力为:杨树>小叶黄杨>椿树>国槐>圆柏,兰州主要功能区的污染程度为:兰炼厂区>兰化厂区>橡胶厂>西关>西站>交大>兴隆山。研究结果可以为兰州市的大气污染治理提供理论和实践依据。

Five major landscaping tree species were studied to understand air pollution status of Lanzhou City,Gansu Province,with data analyzed by statistic software.Results showed that plant species in various pollution areas varied from each other and had remarkable significance.Five species in the same pollution area had different soluble sugar contents,with sequence of pollution tolerance ability ranking as poplar,Buxus microphylla,Ailanthus altissima,Sorphora japonica and Sabina chinensis L.The study can offer theoretical and practical basis for air pollution control of the City.
