| 摘 要： | 对红花银桦在420d的污染环境下，叶、枝、主干、根等器官对大气SO2和氟化物的净化能力的研究表明，红花银桦在长时间的污染条件下，对SO2、氟化物等污染气体具有较强的抗性和吸收、净化能力，并且枝、主干和根对污染物的吸收、净化能力都比抗性强的小叶榕高。叶片含S量达2．963g·kg^-1，枝可达3．371g·kg^-1，主干和根分别为1.604和1．510g·kg^-1。其中，枝的含S量不仅是清洁区的2．3倍，也是小叶榕枝的2．3倍。叶片含F量达678．58mg·kg^-1，是清洁区的7．26倍；枝、主干、根含F量是小叶榕枝、主干和根的2．0倍多。

| Abstract: | The purification ability of leaves, branch, trunk and root organs of Grevillea banksii to air SO2 and fluoride in environmental pollution 420 days indicated that under the conditions of long time environmental pollution, G. banksii had more intensive resistante and the absorption and purification ability to SO2 and fluoride, furthermore the absorption and purification ability of the branch, trunk and root was higher than the intensively resistant Ficus microcarpa. The leaves sulphur content was up to 2.963 g · kg^-1, the branch sulphur content was up to 3. 371 g · kg^-1, the trunk and root was respectively 1. 604 and 1. 510g · kg^-1 ; the branch sulphur content was 2.3 times higher compared to the control area. The branch sulphur content of G. banksii was 2.3 times higher compared-to the branch of F. microcarp. The leaves fluoride content was 678.58 mg · kg^-1 , 7.26 times higher compared to the control area. The branch, trunk and root fluoride content of G. banksii was 2.0 times higher compared to F. microcarp. |
