保定市区常见灌木滞尘能力研究
|
摘要
为筛选出适用于保定市的优良绿化灌木,提高城市植被滞尘效应,选取保定市主干道以及河北农业大学西校区绿化常用的6种灌木(大叶黄杨、金叶女贞、紫叶小檗、连翘、紫叶李和紫荆)为研究对象,对其滞尘能力进行研究。结果表明:不同灌木滞尘能力差异显著,其中,保定市绿化常用灌木中大叶黄杨的滞尘能力最强,在滞尘量最高的南二环单位投影面积滞尘量可高达149.11g/m2,其次是金叶女贞,紫荆的滞尘能力最差,仅为大叶黄杨的6.57%;在农大西校区,大叶黄杨、金叶女贞与紫叶小檗均滞尘量由大到小依次表现为下部叶片、中部叶片、上部叶片;随时间推移,植物滞尘能力越来越小,3周左右达到饱和。相关分析表明,同一环境条件下叶面积指数对灌木滞尘能力起决定性作用。因此,建议保定市园林绿化灌木植物可以首选大叶黄杨与金叶女贞。
In order to select the shrub species with excellent dust retention ability and improve dust-retention effect of urban vegetation in Baoding,six kinds of common shrubs(Buxus megistophylla,Ligustrum×vicaryi,Berberis thunbergii var.atropurpurea,Forsythia suspensa,Prunus cerasifera f.atropupurea and Cercis chinensis)were selected as research objects to study their dust retention ability in main streets of Baoding and Hebei agriculture university campus.The results showed that dust retention ability had significant differences in different shrubs.Among the six kinds of shrubs,dust retention capacity of Buxus megistophylla was highest,and dust retention of per unit projected area could reach to149.11 g/m2;followed by the Ligustrum×vicaryi;Cercis chinensis was lowest,and was just 6.57%Buxus megistophylla.The dust retention quantity of Buxus megistophylla,Ligustrum×vicaryi and Berberis thunbergii var.atropurpurea were all showed:lower leaf>middle leaf>upper leaf in Hebei agriculture university campus.With time going on,the dust retention rduced,and reached saturation in about 3 weeks.The correlation analysis shows that leaf area index played a decisive role in shrub dust retention under the same environmental conditions.In general,landscaping shrubs can be considered using Buxus megistophylla and Ligustrum×vicaryi firstly in Baoding.
