对银川市西夏区的四个针叶树种在三个不同粉尘污染区的春季滞尘能力进行测定与分析,结果表明:各树种在不同的粉尘污染区均表现出明显的滞尘效应;不同树种的滞尘能力存在明显差异;树种的滞尘能力与降尘环境、滞尘时间等因素有关;随着时间的延长,四树种在不同的粉尘污染区的滞尘能力呈增大趋势;几种针叶树种的滞尘能力由强到弱的顺序为:侧柏>白皮松>桧柏>云杉。
The dust-holding capacity of four conifers in Xixia district of Yinchuan in three different dust-polluted areas in spring was measured and analyzed. The results showed that: the dust-proofing effect was obvious in different dust polluted areas; Dust retention capacity of trees was significantly different. Dust retention capacity of tree species was related to dust deposition environment and dust retention time. With the extension of time, the dust retention capacity of four tree species increased in different dust pollution areas. Some conifer species The order of dust retention capacity from strong to weak is: Arborvitae> Pinus bungeana> Cypress> Spruce.
