| 摘 要： | 利用2006年夏季实地测量的植物叶片滞尘数值，得出常绿乔木、落叶阔叶乔木、灌木以及草地4种不同植物类型的平均滞尘能力，再将其与用遥感方法估算出的叶面积指数以及植被统计数据相结合，评估了门头沟区自然植被总体的滞尘能力、滞尘量与滞尘效益.结果表明: 自然植被具有明显的滞尘功能，门头沟区自然植被的年滞尘量为39.47×104 t，由此带来的滞尘效益价值为67.10×106元；灌木林和落叶阔叶林2种植被类型，是研究区自然植被滞尘能力和年滞尘量的主要组成部分；常绿乔木的滞尘时间长于其他任何植物种类，其年滞尘量与滞尘能力所占比例有所增加.

| Abstract: | Dust absorption ability measurement of plant leaves were taken in summer 2006 inMentougou District, Beijing. Those measured plant species were divided into four different vegetation classes, i.e. evergreen tree, deciduous broadleaved tree,deciduous shrub and herb. The average dust absorption of the same vegetation class represented its own ability. The dust absorption ability, amount and efficiency of overall natural vegetation were evaluated by RS and GIS means based on statistical vegetation data. The result showed that natural vegetation has obviousfunction on dust absorption. The dust absorption amount due to natural vegetation in Mentougou District is 39.47×104t/a, which brings a benefit of dust absorption of RMB 67.10×106 yuan. Shrub forest and deciduous broadleavedforest are the chief components of dust absorption ability and amount in study area; the dust absorption time of evergreen trees is longer than that of other plants, and thus their dust absorption amount and ability are somewhat increased. |
