树木被广泛认为是大气中气体和颗粒污染物的有效清除剂。最近的工作，城市气溶胶沉积到林地允许空气中的气溶胶浓度的植树策略的影响进行量化，并在规划过程中考虑。通过确定潜在的种植地点在地方当局的区域，并将其应用在一个分散和沉积模型，减少PM10的环境浓度的潜在幅度，可通过城市植树，已被量化为两个英国城市。作为规划环境信息系统的一部分，基于规划决策的流程图纳入了模型的输出，以便就土地使用规划做出决策，从发展计划和战略规划到发展控制。这样，对于任何导致当地PM10水平升高的新开发项目，都可以评估植树的缓解效果，在某些情况下，减少的PM10可能足以达到空气质量目标。(c)2006爱思唯尔有限公司版权所有。
Trees have been widely quoted as effective scavengers of both gaseous and particulate pollutants from the atmosphere. Recent work on the deposition of urban aerosols onto woodland allows the effect of tree planting strategies on airborne aerosol concentrations to be quantified and considered within the planning process. By identifying the potential planting locations in the local authority area, and applying them within a dispersion and deposition model, the potential magnitude of reduction in the ambient concentration of PM10, achievable through urban tree planting, has been quantified for two UK cities. As part of the Environmental Information Systems for Planners (EISP), flow diagrams, based on planning decisions, have incorporated output from the model to make decisions on land use planning ranging from development plans and strategic planning, to development control. In this way, for any new developments that contribute to the local PM10 level, the mitigation by planting trees can be assessed, and in some cases, reductions can be sufficient to meet air quality objectives for PM10.
