由于西安市环境污染问题较为严重,特别是大气污染,所以西安市已经全面实施公园绿化、城市绿化建设工作,并且也取得了一定的效果,但却未完全形成整体性的景观效果。屋顶绿化能够为节约土地、治理大气污染、建设整体景观和缓解城市热岛效应环境做出重大贡献。本文主要分析了西安市屋顶绿化的现状、适宜的绿化类型和在法律保护下实施屋顶绿化的必要性以及实施后出现的环境问题提出了相应的措施。
Due to the serious environmental pollution problems in Xi’an, especially the air pollution, Xi’an has fully implemented park afforestation and urban greening construction and has achieved certain results, but it has not yet formed a complete landscape effect. Roof greening can make a significant contribution to saving land, managing air pollution, building the overall landscape and alleviating the urban heat island environment. This paper analyzes the status quo of roof greening in Xi’an, the suitable types of greening, the necessity of implementing green roofing under the protection of law and the environmental problems after the implementation, and puts forward corresponding measures.
