在北京地区,草坪品种多以冷季型草坪草种为主,这类草坪已经显现出景色单调、耗水量多、管理费用高等诸多不足之处,制约了绿化水平的进一步提高。随着建设生态型、节约型园林绿化的要求日益迫切,体现尊重自然、保护自然、再现自然的自然发展观,成为城市园林绿化建设的指导思想。本文阐述了冷季型草在水肥消耗、繁殖能力和管理费用等几方面的缺陷,着重分析了在北京已经将水资源缺乏作为影响经济发展的首要障碍之一的城市,草坪品种应向多元化方向发展。各种草坪草要因地制宜,依据其对环境的要求来配置,以达到资源的有效利用,野生地被植物对于把自然引入城市,实现城市生物多样化,具有不可替代性,应有意识的加以繁殖、调配。
In Beijing, most of the turfgrass varieties are mainly cold-season turf grasses, which have shown many shortcomings such as monotonous scenery, excessive water consumption and high management costs, which further restrict the improvement of the afforestation level. With the construction of ecotypes, the requirements of conservation-oriented landscaping are increasingly urgent, and the natural development concept of respecting nature, protecting nature and reproducing nature is becoming the guiding ideology of urban landscape construction. This paper describes the cold season grass in water and fertilizer consumption, reproductive capacity and management costs and other aspects of the flaw, focusing on analysis in Beijing has been the lack of water resources as one of the primary barriers to economic development in cities, turf varieties should be diversified The direction of development. All kinds of turfgrasses should be adapted to local conditions and configured according to their environmental requirements so as to achieve the effective utilization of resources. Wild ground cover plants are irreplaceable for introducing nature into urban areas and are irreplaceable for urban biodiversity. They should be propagated consciously, Dispatch.
