The current crisis of worldwide agglomeration and economic, spatial, and ownership factors, among others, mean that there is usually a shortage of new green areas, which are socially very beneficial. Therefore, various brownfields or degraded lands along public transport routes, e.g., tram lanes, are effectively transformed for this purpose. The significant potential of tram systems is that they can became a backbone of green corridors across the city. This case study of the Warsaw tram system (total length over 300 km of single tracks in service in 2019) enables us to simulate the potential growth of a biologically active area connected with an increasing share of greenery around tram lanes in Warsaw. Experience allows the authors to present the types of greenery systems based on existing and future tram corridors best suited for this city. The suggested usage of tram lanes as green corridors is in line with the generally-accepted concept of urban green infrastructure. Therefore, the aim of the authors is to present in a condensed fashion their views on a very important issue within the program of the revitalization of the Warsaw landscape by converting where possible the existing tram lines, as well as planning new ones according to the “green point of view”.

电车网络在振兴华沙景观中的潜力

当前全球范围内的集聚危机以及经济，空间和所有权因素等因素意味着，通常缺乏新的绿色区域，这在社会上是非常有益的。因此，为此目的，有效地改造了公共交通路线（如电车道）上的各种棕地或退化土地。电车系统的巨大潜力在于它们可以成为整个城市绿色走廊的骨干。这项对华沙电车系统的案例研究（2019年投入运营的单线总长度超过300公里）使我们能够模拟生物活跃区域的潜在增长，并与华沙电车车道周围越来越多的绿色植物相关联。经验使作者能够根据最适合该城市的现有和将来的电车走廊展示绿化系统的类型。建议将电车车道用作绿色走廊，这与普遍接受的城市绿色基础设施概念相符。因此，作者的目的是通过振兴现有的有轨电车路线，并根据“绿色观点”。
