欧洲的城市当局面临着城市居民对分配花园日益增长的需求，但空置的城市土壤往往稀缺和/或受到过去工业活动的污染。因此，地方当局的一个可能的解决办法是促进屋顶园艺。然而，关于某些形式的屋顶城市农业（称为Z农业）的技术信息很少。2012年，在巴黎（法国）进行了一项试点实验。简单而廉价的屋顶园艺系统在屋顶上进行了测试，仅使用当地城市有机废物作为作物基质，以促进城市新陈代谢。测定了种植基质和食用蔬菜的产量水平和重金属含量。现有的结果表明：（一）高水平的作物生产与有限的投入相比，土地专业园艺，（二）低水平的重金属污染物在作物的可食用部分，特别是镉和铅相对于欧盟规范的蔬菜和（三）积极的影响，产量组织层基板和提高生物活性，通过接种。这些令人鼓舞的结果使我们认为屋顶园艺是可行的，似乎有很大的潜力，以提高城市的弹性。然而，有必要更准确地确定可以使用的屋顶类型，并更充分地评估低污染水平的一般结果以及这些种植系统的全球可持续性。关键词：都市农业，都市农业，有机废弃物，绿色屋顶，蔬菜文章数据首次收到：2015年1月15日|最后修订日期：2015年5月10日接受日期：2015年5月11日|在线发布：2015年5月20日URN：nbn：de：hebis：34-2015031947776
Urban authorities in Europe are confronted with increasing demands by urban dwellers for allotment gardens, but vacant urban soil tends to be scarce and/or polluted by past industrial activities. A possible solution for local authorities could therefore be to promote rooftop gardening. However little technical information exists on certain forms of rooftop urban agriculture, called Z-Farming. In 2012, a pilot experiment was run in Paris (France). Simple and cheap systems of rooftop gardening were tested on a rooftop using as crop substrates only local urban organic waste so as to contribute to the urban metabolism. Production levels and heavy metal contents in cropping substrates and edible vegetables were measured. Available results show (i) high levels of crop production with limited inputs compared to land professional gardening, (ii) low levels of heavy metal pollutants in the edible parts of the crops, especially for Cd and Pb with respect to EU norms for vegetables and (iii) positive influence on yields on organizing the substrate in layers and enhancing the biological activity through earthworm inoculation. These encouraging results allow us to consider that rooftop gardening is feasible and seem to have a great potential to improve urban resiliency. It will nevertheless be necessary to identify more precisely the types of roof that can be used and to assess more fully the generic result of the low level of pollution, as well as the global sustainability of these cropping systems.
