The importance of human-dominated green spaces for biodiversity support is increasing. With the popularity of rooftop farms to grow healthy and local food, can rooftop farms provide wildlife habitats? This study conducted a year-round survey on eight rooftop farms to reveal (1) plant and faunal species composition and diversity of the rooftop farms, (2) variations in plant and faunal species composition by site and the four seasons, (3) effects of site and surrounding characteristics on faunal species composition and diversity, and (4) examine whether higher taxa was adequate in indicating species-level faunal species composition on rooftop farms. This study used visual observation and pitfall trap methods to conduct a faunal species survey twice a season; and recorded plant species and their blooming status in each survey. Arthropods were the survey target, and Molluscs found in the cultivation area were also recorded. The season averages in plant species number and blooming species were 30–50% and 20–30% of the total number of plant species in a year. Generalist species dominated rooftop farms. Site and seasons significantly affected faunal species composition and diversity. The site characteristics significantly affected the rooftop farms' faunal species composition and diversity, but the surrounding characteristics almost had no effects. The larger rooftop area led to a larger cultivation area, resulting in more plant and blooming species and attracting more faunal species. Humans managed the vegetation on the rooftop farms might form a distinct habitat. Family-level performed well as a surrogate in indicating faunal species-level composition on rooftop farms.

以人类为主导的绿色空间对生物多样性支持的重要性正在增加。随着屋顶农场种植健康和当地食物的普及，屋顶农场能否提供野生动物栖息地？本研究对八个屋顶农场进行了全年调查，以揭示 (1) 屋顶农场的动植物物种组成和多样性，(2) 不同地点和四个季节的动植物物种组成变化，(3) 影响关于动物物种组成和多样性的场地和周围特征，以及（4）检查更高的分类群是否足以指示屋顶农场的物种级动物物种组成。本研究采用目视观察和陷阱法，每季进行两次动物物种调查；并在每次调查中记录植物种类及其开花状况。调查对象为节肢动物，还记录了养殖区发现的软体动物。植物物种数量和开花物种的季节平均值分别占一年植物物种总数的30-50%和20-30%。通才物种主导了屋顶农场。地点和季节显着影响动物物种组成和多样性。场地特征显着影响屋顶农场的动物物种组成和多样性，但周边特征几乎没有影响。更大的屋顶面积导致更大的种植面积，导致更多的植物和开花的物种，并吸引更多的动物物种。人类管理屋顶农场的植被可能会形成一个独特的栖息地。
