人们越来越关注家庭花园对支持生物多样性的价值。虽然这是公认的大黄蜂利用城市绿色空间，这是第一次研究，探讨土地使用和花卉的偏好，英国的七个最常见的大黄蜂在花园和分配种植的食物。2013年6月1日至9月30日，在38个地点进行了公民科学调查。在景观尺度上，熊蜂的丰度和物种丰富度与周围土地利用特征的相关性不显著（均p > 0.05）。草原熊蜂是唯一与周围土地利用相关的物种，与建筑面积、花园和分配呈正相关，与绿地和农业呈负相关。在当地的网站级规模，熊蜂丰度呈负相关，种植蔬菜和水果的面积，并与花卉种植面积呈正相关，虽然相关性不具有统计学意义（分别为p = 0.070和p = 0.051）。大黄蜂物种丰富度与土地利用方式均无相关性（p > 0.05）。所有熊蜂物种与种植蔬菜和水果，裸露的地面和硬铺路面积呈负相关。几种开花植物访问了所有的大黄蜂物种，虽然大黄蜂物种之间的相对偏好不同。结果强调，包括花卉资源的重要性，在花园和分配区域种植的食物，并需要一个马赛克的不同开花植物，以满足不同的花卉偏好表现出的熊蜂物种。
There is increasing interest in the value of domestic gardens for supporting biodiversity. While it is well established that bumblebees exploit urban green spaces, this is the first study to explore the land use and floral preferences of the UK's seven most common bumblebees in gardens and allotments cultivated for food. A citizen science survey was carried out at 38 sites, between 1st June and 30th September 2013. At the landscape scale, bumblebee abundance and species richness was not significantly correlated with surrounding land use characteristics (both p > 0.05). Bombus pratorum was the only species to show correlations with surrounding land use, demonstrating a positive relationship with built areas and gardens and allotments, and a negative correlation with greenspace and agriculture. At the local site-level scale, bumblebee abundance was negatively correlated with areas cultivated for vegetables and fruits, and positively correlated with areas cultivated for flowers, although neither correlation was statistically significant (p = 0.070 and p = 0.051 respectively). Bumblebee species richness was not correlated with either land use (p > 0.05). All bumblebee species were negatively correlated with areas cultivated for vegetables and fruit, bare ground and hard paving. Several flowering plants were visited by all bumblebee species, although relative preferences varied between bumblebee species. Results emphasise the importance of including floral resources within garden and allotment areas cultivated for food, and the need for a mosaic of different flowering plants to cater for varying floral preferences demonstrated by bumblebee species.
