摘要
山地是熊蜂最重要的栖息地，而熊蜂是山地环境质量的重要指示生物，被广泛应用于指示人类活动对生态质量的影响。2002～2007年在四川西部4种生境中随机选择地点采集野生熊蜂，记录熊蜂物种及其访花植物，分析熊蜂对蜜粉源植物选择偏好。共采集熊蜂3048只，属于15个亚属的47种。分析表明，熊蜂偏好选择一种或少数几种蜜粉源植物，同一种熊蜂在不同生境中对蜜粉源植物选择偏好不同，同一种熊蜂在同一生境中可偏好选择多种蜜粉源植物。最后讨论了熊蜂对蜜粉源植物选择偏好的生态意义。
Mountains are the main habitats of bumblebees. Bumblebees are good indicators in assessment of environmental health and have been used as an indicator to assess human impacts on agricultural ecosystem. Bumblebees and their food plants were randomly sampled in four types of grasslands in west Sichuan from 2002 - 2007 in order to study bumblebees＇ preference for food plants. A total of 3 048 bumblebees were recorded, belonging to 47 species in 15 subgenera. Bumblebees showed preference to a few food plants and they showed preference to different food plants in different habitats. They also showed preference to several species of food plants in one habitat. The food plant preference has ecological importance, which deserves further study.
