里山是日本传统的土地管理制度，强调人与环境之间和谐关系的重要性。自20世纪60年代末以来，它一直处于废弃和破坏状态。2000年，日本政府启动了一项新的环境政策，鼓励在生物多样性保护区使用里山。在开始积极的修复工作之前，需要对里山系统的潜力进行评估。为了评估这种潜力，2003年6月至10月进行了一项研究，重点是在一个小的废弃的里山梯田野生蜜蜂的觅食生态。共采集到9科35种372只蜜蜂，其中以群居蜂（中华蜜蜂和熊蜂）2种和独居蜂（日本毛舌蜂和欧黑毛舌蜂）2种为主。野蜂的觅食活动受殖民地的食物需求量和孤蜂活动时间的影响。在这项研究中，大多数野生蜜蜂表现出强烈的偏好，丰富的开花植物物种，产生了大量的花朵（牛膝和何首乌）。结果表明，一个废弃的里山系统是一个有利于授粉蜜蜂的农业系统。需要仔细和有计划的恢复实践来增加觅食资源的多样性、微环境的多样性和野蜂的潜在筑巢区，以提高里山系统支持更多样和丰富的野蜂种群的能力。
Satoyama is a traditional land management system in Japan that emphasizes the importance of a harmonious relationship between humans and their environment. It has been in a state of abandonment and destruction since the late 1960s. In 2000, the Japanese government initiated a new environment policy encouraging the use of Satoyama in biodiversity reservation areas. Before the initiation of active restoration works, an assessment of the potential of the Satoyama system is needed. To assess this potential, a study that focused on the foraging ecology of wild bees in a small abandoned Satoyama terraced paddy was carried out from June to October 2003. A total of 372 foraging bees belonging to 35 species in nine families was collected: two species of social bee (Apis cerana and Bombus diversus) and two of solitary bee (Lasioglossum japonicum and Lasioglossum ohei) dominated. The foraging activities of wild bees were highly influenced by the requirement of food for the colony and the active time of solitary bees. In the study, most wild bees showed a strong preference for abundant flowering plant species that produced a large number of flowers (Achyranthes japonica and Polygonum thunbergii). The results showed that an abandoned Satoyama system was an agricultural system that benefited pollinating bees. Careful and planned restoration practices to increase the diversity of foraging resources, microenvironment diversity and potential nesting areas for wild bees are needed to improve the ability of the Satoyama system to support more diverse and abundant wild bee populations.
