摘要在许多非洲国家，非法猎杀丛林肉已经成为野生动物管理人员面临的一个严重问题。我们调查了坦桑尼亚塞伦盖蒂国家公园周围人们肉类和鱼类消费的空间和时间模式，以更好地了解狩猎和消费之间的联系。2006年3月至12月，我们沿着从公园边界到80公里外的坡度对5个村庄的150户家庭进行了研究。此外，在紧邻三个村庄地区的国家公园内，每月监测两个平行的10公里横断面，以调查家庭肉类消费与迁徙食草动物涌入之间的关系。我们发现，离公园边界最近的村庄肉粉数量较多，并且在公园边界30公里以内的所有村庄，随着迁徙食草动物的季节性涌入，每户每周的肉粉数量都有所增加。肉类消费与家庭收入无关，除了最偏远的村庄，那里有正相关。随着迁徙食草动物的涌入，公园附近村庄的鱼粉数量减少。我们建议对维多利亚湖的鱼类捕捞和塞伦盖蒂国家公园周围的野生动物保护进行协调管理，以实施对这两种不同生态来源的动物蛋白质的可持续管理。
Abstract Illegal bushmeat hunting has become a serious problem for wildlife managers in many African countries. We investigated the spatial and temporal pattern in meat and fish consumption by people surrounding the Serengeti National Park, Tanzania, to understand better the links between hunting and consumption. We studied 150 households in five villages during March–December 2006 along a gradient from the Park boundary to 80 km away. In addition, two parallel 10 km transects were monitored monthly in areas within the National Park immediately adjoining three village areas to investigate the relationship between household meat consumption and the influx of migratory herbivores. We found that the number of meat meals was higher in the villages closest to the Park boundary and the weekly number of meat meals per household in all villages within 30 km of the Park boundary increased with the seasonal influx of migratory herbivores. Meat consumption was unrelated to household income except in the most distant village where there was a positive correlation. The number of fish meals in the villages closest to the Park decreased with the influx of migratory herbivores. We recommend a coordinated management of fish harvesting from Lake Victoria and wildlife conservation around the Serengeti National Park to implement sustainable management of these two ecologically different sources of animal protein.
