西藏流浪狗的危害和防控

Damage and control of free-ranging dogs in Tibet

流浪狗是指由于饲养者无意丢失或有意遗弃,而逐渐形成的流浪于各类环境中的野生或半野生的犬类及其后代。由于历史、文化等方面的原因,西藏的流浪狗数量日益增加,分析了流浪狗携带病毒、细菌和寄生虫、伤害畜禽和人、威胁野生动物生存、影响生态平衡和加重环境负荷等5个方面的危害,并结合西藏实际提出了加强普查调研、实施种群控制、增加科研投入、加强宣教立法和因时因地重点保护等防控管理的建议。

Feral or free ranging dogs are wild or semi-wild dogs and their offspring who wander in variable types of environments due to the unintentional loss or deliberate abandonment of their hosts.Due to historical and cultural reasons,the population of feral dogs in Tibet keeps increasing.In this paper,we analyzed the negative effects of feral dogs on the natural eco-systems,including carrying and spreading viruses,bacteria and parasites,injuring livestock and poultry as well as humans,threatening the survival of wild animals,affecting ecological balance and increasing the environmental pressures.According to the actual situation in Tibet,we made prevention and control suggestions as following:strengthening census and investigation,implementing population control,increasing investment in scientific research,strengthening social education and legislation,and protecting local wildlife adjusted to time and location.
