西藏藏羚种群数量动态研究

本研究通过查阅文献、书籍和历史资料对100多年来藏羚种群数量及分布作分析和展示,为探讨西藏藏羚种群变化规律,提供科学理论依据。结果表明:藏羚种群数量在时间尺度和局部空间格局上均呈现出差异;在长期观测中,藏羚整体种群数量表现出先降低再升高的规律,体现出西藏自然保护区的建立、法律健全和全民生态保护意识提高等措施对藏羚保护的重要性。此外,种群密度也在不同空间格局上有所不同,这突出了藏羚对栖息地的选择偏好活动范围之广。从影响其种群数量的驱动因素来看,人为影响是藏羚数量变化的主要因素,为保护藏羚,应加强人与自然和谐共处。

Population Dynamics of pantholops hodgsonii in Tibetan Autonomous Region

In this study,the population and distribution of Pantholops hodgsonii in the past 100 years were analyzed and displayed by consulting literature,books and historical materials,which provided a scientific theoretical basis for discussing the change law of P.hodgsonii population in Tibet.The results showed that the population size of P.hodgsonii was different in both time scale and local spatial pattern.During the long-term observation,the overall population size decreased first and then increased,which reflected the importance of the establishment of nature reserves,the perfection of laws and the enhancement of ecological protection awareness of the whole people.In addition,population density also varies in different spatial patterns,which highlights the choice of habitat and even the wide range of P.hodgsonii.Overall,human influence is the main factor for the population change of P.hodgsonii.In order to protect P.hodgsonii,harmony between human and nature should be strengthened.
