横断山区人类动态与野生动物灭绝关系的研究-以黑白仰鼻猴为例-丁伟

日期:2016-10-17|来源:

  通过查阅古籍和化石资料,了解近四百年来,随着高产作物物种(玉米和马铃薯为例)的引入,在人口和资源利用模式动态变化压力下大型野生动物(黑白仰鼻猴)分布区不断退缩和灭绝机制,利用 GOOGLE ERATH 3D 可视化系统、实地访谈和有关社区资料,以及上世纪 50年代以来的勘测资料和遥感图片等多种手段来获取人口的迅速增长对森林生态系统和濒动物的长期影响和相互效应方面的数据。引入可用有效生境这个新概念对处于灭绝漩涡的分布区最南缘龙马山种群进行定量的实地研究,探讨现存黑白仰鼻猴种群对不同类型人类干扰行为响应和可用有效生境状况。从历史已灭绝种群着手,真实还原近期(上世纪 50 年代以来)已灭绝种群(凤庆和天池种群)灭绝过程的和灭绝模式,得出人类动态压力下黑白仰鼻猴种群灭绝机制和模型,并对其普适性范围作出检验,对多角度探讨黑白仰鼻猴这种大型旗舰物种的濒危机制和制定更为有针对的保护政策有很大借鉴作用。

By looking at the ancient literature and fossil data,in the past four centuries, with the high-yielding crop species (maize and potato, for example) have begun to grow in China, the distribution reduction and extinction mechanism of large wild animals (black and white snub-nosed monkey, Rhinopithecus bieti) caused by the dynamic changes under the pressure of population and resource use patterns, In addition, the google earth 3D visualization system, field interviews and community information, geological survey data, remote sensing images and other means used to obtain the data of the long-term and mutual effect of rapid population growth on forest ecosystems and endangered animals. With the introduction of the available effective habitat, this new concept is used in the quantitative field research on the southernmost edge of the population. We investigate the behavior response of the existing black-and-white snub-nosed monkey population for different types of human disturbance and availability of effective habitat conditions. According to the data of the extinct populations(since 1950),we will trying restore and Simulate the extinction process and extinction pattern of Fengqing and the Tianchi population, explaining the way how the human dynamic pressure lead to the extinction mechanisms and pattern. After test its scope of application, we believe that the will be of great help for the conservation of the black and white snub-nosed monkey.
