中文摘要
随着旅游产业的迅猛发展,旅游活动对野生动物的影响越来越被管理部门、环保人士以及动物学家所关注,旅游对野生动物的影响已经成为研究热点之一。有关旅游活动对中国大鲵的影响未见研究报道。中国大鲵是我国特有的,有"活化石"之称的国家二级重点保护野生动物。该项目拟以湖南张家界大鲵国家级自然保护区的大鲵为研究对象,采用野外调查与实地监测方法,通过比较分析不同旅游干扰强度下大鲵生境中隐蔽物、水质与饵料生物等因子的变化,探明旅游干扰对大鲵生境的影响;通过比较研究不同旅游干扰强度生境下大鲵种群在分布与密度、年龄结构与性比、行为特征、繁殖周期、繁殖行为与繁殖率等方面的差异,探明生境变化对大鲵种群特征与种群繁殖的影响,解析旅游干扰对大鲵种群的影响机理以及大鲵种群对旅游干扰的响应机制。有关成果将为协调好大鲵资源保护与生态旅游之间的关系提供重要理论依据,丰富旅游干扰对野生动物影响的研究资料。
英文摘要
With the rapid development of tourism, the impacts of tourism disturbance on wildlife have been widely concerned typically by management agencies, environmentalists and zoologists, and it has become one of research hotspots. Chinese giant salamander (Andrias davidianus) is endemic, known as the "living fossil" and listed as a grade II important protection wildlife in China. However, research considering the impacts of tourism on Chinese giant salamander has never been reported. In the project, Chinese giant salamander in Hunan Zhangjiajie Giant Salamander State Reserve will be investigated with field survey and monitoring method. Covert, water quality and and food organism of the habitats in different regions under different intensity of tourism disturbance will be analysed comparatively in order to ascertain the impact of tourism disturbance on habitat. The diversities of distribution, density, age structure, sex ratio, behavior characteristics, reproduction cycle, reproduction behavior and reproduction rate of the populations in these habitats will be studied comparatively in order to ascertain the impacts of altering habitats on the characteristics and reproductions of the populations. The impact mechanisms of tourism disturbance on Chinese giant salamander and the responding mechanisms of the populations under the tourism disturbance will be found. Results from this project will provide important theory evidences for harmonizing the relationship between protection for Chinese giant salamander resources and ecological tourism. They will also enrich the research materials on the influences of tourism disturbance on wildlife.
