内蒙古戈壁盘羊家域、食性、繁殖行为及种群现状研究

According to the habitat selection of the population falling rare and endangered species and the national two levels of protections animals - - Gobi subspecies of Gobi Argali ( Ovis Ammon darwini ), we carry out effects of habitat selection and population quantity factors analysis research, and establish corresponding evaluation system by useing the theory of behavioural ecology with feeding, reproductive behavior, habitat to environmental factors and relations as the breakthrough point, The research involves the content as follow: （1）with the method of microscopic fecal analysis, we study food composition and seasonal changes. （2）The systematic observation and recording of reproductive behavior, it also should establish spectrum of reproductive behavior. （3）the Global Star / GPS collar tracking technique was used to determin home domain and its seasonal variation range. The habitat food, food composition, the local meteorological data, the home range was combined to reproductive behavior ,the deep analysis was given to the relationship around its seasonal variation, feeding, breeding behaviour and environment factors, at last we can get the studies on the feeding habits, reproduction behavior of argali sheep in Gobi implications for habitat selection, we also can give the evaluation of feeding habits, reproduction of home range and reproductive behaviour in Gobi Argali in selection of habitat.So we can judge the existing Gobi Argali subspecies of the survival of the state in Inner Mongolia,, and then it could provide a scientific basis for my area of Argali in Gobi protection strategy formulation and implementation and management measures.

针对种群数量日趋下降的珍稀濒危物种、国家二级保护动物- - 盘羊戈壁亚种（Ovis ammon darwini）的生境选择，运用行为生态学原理，以食性、繁殖行为、栖息地环境因子及相互关系为切入点，开展影响生境选择和种群数量因素的分析研究，并建立相应的评价体系。研究内容涉及：⑴ 运用显微粪便分析法，研究食物组成及季节变化。⑵ 系统观察和记录繁殖行为，建立繁殖行为谱。⑶ 采用Global Star/GPS项圈跟踪技术确定家域及其季节变化范围。将栖息地食物条件、食物组成、当地气象资料、家域和繁殖行为相结合，分析食性及其季节变化、繁殖行为与生存环境因子的相互关系，研究食性、繁殖行为对戈壁盘羊栖息地选择的影响，评价家域、食性、繁殖行为在戈壁盘羊栖息选择中所起的作用，判定内蒙古现存盘羊戈壁亚种的生存状态，进而为我区戈壁盘羊保护对策的制定和管理措施的实施提供科学依据.
