The wild camel (Camelus ferus) is a critically endangered large ungulate, surviving in just three distinct populations located in the Taklamakan Desert, China;deserts near Lop Nuur, China;and in China and Mongolia within and adjacent to Mongolia’s Great Gobi Strictly Protected Area (GGSPA). The population surviving in Mongolia remains poorly researched, but as few as 500 individuals may survive, although its distribution has remained relatively constant over the past 30 - 50 years. This study aimed at identifying potentially important environmental factors that influence the distribution of wild camels in Mongolia and predicting seasonal movement. We predicted distribution by season using presence only data and selected environmental predictors, including land surface temperature, normalized difference vegetation indices (NDVI), water sources, vegetation and soil. Model predictions revealed that land surface temperature in summer correlated significantly with wild camel distribution, with camels occurring in cooler areas. Abundance of biomass did not significantly correlate with camel distribution. Camels occurred in areas with intermediate levels of NDVI in most seasons, implying that they may base foraging decisions on forage quantity, not quality. Positive correlations of camel distribution with higher NDVI in summer (P = 0.03) suggests that they may prefer herbaceous species that appear after rainfall. Models indicate distance to water sources may be critical for camel distribution in all seasons. Camel occurrence correlated with areas containing shallow mountain soils in summer. Camels displayed no significant habitat correlations in other seasons, yet ranges differed among all seasons. Camels used a common region in spring, summer and autumn that we believe represents the core of the species’ annual range. Wild camel distribution during winter varied significantly from other seasons. Our modelling led to a predicted distribution range that was consistent with

茶叶原产于中国,后来从蒙古经西伯利亚传入俄罗斯。现在,俄罗斯人已是一日不可无茶,喝茶成了俄罗斯全民族的习惯,并在历时几百年的饮过程中,形成了独特的茶文化。在世界上喜欢喝茶的民族不少,但俄罗斯人在喝茶上却有独特之处,在茶炊方面有着独特表现,茶炊本是一种烧开水的金属器皿,但在俄罗斯,茶炊却成了民族传统文化中最具特色的组成部分,是有别于其他民族饮茶风俗的重要标志之一。在现代俄罗斯人的家庭生活中仍离不开茶炊,只是人们更习惯于使用电茶炊。人们用瓷茶壶泡茶叶,在现代俄罗斯的城市家庭中流行趋势是,用茶壶代替了茶炊,茶炊更多时候只起装饰品、工艺品的作用。但每逢隆重的节日,现代俄罗斯人一定会把茶炊摆上餐桌,家人、亲朋好友则围坐在茶炊旁饮茶。根据比较,中俄茶文化之间的差异性也是很多的。具体表现在:历史发展、茶的种类、饮茶的方式、茶具等方面。这些差异性丰富了茶文化的形式。共同点是中俄文化交流达到共识的前提,也是继续加强双方茶文化交流的重要基础。而差异性决定了双方相互学习、相互借鉴、相互进步的必要性。本论文的选题意义可以从五个方面进行理解。第一,以对历史包括历史源流和史料方面和俄罗斯茶炊出现和俄罗斯茶文化演变从17世纪到今天。第二,茶炊在不同的国家。第三,对茶炊设计的特点包括茶炊种类,茶炊风格和构造,茶炊用什么材料来生产方式全面的分析和研究。第四,工厂制造茶炊。第五,茶炊装饰图案的壁画和手绘。
