| 1 | 河湟谷地藏族和其他主要民族分布的地理环境特征及其生产方式差异显示文摘青藏高原的人群因其对低温、缺氧环境独特的适应性,获得了科学家的广泛关注.但是,相关研究忽视了青藏高原低海拔地区人类的生存环境研究.文章通过地理环境信息提取和方差分析,统计了河湟谷地197个乡镇的藏族和其他主要民族族群的生存环境差异,并探究其与各民族生产方式的关系.统计结果显示,河湟谷地藏族族群生存环境的年均温相对较高.河湟谷地相对温暖的地理环境使得该地区的藏族族群能够从事种植小麦和大麦、饲养牛羊等的生活方式,这与青海省其他高海拔地区藏族族群的生产方式明显不同.同时,由于河湟谷地藏族族群生存的地理环境特征与其他半农半牧族群(回族族群和撒拉族族群)类似,致使其从事类似的生产方式.河湟谷地的农业族群(汉族、土族)选择相对凉爽、湿润的环境促进了农业生产的顺利开展,而生活在河湟谷地内相对温暖、干旱地理环境的半农半牧族群(藏族、回族和撒拉族)必须从事一定程度的牧业活动,以补充农业活动不足带来的食物匮乏.在安多藏区内,各民族族群的生产方式大致与他们的生存环境紧密相关.另一方面,各民族族群相互交流、融合、影响,繁育了多彩的民族文化.本研究进一步证明了在区域尺度下,生存环境差异与生产方式差异有着直接的对应,细化了我们对藏族的人地关系的认识,并进一步开拓以定量方法分析族群分布与地理环境相互关系的研究方向. | 贾鑫 李峯 崔梦淳 程国权 赵阳 丁宏 余柏康 鹿化煜 | 2019 | 中国科学:地球科学2019，49，4： | 5 |
| 2 | Differentiations of geographic distribution and subsistence strategies between Tibetan and other major ethnic groups are determined by the physical environment in Hehuang Valley显示文摘The people of the Tibetan Plateau have received extensive attention from scholars because of their unique adaptability to the low temperature and anoxic environments. However, the Tibetan communities and their habitats in the low-altitude regions of the plateau have rarely been studied in a scientific manner. Based on the extraction of geographic information of 197 towns in the Hehuang Valley and on variance analysis, this study examines the habitats and subsistence strategies of the Tibetans and other major ethnic groups in the low-latitude region of the Tibetan Plateau. Our statistical results show that the annual average temperature of Tibetan habitats in the Hehuang Valley is relatively high. The relatively warm environment of the valley allows the Tibetans in that area to cultivate wheat and barley and raise cattle and sheep—a subsistence strategy significantly different from that of other Tibetans in the high-altitude regions in the Tibetan Plateau. In addition, the Tibetan communities in the Hehuang Valley include similar agri-pastoral ethnic groups (including Hui and Salar), both of which adopt similar subsistence strategies. The agricultural ethnic groups (Han and Tu) live in a relatively cool and humid environment facilitating agricultural production, while the agri-pastoral ethnic groups (Tibetan, Hui, and Salar) inhabit relatively warm and arid environment in the valley. Due to the lack of agricultural activities, agri-pastoral groups must also engage in animal husbandry to supplement their diet. In the Ando Tibetan region, the subsistence strategies of the ethnic groups are closely related to their physical environment.Those ethnic groups communicate among themselves, integrate, and influence each other, resulting in a diversified culture. This study proves that the habitat variation at a regional scale corresponds significantly to the variation of subsistence strategies. Our findings may further refine knowledge about the human-environmental relationships of Tibetans and lead future research towards using quantitative methods to analyse the intersection of physical environment and ethnic groups' distribution. | Xin JIA Harry F.LEE Mengchun CUI Guoquan CHENG Yang ZHAO Hong DING Ricci P.H.YUE Huayu LU | 2019 | Science China Earth Sciences2019，62，2： | 2 |
| 3 | 基于多样性指数的云南省民族人口发展态势分析显示文摘文章基于1990、2000、2010年人口数据对云南省县域尺度的民族多样性指数及其变异指数、民族贡献率对云南省民族人口发展态势作了分析。在民族多样性层面上,云南省具有较高的民族多样性指数,在空间上呈现先由东北部向中部上升再向南、北部上升的趋势,反映了民族人口增长的'东北部-中部-南、北部'差异趋势;基于三个截面数据民族多样性变异指数的分析表明民族多样性指数变化与区域内原本的多样性指数基础有极强的关联,云南省民族多样性在总体上呈上升趋势的同时区域间民族多样性差距呈减小趋势,区域间民族人口差距缩小;基于民族多样性民族贡献率的分析表明汉族对民族多样性的贡献集中于东部、东北部、西部地区以及东南部局部地区。 | 孙俊 武友德 骆华松 潘玉君 杨磊 | 2016 | 南方人口2016，31，6： | 2 |
