云南省各州市少数民族人口分布格局研究

Minority Population Distribution Pattern of the Prefectures of Yunnan Province

利用全国第六次人口普查和云南省统计年鉴数据,以云南省16州市为研究区域,同时结合Arcview软件,运用定量分析方法对少数民族基尼系数、少数民族人口比重、少数民族成分构成指数、离散度进行研究。研究表明:在水平分布方面,各州市少数民族人口数量差异明显;各州市少数民族人口水平分布格局差异明显;少数民族分布聚集程度较高的区域呈L型集中分布,主要集中分布在澜沧江流域、红河流域。在垂直分布方面,地形起伏度与少数民族人口数量呈一定的负相关性。人口比重和地形起伏度较高的区域,少数民族分布比较单一,而人口比重和地形起伏度较低的区域,少数民族分布比较复杂。地形起伏度越高,少数民族成分构成指数越大,反之,地形起伏度越低,少数民族成分构成指数越小。

Using the sixth national population census and the statistical yearbook data of Yunnan province, with 16 cities in Yunnan province as the study area, and combining Arcview software, the thesis employs quantitative analysis to conduct research on Gini coefficient of ethnic minorities, ethnic minority population, ethnic composition index, and the discrete degree. Research shows that ： in terms of horizontal dis- tribution, each state minority population difference is obvious. Each state has clear difference in level of minority population distribution ; the high aggregation extent for the distribution of ethnic minorities takes on L form, which mainly distributed in Lancang River, Honghe River. In terms of vertical distribution： topo- graphical relief and minority population has certain negative correlation. In areas of higher population and relief degree, ethnic minority distribution is unitary, while the distribution is more complex in areas of lower population and relief degree. The higher relief degree is, the greater the ethnic composition index is, and vice versa.
