Xinjiang has been one of the most active region in population movewent among China's 29 provincial level regions since 1949.The paper has re-viewed and analyzed the locus of population gravity center of Xinjiang from 1949to 1986.The dopulation movement of Xinjiang has its own distinguished charac-teristics in different periods.Finally,the paper has revealed the causes of thedopulation movement.

本文对新疆人口重心的移动轨迹进行了描述,分析了影响人口移动的自然经济原因。

This thesis adopts production value of population, GDP, industry, agriculture and the tertiary industry and data of expenditure in recent twenty years in every province, every district ,every city, and figures out the coordinate of gravity center of each years. It quantitatively express developing evolvement of population, GDP, industry, agriculture, the tertiary industry and the consumption center of gravity. On the basis of the result, it analyses the developing evolvement and relation of China population...

This thesis adopts production value of population, GDP, industry, agriculture and the tertiary industry and data of expenditure in recent twenty years in every province, every district ,every city, and figures out the coordinate of gravity center of each years. It quantitatively express developing evolvement of population, GDP, industry, agriculture, the tertiary industry and the consumption center of gravity. On the basis of the result, it analyses the developing evolvement and relation of China population and region discrepancy of economic developing. From the developing evolvement of gravity center we can draw a conclusion: the discrepancies between east and west in China existed twenty years ago, and the population gravity center slowly moves to southwest in China in recent twenty years; on the whole the movements of GDP, industry, the tertiary industry and the consumption gravity centers show to southeast. Against the geometry center in China: on the whole the region discrepancy in China is extended; against the population gravity center: between east and west take on imbalance developing, while between south and north tend to balance; but the change of the agriculture gravity center shows irregularity. The thesis simply analyses driving gene of the developing evolvement of each factor.

采用近 2 0年来中国各省 (市、区 )的人口、GDP、工业、农业、第三产业的产值及消费额数据 ,计算出其各年的重心坐标 ,定量表示出中国近 2 0年来人口、GDP、工业、农业、第三产业及消费重心的动态演化过程。在此基础上分析了中国人口、经济发展、生活水平区域差异的动态变化及其之间的关系 ,以及各要素动态演化的驱动因子。结果表明 :近 2 0年来 ,中国人口重心表现为缓慢地向西南方向移动 ;GDP、工业、第三产业和消费额重心向东南方向移动。与中国几何中心比较 ,区域差异在总体上是扩大了 ;与人口重心相比较 ,东西方向呈不平衡态势发展 ,南北方向则开始趋于平衡 ;而农业重心则表现为无规律性变化。

Using GIS technology,this paper establishes database for graph and database for statistic population,which can meet the study of the minority population gravity center of Gansu.The gravity center positions of the main nationlities and their moving tracks are calculated.This paper also makes thematic map that indicates characteristics of the moving of the population gravity center.And based on it,the rules of the moving of the minority population gravity center are discussed.

利用GIS技术,建立甘肃少数民族人口重心研究的图形数据库和人口统计数据库,计算各主要民族人口重心及其移动轨迹,制作人口重心移动专题图件,并在此基础上对少数民族人口重心移动规律展开讨论。
