青藏高原地区人类发展水平评估及其演变分析

Human Development Assessment and Evolution Analysis on the Qinghai-Tibet Plateau

通过夜光发展指数(NLDI)、文化多样性和城市位序规模法则3个维度进行分析,评估不同时期青藏高原地区的人类发展水平。研究表明:(1) 21世纪以来,青藏高原地区人类发展水平在逐年提升,但是人类发展水平整体上还处于中等偏下水平,区域内部人类发展水平存在一定的空间差异,东南部夜间灯光强度比较高,人口分布集中;(2)青藏高原民族多样性较高区域主要沿着藏彝走廊和河西走廊延伸和扩展,多元文化交融地区的夜间灯光强度高,人类发展水平总体呈上升趋势;(3)采用位序规模法则分析由夜光强度构建的城市规模,最大城市规模太小仍然是青藏高原地区城镇体系的突出问题。

Through specific analysis of the three dimensions of night light development index(NLDI),cultural diversity and the rank-size rule,the human development level of the Qinghai-Tibet Plateau in different periods is evaluated.The results show that:1)Since the 21st century,human development in the Qinghai-Tibetan Plateau has been improved year by year,but the overall level of human development is still below average level.There are some spatial differences in the level of human development within the region.The night light intensity in the southeast is relatively high,showing the concentrated population distribution.2)The areas with high ethnic diversity in the Qinghai-Tibetan Plateau mainly extend and expand along the Tibetan-Yi Corridor and Hexi Corridor.The night light intensity in the multicultural blending area is high,and the overall level of human development is on the rise.3)The rank-size rule is used to analyze the urban scale constructed by night light intensity.A prominent problem in the urban system of the Qinghai-Tibet Plateau lies is that the maximum urban scale is still too small.
