近期中国省际经济社会要素流动的空间特征

本文运用GIS空间分析和图形技术 ,就中国省 (区 )际人口迁移、铁路客流、航空客流、铁路货流、信件流等经济社会要素流动的空间特征进行综合分析。结果表明 :地区经济水平对要素流的形成与分布影响较大 ,京津唐、沪苏浙和广东构成了要素流的三大核心 ;要素流呈现为 4种基本空间型态和两类空间模式 ;各要素流的空间分布很不均衡 ,流量重心大幅偏离我国国土几何重心 ,但与人口和经济分布重心吻合度较高。

Spatial characteristics of the recent inter-provincial flow of social-economic elements in china

This paper reveals spatial characteristics of the recent inter provincial(municipal,regional) flow of social economic elements in China. Firstly, thepaper reviewsthe studies on the trans regional flow of social economic elements in China Then, based on the survey data,it conducts a comprehensive analysis of the spatial characteristics of the productive element flow such as the inter provincial migration, passenger railway flow, airborne passenger flow,railroad freight flow and information flow, by adopting GIS spatial analysis and visualization techniques. The spatial distribution of the inter provincial flow is influencedevidently by the provincial economic status and the pattern of inter provincial economic relations The eastern China shows its great importance on the distribution of the inter provincial flow The three economic heartlands of China, Jing Jin Tang (Beijing, Tianjin, Hebei), Hu Su Zhe (Shanghai, Jiangsu, Zhejiang) and Guangdong also act as the main centers of inter provincial flow The gravity centers of all the inter provincial flows are relatively close to the population and economic centers of China, but deviate far more from the geometric center of the territory This means the spatial distribution of inter provincial flow is basically consistent with the socialand economic situationof China Further, the paper concludes the spatialdistribution of the flow of social economic elements as four fundamental patterns, which are tested in each type of the flow and two holistic styles are deduced
