雅鲁藏布江-布拉马普特拉河流域GDP数据空间化估算与分析

Estimation and analysis of spatialized gross domestic product data in Tsangpo-Brahmaputra River basin

雅鲁藏布江-布拉马普特拉河是重要的国际河流,掌握该流域GDP数据空间分布状况及其变化信息,有助于制定合理的国际河流管理政策,维护区域稳定和发展。传统的GDP数据以行政区为统计单元,不便于国际河流相关信息的统计分析。以土地利用数据为基础,实现了雅江流域GDP数据空间化估算。结果表明,印度、孟加拉国在GDP总量方面均有一定优势,不丹和藏南的总量相对较小,但是增速最快,所有区域中第二产业所占比重均不大,说明全流域整体工业发展水平不高,而藏南主要经济来源是农业,其它产业比重较小。

The Tsangpo-Brahmaputra River is an important international river.To obtain the spatial distribution and variation information of the gross domestic product（GDP）data in this basin is conducive to formulating reasonable international river management policies.However,traditional GDP data,taking administrative region as a statistical unit,is not suitable for statistical analysis of international rivers.Based on the land cover data,we estimated the spatial distribution data of GDP in Tsangpo-Brahmaputra River basin.In Tsangpo-Brahmaputra River basin,India and Bangladesh have a large GDP,while the′South Tibetan region′and Bhutan have a relatively small but the fastest-growing GDP.The proportion of the secondary industry is small in all the regions,indicating that the industrial development level is not high throughout the basin.Agriculture is the primary source of income in South Tibet,while other industries only occupy a small proportion.
