Abstract:
The Tsangpo-Brahmaputra River is an important international river. Obtain the information of spatial pattern and change characteristic of Gross Domestic Product (GDP), will help to formulate reasonable international river management policy. However, traditional GDP data take administrative region as a statistical unit, is not convenient to statistic and analysis in international river regions. 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 large GDP. Though the GDP in the ‘South Tibetan region’ and Bhutan is small, but growing fast. Compared to other economical section, the secondary industry accounted a small proportion in GDP, and this result indicated that the industrial development level is not high over the whole basin. In addition, agriculture accounted a large section in GDP, which is the major source of economy, and other section is small.
