Abstract
All distinctions in the economic and nature protection policy of the neighboring states are well reflected and shown within trans-boundary river basins. The parts of trans-boundary geosystem of one country can experience an essential negative influence from rash decisions in the field of nature use and nature protection policy of the neighboring state. The Amur River Basin covers the territories of Russia, the Peoples Republic of China, Mongolia and Democratic People’s Republic of Korea and occupies more than 2 million km 2 . The most intensive development of the basin territory has started since the middle of the 19 th century. We compiled two maps of land use in the Amur River basin in the 1930–1940s and in the early 21 st century. Results showed that, negative dynamics is marked for forest lands, meadows, wetlands and mountain tundra. The basic features in the change of land use within national parts of the basin in Russia, China and Mongolia are analyzed. The comparative analysis of land use peculiarities of the countries for the last 70 years has been done.
Highlights
Any country, as a rule, aspires to strictly define and support its own sovereignty by means of its frontiers, and to develop certain cooperation with other countries, especially with its neighbors
An inventory of different materials containing information on land cover/land use statements in the 1930–1940s in the Chinese, Russian, and Mongolian parts of the Amur Basin showed that topographical maps published during the same period were the main source of land use data, and that it was possible to compile the Land Cover Map of the Amur River Basin during the 1930–1940s on their bases [Ganzei and all, 2009]
The Mongolian part of the watershed was characterized through an analysis of topographical maps in the scale of 1:100,000, 1:200,000, and 1:1,000,000 compiled in the USSR in the 1930s–1940s
Summary
As a rule, aspires to strictly define and support its own sovereignty by means of its frontiers, and to develop certain cooperation with other countries, especially with its neighbors. In this process, frontier territories can play a pioneer role. A trans-boundary territory is formed from closely and steadily co-operating frontier territories This transboundary territory often has a common uniform natural and geographical basis that strengthens coherence within transboundary territories, and simultaneously demands for the development of shared approaches to nature management to working out of joint programs of development
