Based on the research carried out by the author for many years, the opinion about the desertization of arid, semi-arid and some semi-humid areas in the north zone of China is given in paper.
There is mounting evidence that increasing amount of man-induced atmospheric carbon dioxide may lead to significant change in global climate during next century.
Scholars have adopted different focii for the analysis of industrial change. This sandy at-tempts to combine a regional approach with the approach adopted by geography of enterprise in order to overcome the limitations of usinb either approach alone.
In this paper, the authors first discussed the strategical significance of King George 1sland area according to its influence of geographical environment, especially climate and resources on aviation, navigation and expedition.
As a problem of the degredation of ecotope in the arid areas of inland, the salinization of water quality is as serious as the desertification and salinization of soil. Before 1958, Tarim River was a freshwater river with the general minieralization rate lower than 1 g/1.
Climate is one of the important research subject nowdays. In order to predict the change of climate henceforth, the recovery and rebuilding of ancient climate is a quite important re-search task.
