Characteristics of Oasis before and after the Ecology Water Transportation in Lower Reaches of the Tarim River
摘要
Abstract
According to the classification of artificial and natural oasis proposed by Fan Zili et al, the change law and proportion of artificial and natural oases in Lower Reaches of the Tarim River during 1990-2000 and 2000-2010 were studied on the basis of the previous studies and the remote sensing images data,and the appropriate proportion between artificial and natural oasis was discussed.The mainly results as follows:During 1990 to 2010,artificial oasis is expanded at a rate of 19.09 km2/a,while natural oasis is shrank at a rate of 13.02 km2/a. Before the ecology water transportation,the high-cover grassland area,lake area and reservoir area deduced by 43.91%, 100% and 45.28%,and the cultivated land increased by 12.31%,respectively. After the ecology water transportation,high-coverer grassland area only decreased by 6.79%,the reservoir area increased by 392.44% and cultivated land increased by 30.37%. The total area of oases(the artificial's+ natural's)basically remain unchanged,and the changes mainly occurred in the reciprocal transformation between artificial and natural oases. The natural oasis was gradually replaced by artificial oases in recent 20 years,and 1 unit area of artificial oasis increased,1.1 unit area of natural oasis decreased.关键词
