Abstract:

Based on methodology of geo-information sciences, using remote sensing and map data, four maps of oasis distribution covering 1960, 1978, 1990 and 2000 at the northern foot of the Tianshan Mountains are compiled. From 1949 to 1967 the expansion of oasis area is very fast, especially in farmland area where the oasis area was about 0.4 ×104 km2 before 1960 and 1.543 ×104 km2 in 1978. From 1967 to 2000, the dominated urbanization resulted in diminution of farmland area. The urban and construction area was 0.042 ×104 km2 in 1978 and 0.152 ×104 km2 in 2000. This development was mainly because of rapid population growth and economic development. In 1949, population at the northern foot of the Tianshan Mountains was only 39.11 ×104, GDP (Gross Domestic Product) was RMB 11,637.56 ×104 yuan. In 2000, population increased to 479.43 ×104, which was 12.26 times that of 1949, GDP amounted to RMB 6,365,873 ×104 yuan, which was 547 times that of 1949. But the large-scale exploitation to natural resources with population growth and economic development leads to a series of serious eco-environmental problems, for example, about 1/3 of farmland is suffering from soil salinization. Rational utilization of resources and protection of eco-environment will be important approaches.
