What countries are there in Central Asia?

Including Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan and Turkmenistan, with a total area of 4 million square kilometers, accounting for 9. 1% of Asia. 1993 population is about 53 million, accounting for 1.6%. The five Central Asian countries were once allies of the former Soviet Union. After the disintegration of the Soviet Union, it became an independent sovereign state at the beginning of 1992. The region is located in the hinterland of Eurasia, far from the ocean, with a dry climate and widespread deserts. It is irrigated by alpine snow water and river water, oasis agriculture is quite developed, and cotton production is of world significance. Among the mineral resources, oil, natural gas, coal, iron, chromium, copper, lead and zinc are abundant. Economy is a typical type of primary products, that is, exporting cotton, energy, metals and so on. And imported manufactured goods. Per capita GDP is slightly higher than the average number of industries in Asia. Before and after the independence of the five countries, due to the drastic changes in the political and economic environment, industrial and agricultural production fell sharply and is still in the process of recovery. Central Asia is high in the southeast and low in the northwest, which can be roughly divided into three zones: the mountains in the southeast, mainly Kyrgyzstan and Tajikistan, are about 3000 meters above sea level, and the economy is mainly agriculture and animal husbandry; Central hilly areas, including the main areas of Kazakhstan, Uzbekistan and Turkmenistan, have become economically developed areas due to the supply of alpine snow water, guaranteed water sources and rich other resources. Irrigation agriculture in this area is prominent and major cities are concentrated; The western plain is basically a desert, because the water in the high mountain area is consumed by the low mountain area, and this area suffers greatly, and the Aral Sea, the fourth largest lake in the world, is also on the verge of water shortage.
