Climate change and sandy desertification combating in China

The global climate is getting warm. During the past one hundred years, the average temperature over the world has increased by 0.6°C. By the middle of the 21th century, according to the predictions of various global climate models, the average annual temperature will have increased by 1 [similar to] 3°C, the global precipitation increased by 3 % [similar to] 15 %. The predictions of China's future climate variation indicated that by the year of 2050 the temperature in the most part of China will increase by 0.5 [similar to] 1.0°C, but the annual precipitation will decrease to some extent. After 2050, the annual temperature in China will possibly increase by 2 [similar to] 3°C, and the annual precipitation will decrease by 1% [similar to] 7.5%. The general trend for China's climate changing is that it will become warmer and drier, and the northwest of China will be much warmer and drier, comparing with the climate changes in the east. Therefore, in the west development and its processes of ecological establishment and desertfication combating, this kind of change should be fully taken into consideration. Furthermore the suitable strategies and practical countermeasures shall be adopted either in the protection of the existing oases and vegetation coverage, or in the future ecological management and sand industry development.
