| 摘 要： | 全球气候正在变暖 .过去 10 0多年中 ,全球平均气温上升了 0 6℃ .根据全球多种气候模式的预测 ,到 2 1世纪中期 ,全球年平均气温将要升高 1～ 3℃ ,全球降水量增加 3 %～ 15 % .对我国未来气候变化的预测 ,到 2 0 5 0年我国大部分地区将增暖 0 5～ 1 0℃ ,年降水量有所减少 ,2 0 5 0年以后年均温可能增加 2～ 3℃ ,降水量减少 1%～7 5 % ,未来我国气候变化趋势呈变暖变干 ,我国西北广大地区与东部相比将更暖更干 .因此 ,在西部大开发 ,从事生态建设和防沙治沙过程中 ,要充分考虑未来我国气候的这种变化 ,做出具体的战略部署 ,采取强有力的战术措施 ,在立足于保护好现有绿洲和植被的前提下 ,进一步搞好西部生态建设 ,促进防沙治沙和沙产业的发展

| Abstract: | The global climate is getting warm.During the past one hundred years,the average temperature over the world has increased by 0.6℃.By the middle of the 21th century,according to the predictions of various global climate models,the average annual temperature will have increased by 1～3℃,the global precipitation increased by 3%～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 0.5～1.0℃,but the annual precipitation will decrease to some extent.After 2050,the annual temperature in China will possibly increase by 2～3℃,and the annual precipitation will decrease by 1%～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. |
