| 摘 要： | 近年来人们对全球气候变化的问题尤为关注,因为,如今气候变化不仅仅是科学问题、环境问题,还是一个国际政治问题、经济问题,事关社会的长远发展.本研究以沙尘暴为切入点,在前人研究的基础上,总结了近年来沙尘暴及沙尘天气发生频率的变化趋势及其地域性差异,并进一步讨论了沙尘暴发生频率变化趋势与温度变化的响应机制,认为沙尘暴发生频率变化与气温变化呈负相关关系.近年来中国沙尘暴发生频率呈整体下降趋势,表明近年来中国气温有整体升高的趋势,这可能是全球变冷大趋势中的次级波动.

| Abstract: | Receiving growing concerns in recent years,global climate change has grown from a scientific and environmental issue into an international political issue,which will be related to the long-term developments of international community.This paper summarizes trends and regional differences of dust storm frequency in recent China,and discusses responding mechanism of the frequency to global climate change.The study finds a negative correlation between the dust storm frequency in China and the change of global temperature.Overall,the frequency of dust storms in China decreases in recent years,going with an increasing trend of temperature in China,which is possibly one of the secondary fluctuations in the general trend of global cooling. |
