中文摘要	中亚是盐尘暴高发地区之一，由自然因素和人文因素引起的沙质和盐质荒漠广泛分布。据初步估计，平均每年从干涸的咸海盆地通过空气输送出的盐尘为0.510^6t到2010^6-30*10^6t不等。这些盐尘的沉降受地形、风力和距源地的距离的影响。中亚地区盐尘暴的季节性和频率受降雨的影响很大。盐尘不仅影响气候，还会给人们的健康与经济活动带来不利影响。通过对过去近40年研究工作的总结和分析，对中亚地区盐尘暴的现状及其未来变化有了基本的认识：（1）盐尘的产生、搬运和沉积在中亚地区是目前的普遍现象，特别是在咸海区域。（2）过去近40年的咸海危机证明：适当的自然保护需要很长的时间和大量的资本投入。（3）要缓和目前的现状并创建一个稳定的、健康的环境，在实施各项计划中需要综合考虑社会、经济与生态问题。
英文摘要	Central Asia is one of the regions with a high frequency of dust and salt storms. It is characterized by the presence of the vast areas of sandy and solonchak deserts of natural and anthropogenic origin. The preliminary estimations showed the average transfer of the salt and dust aerosols from the dried bottom of the Aral Sea varies between 0. 5 * 10~6 t to 20 x 10~6 ~ 30 * 10~6 t. Much of the dust has a high salt concentration. Sedimentation of the salt-dust aerosols to a certain extent depends on the orography of the landscape, wind intensity, distance from the source of the blowout etc. The precipitation influences significantly the seasonally and frequency of dust storms in Central Asia. The salty dust affects not only climate and landscapes, but also the health and economic activity of the population.This paper analysed the research work conducted over the past 30 ~ 40 years, outlined the present situation, and gave some prediction of the likely future of the region. Key points include that ( 1) Removal, transportation and deposition of the salty dust are one of the most negative phenomena experienced at present in Central Asia, especially in the Aral Sea region. (2) The Aral Sea crisis experienced during the past 30 ~ 40 years, has led to the realization that the implementation of adequate nature conservation measures requires a long period of time and significant capital investments. (3 ) There are measures that can be taken to ameliorate the situation and create a more stable and healthy environment but the task is urgent and needs to be approached in a holistic way that deals with socio-economic as well as ecological problems.
