摘要： 本文论述了中国草原带的分布特点及其生态系统的服务价值;指出中国草原带对沙尘暴起沙源地的阻挡和覆盖作用;从不同时间尺度论述了沙尘暴的形成原因;提出沙尘暴的净化作用、中和作用、提供植物矿质营养和太阳伞效应等四方面的生态效益;阐述了如何全面认识沙尘暴,预测沙尘暴的出现趋势,为沙尘暴防治提供参考依据。

关键词: 中国草原带, 沙尘暴, 生态效益

Abstract: The paper reviews the distribution characteristics and the service value of different ecosystems of China's steppe zone,and analyzes the steppe zone's function as ground cover for resisting sand-dust storms.Based on the different time scale,the paper discusses the fomation of sand-dust storms and trys to foretell their developing tendencies years before they actually burst while acknowledging their ecological benefits,as they can clean the atmosphere of some toxic matters,neutralize the acid deposition,provide mineral fertilizer for plants,and offer a parasol effect.The paper also gives some reference data for the understanding and control of sand-dust storms.

Key words: Chinese steppe zone, Sand-dust storm, Ecological benefit
