摘要
沙漠化(Aeolian desertification)是干旱、半干旱及部分半湿润地区由于人地关系不相协调所造成的以风沙活动为主要标志的土地退化。沙漠化科学是将风沙活动为主导灾害现象的区域作为完整的生态蛳环境蛳社会蛳经济综合体,开展沙漠化过程及其防治研究的科学。本文介绍了国内外沙漠化研究的进展,结合我国在该领域存在的问题,提出了近期沙漠化科学研究的主导学术思路、研究方法和研究重点,以更好地服务于西部大开发战略的进一步实施过程中对北方沙漠化防治、区域社会经济和谐发展和生态环境的修复。
Aeolian desertification is land degradation mainly characterized by wind erosion in arid, semiarid and sub-humid regions resulting from the excessive human activities on natural resources. The Aeolian Desertification Science is the science which studies aeolian desertification processes, taking the areas where sand-blown activities are the dominant disaster phenomena as the whole Ecology-Environment-Society-Economy complex. In this paper the author firstly introduces the advances on aeolian desertification research both at home and abroad; then combining the existing problem in this research field in China, brings forward the leading academic train of thought, research methods and research priorities for the aeolian desertification research in the near future, with a view to better serve the further implementation of the grand western development program of China, i.e., more effectively preventing and controlling aeolian desertification, promoting the harmonious development of regional socio-economy, and restoring the ecological environment to a greater extent, and so on.
