摘要: 松嫩沙地位于欧亚大陆中纬度巨型沙带的东部边缘, 也是我国沙漠化土地的东缘。其独特的气候条件使沙地的形成与发展、风沙地貌形态及风沙活动规律都具有明显的区域特色。通过对气候因素及其控制下沙地发育的分析, 可以进一步认识该沙地形成演化及现代沙漠化的若干区域性特征

Abstract: Songnen Sandy Land lying in the eastern fringe of great sandy belt in the middle latitude of Eurasia is the eastern edge of desertification-prone land in China. The formation and development of eolian land form and laws of sand movement have regional characteristic predominantly on account of uniqe bioclimatic conditions. This article aims to probe into regional characteristics of sandy land development and modern desertification.

Key words: Songnen Sandy Land Desertification Climatic factors, Eolian landforms, Eolian sand movement
