摘    要:东北平原西部沙地位于欧亚大陆中纬度巨型沙带的东部边缘 ,为我国荒漠化土地的东缘。随着经济的发展 ,生态环境遭到严重破坏 ,荒漠化景观日益明显 ,前景令人堪忧。气候因素是荒漠化发展的一个基本因素 ,东北平原西部沙地是我国北方气候条件最好的沙区 ,但目前对于区域荒漠化驱动因子的气候因素影响方面的研究未开展系统的工作。论文系统分析了东北平原西部沙地影响荒漠化的现代气候因素特点 ,探讨了在较好气候条件下气候变异、人类活动与荒漠化之间的关系 ,并根据气候发展趋势预测了未来在自然因素作用下沙地的可能发展趋势。

关 键 词:东北平原  西部沙地  荒漠化  气候变异  人类活动  发展趋势

Abstract:West sandy land of Northeast China Plain lies in the eastern fringe of huge sandy belt of middle latitude in Eurasia Continent which is also the eastern fringe of desertified land with best bio climatic conditions in China.With the development of economy and the deterioration of eco environment,desertified landscape becomes increasingly obvious and is very anxious for us.Climatic factor is a fundamental factor for desertification development,the climate in west sandy land of Northeast China Plain is the best among the sandy lands in northern China.So far no systematic research work on climatic change and desertification has been carried out in this region.This paper analyzes the modern climatic features that affect desertification in west sandy land of Northeast China Plain,explores the relations between climatic variations,human activities and desertification,and predicts the possible trend of desertification under the effect of natural factors according to climate development trend in the future, providing the basis for desertification control.
Keywords:west sandy land  Northeast China Plain  desertification  climatic variation  human activities  developmental trend
