中文摘要	土地沙漠化灾害危险性评价对防治沙漠化灾害具有重要的科学与实践价值。通过提出沙漠化灾害危险性评价的理论框架和方法,构建多指标综合模型,对中国北方土地沙漠化灾害危险性进行了评价。结论如下: ①中国北方沙漠化灾害危险性以轻度、较轻、中度和较重为主。呈由沿海向内陆、由东北向西北逐步加重的规律。② 2010年土地沙漠化灾害危险性较2000年减轻,特别是中度危险的土地大幅减少,其他等级土地保持稳定。③中国北方土地沙漠化灾害危险性减轻的主要驱动力是气候变化。人类活动对减轻风沙灾害起到了显著作用。
英文摘要	The hazard assessment of land sandy desertification has a significant scientific and practical value for the prevention and control of sandy desertification disasters. A theoretical framework and a comprehensive multi-indicator model were proposed for assessing sandy desertification hazard in this paper. Then, the sandy desertification hazard in north China was assessed. Results are as follows: ① Sandy desertification hazards in north China were mainly mild, slightly mild,moderate and slightly serious. The hazard degree increased gradually from the coastal areas to the inland and from the northeast to the northwest; ② The hazard degree of sandy desertification in north China was in a mitigation trend. Compared with 2000, land area with moderate hazard degree was reduced significantly, and the area with other grades remained stable in 2010; ③ Climate change was regarded as the main driving force of the mitigation trend of sandy desertification hazard in north China. Moreover,human activities played a significant role in reducing desertification disaster.
