中文摘要	中国干旱半干旱地区是连接中国与丝绸之路经济带沿线国家的重要纽带,严峻的土地沙漠化形势制约其可持续发展。研究沙漠化进程及驱动机制对防治沙漠化具有重要意义。基于2000年和2015年两期中国北方沙漠化土地、气象数据、人口、GDP、DEM、土壤类型数据,运用地理探测器方法研究了中国干旱半干旱地区沙漠化进程驱动力。结果表明,(1)2000-2015年,沙漠化面积减少了97700 km~2,其中轻度、极重度沙漠化面积分别减少了62000 km~2和130600 km~2,而中度和重度沙漠化面积分别增加了21500 km~2和73400 km~2。整体上,沙漠化逆转面积为386300 km~2,其中明显逆转239000 km~2,不明显逆转147300 km~2,而沙漠化发展面积为421800 km~2,其中明显发展142200 km~2,不明显发展279600 km~2。(2)2000-2015年,沙漠化进程是自然和人为因素共同作用的结果,但以自然因素为主要驱动力,其中沙漠化对气候因素响应尤为敏感,而降水量对沙漠化进程影响最大,平均相对湿度的影响次之。(3)气候因素间的交互作用对沙漠化进程影响显著,而平均相对湿度、降水量、日照时数与其他气候因素的交互作用更明显。
英文摘要	The arid and semi-arid region of China is an important bond connecting China and the countries along the Silk Road economic belt,but severe situation of land desertification restricts the sustainable development in the region.It is of great significance to study the process and driving mechanism of desertification in order to prevent and control desertification.On the basis of the desertification in the northern part of China in 2000 and 2015,meteorological data,population,GDP,DEM and soil types,the paper studied on the driving factors in desertification process in arid and semi-arid region of China by geographical detectors method.Results were as follows:(1) From 2000 to 2015,desertification decreased by 97700 km~2.Slight desertification and extremely severe desertification decreased by 62000 km~2and 130600 km~2,respectively.Besides,moderate desertification and severe desertification increased by 21500km~2 and 73400 km~2,respectively.Generally,the area of desertification reversal was 386300 km~2,and the area where desertification obviously reversed was 239000 km~2,and the area where desertification slightly reversed was 147300 km~2.The area of desertification development was 421800 km~2,and the area where desertification evidently developed was 142200 km~2,and the area where desertification slightly developed was 279600 km~2.(2) From 2000 to 2015,desertification process was a comprehensive result that was pushed by physical factors and human activity,but main driving forces were physical factors.Desertification was particularly sensitive to climatic factors,and precipitation had a greatest impact on desertification processes,and mean relative humidity merely had a less effect than precipitation.And (3) the interaction among climatic factors had an evident effect on the desertification process,and the interaction between mean relative humidity,precipitation,sunshine hours and other climatic factors was greater obvious.
