摘要：陕西北部地处毛乌素沙地南缘,是陕西省荒漠化、沙化土地的主要分布区。土地的荒漠化、沙化严重影响到当地人民的生产、生活和发展,成为制约陕西经济可持续发展的主要瓶颈之一。为准确掌握陕西省荒漠化和沙化土地的现状及动态变化趋势,按照国家要求,陕西省已开展了4次(即1994、1999、2004、2009年)荒漠化、沙化监测工作。研究采用这4期监测数据,通过对15a来监测数据的分析比较。结果表明,1994-2009年15a来,陕西省沙化总面积减少了34 974.9hm2,平均每年减少0.16%;1999-2009年10a来,陕西省荒漠化土地面积减少了166 337.9hm2,平均每年减少0.53%。15a来,陕西省通过实施以生态建设为主的林业发展战略,是荒漠化和沙化整体扩展趋势得到初步遏制的主要原因。
Northern Shaanxi is located in the southern margin of Maowusu sandy land, it is the main distribution area of desertification in Shaanxi Province. Land desertification seriously affects the production, living and development of the local people’s becomes one of the main bottlenecks for the sustainable economic and social development. In order to accurately understand the current situations of desertification and dynamic changes, mornitoring and surveying on desertification were carried out four times （1994, 1999, 2004, 2009） in Shaanxi Province. Based on the investigation of the data obtained, it was found that from 1994 to 2009, the total area of desertification reduced 34 974.9 hm^2, 0.16% annually. From 1999 to 2009, the area of desertification decreased 166 337.9 hm^2, 0.53% annually. The main reason for the decrease of desertification in the past 15 years was the implementation of ecological construction in the development of forestry in the province.
