中文摘要	本文基于宁夏中部干旱带土地沙化现状,进行土地沙化敏感性和沙漠化控制重要性评价。宁夏中部干旱带土地沙化敏感性分为极敏感、高度敏感、中度敏感、轻度敏感和不敏感5级。极敏感区主要集中在与腾格里沙漠接壤的沙坡头区的北部边缘地带,高度敏感区主要分布在与毛乌素沙地接壤的盐池县、灵武市和红寺堡区的大部分地区,中度敏感区广泛分布于土地沙化极敏感区和高度敏感区的周边地区,轻度敏感区呈带状分布于中度敏感区的四周,不敏感区分布在中部干旱带最南端地区。宁夏中部干旱带土地沙漠化控制重要性分为极重要、重要、较重要和不重要4级。极重要地区位于腾格里沙漠南缘的沙坡头区,重要地区分布于毛乌素沙地西部的盐池县、灵武市和红寺堡区的大部分地区,较重要地区主要在海原、同心等县域,不重要地区面积较小,呈带状分布,位于宁夏中部干旱带的沿河地带和最南部。
英文摘要	The aeolian desertification degree was analyzed in the middle arid region of Ningxia, then the integrated sensitivity to aeolian desertification and importance of controlling aeolian desertification in the middle arid region of Ningxia was assessed. The sensitivity to aeolian desertification in the middle arid region of Ningxia was classified into five sensitive grades as:extremely, highly, moderately, slightly and insensitive. The area of extremely sensitive to aeolian desertification was distributed in north Shapotou District, which was adjacent to the south Tengger Desert; the area of highly sensitive was located in Yanchi County, Lingwu City and Hongsibao District, which was adjacent to the west Mu Us Sandy Land; the area of extremely and highly sensitive was surrounded by the moderately and slightly sensitive area; and the area of insensitive lied in the most south of the middle arid region of Ningxia. The importance of controlling aeolian desertification in the middle arid region of Ningxia was divided into four important grades as:extremely, important, moderately and unimportant. The area with extreme importance of controlling aeolian desertification was distributed in north Shapotou District, which was adjacent to the south Tengger Desert; the area with importance of controlling aeolian desertification was distributed in Yanchi County, Lingwu City and Hongsibao District, which was adjacent to the west Mu Us Sandy Land; the area with moderate importance was distributed in Haiyuan County and Tongxin County; and the area with no importance of controlling aeolian desertification was distributed in the most south of the middle arid region and along the Yellow River.
