中文摘要	采用1975年MSS数据,2000年TM数据,2007年TM数据为遥感信息源,通过建立科学的荒漠化分类体系与遥感解译标志,并结合地理信息系统方法,对陕西省荒漠化现状与19752007年近32 a来的动态变化特征进行了研究。结果表明,截止2007年,陕西省荒漠化土地面积8.23 * 10~4 km~2,占全省面积的40.15%。荒漠化类型多,包括沙质荒漠化、水蚀荒漠化与盐碱质荒漠化3类,以水蚀荒漠化为主,3种荒漠化类型分别占陕西省面积的7. 48%, 32. 37%和0. 3%;近32 a来,荒漠化土地面积持续逆转, 20002007年的逆转幅度大于1975 2000年。陕北长城沿线的沙质荒漠化与黄土高原的水蚀荒漠化出现明显逆转,陕南秦巴山地的水蚀荒漠化在总体逆转的间时,部分地区出现发展的态势。
英文摘要	Using MSS data in 1975,TM data in 2000 and 2007 as the source of information, the current situation and change of desertification of Shaanxi Province were studied from 1975 to 2007 through a scientific de sertification classification system and interpretion symbol,and suppotted with the geographic information system. The results showed that the total area of desertification was 82 300 km~2, accounted for 40. 15% of Shaanxi Province by the end of 2007. The desertification types include sandy desertification, water erosion desertification and salinization desertification. The main type was the water erosion desertification. The three types of desertification accounted for 7. 48%, 32. 37%,0. 3% of Shaanxi Province area, respectively. The desertification area keept reversing during the past 32 years, and the reversed amplitude of 20002007 was more than that of 19752000 years. The sandy desertification land along the Great Wall in Northern Shaanxi Province and the water erosion desertification land in Loess Plateau reversed obviously,the water erosion de sertification land in Qinba Mountains of Southern Shaanxi Province reversed on the whole,at the same time, some areas was developed.
