中文摘要	依托甘肃省第4次荒漠化监测结果,研究了民勤县荒漠化土地现状和空间分布状况,对区域内荒漠化类型、程度、分布特点等展开系统阐述,并结合第3期监测结果,就相关指标的动态进行了分析。结果表明:(1)民勤县荒漠化土地总面积1 445 208.3hm~2,其中风蚀荒漠化1 319 134.3hm~2、盐渍化126 074.0hm~2。2004-2009年荒漠化年转化率为-0.019%,总体呈逆转趋势,具体表现为轻度略增加、中度和重度呈较快增长、极重度大幅递减。(2)民勤县土地荒漠化程度整体呈减轻的趋势,土地荒漠化变化受人为因素和自然因素的共同作用,其中人为因素占主导地位。
英文摘要	On the basis of RS,GIS and the fourth desertification monitoring in Gansu province,this study was to monitor the spatial distribution condition and distribution characteristics of desertification land in Minqin,Gansu,China by multiple factor quantification evaluation.The dynamic change of desertification degree and type were analyzed by the method of comparison analysis.The result showed that the total area of land desertification was 1 220 451.4 hm~2.From the type of desertification land,the areas of wind-eroded desertification land and salinized desertification land were 1 319 134.3 hm~2 and 126 074.0hm~2,respectively. The development of land desertification reversed,in which the area of slight desertification land was increased small,the area of moderate and serious desertification land enlarged rapidly,and the area of extremely serious desertification land decreased sharply.The prospect of researches in this field lies in predicting the trend of desertification development and analyzing the reason of desertification in Minqin,in order to provide scientific bases for ecological construction and restoration.
