中文摘要	将磴口县作为研究区, 从景观大尺度入手按照荒漠绿洲景观分类系统对1989, 1995, 2000, 2007, 2010和2014年遥感影像进行分类, 综合利用GIS分析技术、景观利用动态分析方法与模型以及景观格局指数, 系统研究了磴口县荒漠绿洲景观格局特征及其时空演变过程。结果表明, 景观水平上, 磴口县景观斑块趋于连片化, 破碎化降低且景观内部组分比例逐渐均匀; 类型水平上, 优势景观逐步演替: 严重中度轻度非沙漠化, 依托水体景观而生的非沙漠化景观正在占据主导地位; 25年来, 经过一系列的生态修复, 严重、重度沙漠化景观面积减少, 中度与轻度沙漠化景观大面积转出, 与水体景观关系密切的非沙漠化景观逐步发挥其生态功能, 区域总动态度逐步稳定。
英文摘要	The study area is located at Dengkou County in Inner Mongolia of China. Six scenes of remote sensing images of different times (1989, 1995, 2000, 2007, 2010 and 2014) were classified according to the degrees of desertification in a landscape scale. GIS analysis technology, land use dynamic analysis method and landscape pattern index were used to study the landscape pattern characteristics and spatial temporal evolution of desert oasis in Dengkou County. The results showed that at the landscape level, the landscape patches in Dengkou County tended to be contiguous; the degree of landscape fragmentation decreased gradually; the proportion of the internal landscape group was gradually homogenization. At the type level, dominant landscape succeed as severemoderatemildnon-desertification. The non desertification landscape based on the water landscape occupied the leading position. During the 25 year period, after a series of ecological restoration, the area of serious and severe desertification landscape decreased gradually. Large areas of moderate and mild desertification landscape turned into other landscape. The non desertification landscape closely related to the water landscape was gradually playing its role of ecological protection, and the regional total dynamic degree gradually stabilized.
