摘要：将磴口县作为研究区,按照荒漠景观和绿洲景观两大主要景观类型对1989,1995,2000,2007,2010和2014年遥感影像进行分类,利用荒漠绿洲景观重心迁移模型、转移矩阵和景观格局指数系统研究了磴口县荒漠绿洲景观时空演变以及格局特征。结果表明:1)25年来荒漠景观逐渐向西北迁移,绿洲景观逐步扩张,积极的沙漠化治理获得成效。2)严重沙漠化景观和重度沙漠化景观大面积转出为其他景观,中度和轻度流转最为频繁,非沙漠化景观逐渐成为主体景观。3)轻度沙漠化景观和中度沙漠化景观破碎化程度较大,轻度沙漠化景观的人类干扰程度更大,斑块更为复杂。
The study area is located at the Deng Kou country,Six scenes of remote sensing images of different times（ 1989,1995,2000,2007,2010 and 2014） were classified according to the two main landscape types： desert and oasis landscape： the gravity center model,transfer matrix and landscape pattern index were used to study the desert oasis landscape pattern evolution and characteristics. The results showed that： 1） The desert landscape was moved to the northwest gradually during the past 25 years. Oasis landscape was expending gradually,the positive desertification control was success. 2） Serious desertification and severe desertification landscapes were rolled out to other landscape and the area was large. Moderate and mild were circulating the most frequently. Non desertification landscape had become the main landscape gradually. 3） The mild and moderate desertification landscape fragmentation degrees were high,human disturbance degree for the mild desertification landscape was bigger,plaque was more complicated.
