以半荒漠地区乌梁素海湿地为研究区域,利用GIS、RS技术结合景观生态学的理论和方法,对1986-2008年不同时间、空间粒度的多源遥感影像进行信息提取,描述不同类型区景观斑块指数动态变化,进行湿地生态资源时空异质性分析,对乌梁素海湿地类型区之间的演化关系和演化方向进行研究,定量分析湿地各类型区景观动态演化趋势.结果表明:景观破碎化程度降低,明水区丧失,水下水草丛生,以芦苇为主的大型挺水植物平均面积约占湿地的49%以上,是湖泊湿地类型区演化的主导类型.湿地时空格局演变和气候、水文条件及人为影响相关,再现了人类活动对湿地景观的干扰过程和干扰强度.

The information of multi-source remote sensing images of Wuliangsuhai wetland at dif-ferent time and space granularity from 1986 to 2008, which lies in the semi-desert area, was ob-tained by GIS and RS technology combined with the theories and methods of landscape ecology. The dynamics of landscape patch index for different types of areas was described and the spatial-temporal heterogeneity of wetland ecological resources was analyzed. Evolutionary relationship and direction among various wetland types of Wuliangsuhai were researched. The dynamic evolution trends of various types of wetland landscape were analyzed. The results showed that the degree of landscape fragmentation was reduced, the water district was lost, and underwater plants were tuft-ed. The average area of reed-based large hyper-surface plants was above 49% of wetland, which was the dominant evolution type of the lake wetland. Evolution of spatial and temporal patterns of wetlands was related to climate, water conditions and artificial impact, which reflected the process and intensity of human disturbance on wetland landscape.
