摘　　要：选取内蒙古东乌珠穆沁旗满都胡宝拉格草甸草原为研究区,在遥感和GIS技术的支撑下,以景观生态学理论为指导,通过分析该地区近15年来四个时期景观类型的空间格局、演化态势和变化规律,从景观视角挖掘出格局信息与生态环境变化之间的内在关联性,运用马尔科夫链模型对未来草原景观格局变化的趋势进行了模拟和预测,并分析了该地区生态环境变化的驱动机制,为科学利用和保护草地资源、保证区域可持续发展提供了科学依据。Selected the region of Manduhubaolage of Inner Mongolia as the study area, based on RS and GIS technology and supported by the theory of landscape ecology, the spatial pattern, trend and the law of landscape types during the four periods of the past 15 years in the area is studied. This paper excavates the internal relevant of the landscape pattern information and ecological environment change, analyzes and predicts the trend of the change of landscape pattern of meadow steppes and driving mechanism by using Markov chain model. The results could provide scientific basis for scientifically utilizing and protecting the grassland resources and maintain the regional sustainable development.
