Urbanization is the most drastic form of land use change, which affects the biodiversity and ecosystem functioning and services far beyond the limits of cities. Based on the land use data in three time periods and by the method of landscape pattern analysis, this paper analyzed the change characteristics of the spatiotemporal pattern of urbanization in the four Banners of East Erdos at different spatial scales. Urbanization had profound effects on the local ecology, society, and economics. The landscape as a whole became more fragmented and complex, and different patch types exhibited distinctive spatial characteristics and were affected to different degrees at class-level. Desert and urban land varied greater, and cropland was most affected by urbanization. Resources factors, increase of urban population, and development of economy were the main socio-economic driving factors to the changes in the local landscape spatiotemporal pattern of urbanization.
城市化是土地利用变化最剧烈的形式，其对生物多样性、生态系统功能及服务的影响远远超出城市范围。基于三个时期的土地利用数据，运用景观格局分析方法，本文分析了鄂尔多斯东部四旗不同空间尺度上城市化时空格局的变化特征。城市化对当地生态、社会和经济产生了深远影响。整体景观变得更加破碎和复杂，不同斑块类型呈现出独特的空间特征，在类别层面受到的影响程度各异。沙漠和城市用地变化较大，耕地受城市化影响最大。资源因素、城市人口增长和经济发展是当地城市化景观时空格局变化的主要社会经济驱动因素。
