摘要: 随着国家新农村建设和新型城市化的稳步推进,乡村景观格局的变化开始受到广泛关注,特别是相对闭塞的少数民族乡镇,理解其景观格局的时空变化对于探索民族乡镇发展至关重要.本研究基于景观生态学理论,利用典型达斡尔族少数民族乡镇——阿尔拉镇2008—2013年间的土地利用矢量数据,通过ArcGIS和 Fragstats软件计算景观格局指数,从类型水平和景观水平上对景观格局变化进行分析.结果表明: 在类型水平上,研究区农、林、草地逐渐向建筑用地转移;在景观水平上,景观多样性指数偏低,异质性较高,连通性不强,景观破碎化程度较高.将景观指数与社会经济指标进行典型性相关分析和灰色关联分析,发现人口的变化和GDP的增长是研究区景观格局变化的最主要驱动因子.最后,结合经济、文化、政策、自然等因素探讨了导致阿尔拉镇景观格局演变的主要驱动因素,并给出相应对策,该结果可为我国东北少数民族聚居区的发展提供基础信息和理论依据.

Abstract: With the stable development of new countryside construction and new-type urbanization, the changing of the landscape pattern in countryside attracts more attention, especially in the ethnic townships which are hardly accessible. To explore the development of these areas, it is crucial to understand the spatial and temporal variation of the landscape pattern. In this paper, the landscape pattern change was analyzed at both patch type level and landscape level based on the landscape ecology theory. The land use data (format: vector) got from Aerla Town (a typical Daur ethnic township in Inner Mongolia) for the duration from 2008 to 2013 was studied by ArcGIS platform and Fragstats. For the type level, the grassland, farmland, and forest turned into building land gra-dually. Regarding the landscape level, the landscape diversity index and landscape connectivity index were relatively low, the heterogeneity index and the landscape fragmentation were relatively high. With considering the correlation analysis and grey correlation of the above indexes as well as the social and economic development in Aerla Town, the results indicated that population change and GDP growth were the main driving forces of landscape pattern change. Finally, the driving forces which resulted in the variation of landscape pattern with the incorporation of the economic, cultural, policy, and natural effects were discussed. The research could provide basic information and theoretical foundation for the development of minority areas in Northeast China.
