摘 要: 为更好地表征博斯腾湖流域的景观格局,将土地经济生态位的理论和方法引入景观生态学中,以1990年、2000年、2005年、2010年和2015年5期30 m分辨率遥感影像及相应的统计年鉴为数据源,计算博斯腾湖流域不同时期的土地经济生态位及景观格局指数,并分析不同土地利用类型经济生态位与景观格局指数间的相关关系,此外,从年份、土地类型两个角度进行基于均数的对应分析。结果表明:1)博斯腾湖流域林地、草地、水域用地及耕地的土地经济生态位均上升,而建设用地的土地经济生态位下降;2)进行单一相关性分析时,不同土地利用类型与景观格局指数中的一个或几个指标有较强的相关关系;3)进行综合相关性分析时,博斯腾湖流域的建设用地、耕地及水域用地的土地经济生态位与相应的斑块类型面积、平均斑块面积及聚合度指数有显著的相关关系。土地经济生态位的变化对博斯腾湖流域的景观格局具有驱动作用,可以较好地解释该流域的空间景观格局特征。
关 键 词: 地理学;土地经济生态位;景观格局指数;相关性;博斯腾湖流域

Abstract: In order to better represent the landscape pattern of Bosten lake basin, this paper introduces the theory and method of land economic niche into landscape ecology. 30 m resolution remote sensing images and corresponding statistical yearbooks in 1990, 2000, 2005, 2010 and 2015 as data sources are used to calculate the land economic niche and landscape patten index of different periods in Bosten lake basin, and to analyze the correlation between economic niche of different land use types and landscape patten index, and the corresponding analysis based on the mean from the two perspectives of the year and land types. Results showed that: 1) The land economic niche of forest land, grassland, waterland and cultivated land in Bosten lake basin increased, while the economic niche of construction land decreased; 2) When conducting single correlation analysis, one of different land use types and landscape pattern indexes, or a number of indicators, have a strong correlation; 3) In the comprehensive correlation analysis, there is a significant correlation in the land economic niche of the construction land, cultivated land and waterland in Bosten lake basin with the corresponding plaque type area, average plaque area and polymerization index. It is concluded that the change of land economic niche has a driving effect on the landscape pattern of the Bosten lake basin, which can better explain the spatial landscape pattern characteristics of the basin.
Key words: geography; land economic niche; landscape pattern index; correlation; Bosten lake basin
