摘要: 多尺度空间格局研究对于全面了解建设用地变化具有重要意义。采用1989、2000和2009年的TM影像研究了郑州市建设用地景观的多尺度格局及动态。结果表明:1989—2009年,郑州市建设用地面积增长迅速,且其平均斑块面积呈单极增长趋势,农村建设用地面积增加较城市缓慢;在<13 km空间尺度上城市核心区建设用地面积逐渐增加,建设用地斑块的联通和扩张势态明显;13~25 km的尺度上建设用地景观表现为聚集-分散-聚集过程;25~58 km的尺度上建设用地景观表现为聚集-分散过程;在空间变化方面,郑州市辖区东部、北部和西南部建设用地景观增加速度最快,农村建设用地景观变异程度小于城市,郑州市辖区中部、郑州市西部和北部建设用地景观变化较小。

Abstract: The study of multi-scale spatial pattern is important to comprehensively understand the changes of construction land. In this paper, the TM images in 1989, 2000, and 2009 were used to study the multi-scale pattern and its dynamic changes of construction land in Zhengzhou. From 1989 to 2009, the area of construction land in Zhengzhou increased rapidly, and the patch’s mean area showed a unipolar growing trend. The area of rural construction land increased more slowly than that of urban construction land. At the scale level 0-13 km, the area of construction land in urban core increased gradually, and the patches of the construction land had obvious connection and expansion. At the scale level 13-25 km, the landscape of construction land showed a process of clusterdispersioncluster; while at the scale level 25-58 km, this landscape showed a process of dispersion cluster. Spatially, the area of construction land in the east, north, and southwest of Zhengzhou increased rapidly, the landscape of rural construction land had a smaller variation degree than that of urban construction land, and the landscape of construction land in the middle, western, and northern parts of Zhengzhou had less change.
