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<13km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;13~25km的尺度上建设用地景观表现为聚集-分散-聚集过程;25~58km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。
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.
