摘要: 剖析矿业城市建设用地景观空间布局与演变特征,不仅有助于解决生态环境问题,而且能为优化城市用地结构、及时采取转型干预措施提供科学依据。以典型矿业城市——大同市为例,基于1986—2018年建设用地空间分布数据,运用景观指标分析法研究建设用地景观的时空分异特征,并通过傅里叶变换和小波变换的图谱检测景观变化周期。结果表明: 研究期间,大同城市建设用地面积不断增加,但增速逐渐放缓,范围由“东北-西南”方向的带状区域向东蔓延。景观格局的破碎度和复杂度不断增加,物理连通性逐渐降低,功能连通性呈高低值交替变化。大同城市的空间扩张及建设用地景观格局的破碎化和复杂化可能均存在大约35年的周期,景观功能连通性的周期长于物理连通性。

Abstract: Analyzing the landscape spatial layout and evolution characteristics of built-up land in a mining city is helpful to solve the environment problem, and can provide scientific basis for optimizing the urban land structure and taking timely intervention measures for transformation. Taking Datong, a typical mining city as the case, we examined the spatiotemporal characteristics of landscape of built-up land based on the spatial distribution data of built-up land from 1986 to 2018 with the landscape index analysis method, and detected the landscape change period with graphs obtained by Fourier transform and wavelet transform. The results showed that, during the study period, the area of built-up land in Datong City increased continually, with the growth rate gradually slowing down and the extent spreading from a “northeast-southwest” belt zone to the east. The fragmentation and complexity of the landscape pattern were increasing. The physical connectivity gradually decreased, while functional connectivity alternated between high and low values. The space expansion of Datong City and the fragmentation and complication of landscape pattern of its built-up land may all have a cycle of about 35 years, while the functional connectivity had a longer cycle than the physical connectivity.

Key words: mining city, landscape pattern, long time series, period
