摘要

[目的]探讨不同尺度下太原市城市景观格局的时空变化特征，以期为解释城市化进程中景观格局演变的时空规律、评估社会经济发展对其的影响提供重要的科学依据。[方法]基于2000—2015年3期时间序列的Landsat TM遥感影像获得一级景观类型的太原市土地利用覆盖空间数据，利用Fragstats 3.4软件计算景观格局特征指数，研究太原市全市域和主城区的城市景观格局时空变化特征，并利用SPSS软件系统剖析了影响太原市景观格局的驱动作用。[结果]①15 a间，林地、耕地和草地始终是全市域的主要景观类型，分别占总面积的比例由33.60%，31.80%和27.47%变化为35.18%，27.97%和25.49%。城乡、工矿、居民用地的面积明显增加，占总面积的比例由5.86%增长为10.27%，其中耕地和草地是城市化用地扩张的主要来源；主城区土地利用的强度呈逐年增加的趋势，城乡、工矿、居民用地占总面积的比例由21.65%增长为33.82%，成为主城区的主要景观类型，而城乡、工矿、居民用地占用耕地的数量比全市域更加明显。②在全市域尺度上，景观格局指数变化表现为耕地、林地的斑块破碎化程度高，景观蔓延度下降，景观多样性增加；而主城区尺度上城乡、工矿、居民用地斑块破碎化程度显著升高，景观蔓延度呈先下降后上升的趋势，但景观多样性却呈先上升后下降的趋势。[结论]太原市全市域和主城区尺度上的城市景观格局特征存在一定的差异性，社会经济的发展、政策因素以及城市规划与发展理论的阶段性调控作用是影响其演变的主要驱动力。

Abstract

[Objective] To discuss the spatial-temporal variations of urban landscape pattern in Taiyuan City in different scales

and expected to provide an important scientific basis for explaining the spatial-temporal pattern of landscape pattern evolution in the process of urbanization and evaluating the impact of social-economic development.[Methods] The research was based on 3 time series of Landsat TM remote sensing images from 2000 to 2015. We used the spatial distribution of land use in level 1 of landscape types

and used Fragstats 3.4 software to calculate the landscape pattern characteristic index in Taiyuan City

studied the temporal and spatial variation of the urban landscape pattern in the whole city and the main urban area of Taiyuan City. And then we analyzed the driving effect of landscape pattern in Taiyuan City used SPSS software system.[Results] ① In the past 15 years

woodland

cultivated land and grassland have always been the main landscape types in the whole city. The proportion has changed from 33.60%

31.80% and 27.47% to 35.18%

27.97% and 25.49% respectively. The area of urban-rural

industrial-mining and residents land increased significantly. The proportion increased from 5.86% to 10.27%

among which cultivated land and grassland were the main sources of the expansion of urbanization land. Land use intensity in the main urban area showed an increasing trend. The proportions of urban-rural

industrial-mining and residents land increased from 21.65% to 33.82%

became the main landscape types in the main urban areas

and the proportion of arable land decreased from 27.04% to 37.54%

the amount of cultivated land occupied by urban-rural

industrial-mining and residents land was more visible than that of the whole city. ② In the whole city scale

The patch fragmentation of cultivated land and woodland is high

the landscape contagion decreased

landscape diversity increased. In the main urban area scale

however

urban-rural

industrial-mining and residents land fragmentation degree increased

landscape contagion increased after an initial decrease

but the landscape diversity decreased after an initial increasing trend.[Conclusion] Urban landscape pattern in the whole city are different definitely with which in the main urban area of Taiyuan City. Social-economic development

policy factors

and the phasing regulation role of urban planning and development theory are main driving forces of the evolution of urban landscape pattern in Taiyuan City.
