摘　　要：生态园林城市是人与自然和谐相处的最佳城市形态,建设生态园林城市对城市绿地景观格局优化具有重要作用。以徐州市2004年和2014年的Quick Bird卫星影像为信息源,运用地理信息系统技术,选取斑块平均面积、斑块密度、香农多样性指数、香农均匀度指数、最小距离指数和廊道密度等,对徐州市在国家生态园林城市建设驱动下的绿地景观格局变化进行研究。结果表明:2004—2014年,徐州市城市绿地斑块平均面积从0.17 hm^2增加到0.40 hm^2,斑块密度从5.97个/hm^2降低到2.45个/hm^2,廊道密度从1.12 km/km^2增加到2.32 km/km^2,公园绿地最小距离指数明显增加。这说明在国家生态园林城市建设驱动下,徐州市中心城区的绿地数量在增长的同时,景观格局也在不断优化,主要表现为:绿地斑块增大、破碎度降低、景观连接度明显提高、防护绿地功能增强、公园绿地分布向均匀化发展,这些变化对保护城市生物多样性、提升城市绿地系统生态功能、方便居民使用起到重要作用。Eco-garden city is the best city form for people to get along with nature harmoniously,so the construction of eco-garden city plays an important role in the optimization of urban green landscape pattern.Taking the Quick Bird satellite image data as main information source,using remote sensing and GIS,selecting the index such as the average patch area,patch density,Shannon diversity index,Shannon evenness index,minimum distance index and corridor density,the dynamic changes of green space landscape pattern in central city of Xuzhou from 2004 to 2014 driven by the construction of eco-garden city were analyzed.The results showed that the average patch area of urban green space increased from 0.17 hm^2 to 0.40 hm^2,the patch density decreased from 5.97/hm^2 to 2.45/hm^2,the corridor density increased from 1.12 km/km^2 to 2.32 km/km^2 and the minimum distance index of public park increased singnificantly,which demonstrated that pattern of the green space landscape was constantly optimizing while the number of the green space landscape was increasing in the central city of Xuzhou,for example,the average area of green patches increased,landscape connectivity was significantly improved,function of protective green space was enhanced and the public parks was well-distributed,which played an important role in protecting biodiversity,stabilizing of urban ecosystem and facilitating public access to parks.
