七台河市绿色基础设施网络演变规律及驱动力分析

Analysis on evolvement rules and driving force of green infrastructure network in Qitaihe

GI网络在资源型城市转型过程中起到了加快转型速度、改善城市环境的重要作用。选取七台河市这一典型的煤炭资源型城市作为研究对象,分析了该市2000—2018年GI网络演变规律。通过对七台河市社会经济统计数据的整理和分析,以及对城市发展政策的了解,归纳总结七台河市GI网络演变的主要驱动力因子。结果表明:在2000—2018年这一时期,七台河市GI用地面积先增加后减少,GI网络先快速破碎,后破碎化程度逐渐稳定,GI网络存在“破碎—恢复—稳定”的演变规律;人口与工业因子、城乡变化与其他产业因子、第一产业因子是造成七台河市GI网络演变的3个主要人为驱动因子;GI网络在演变过程中始终受到城市发展政策和转型政策的影响。

Green infrastructure network plays an important role in improving urban environment for resource-based city of Qitaihe,a typical coal resource-based city.The evolvement rules of green infrastructure network in Qitaihe from 2000 to 2018 is analyzed.The main driving factors of the evolution through the collation and analysis of the socioeconomic statistics of Qitaihe is summarized,with the understanding of urban development policy.The results showed that the area of green infrastructure land increased first and then decreased in Qitaihe during this period.The green infrastructure network was rapidly broken at first and then gradually stabilized.The green infrastructure network of Qitaihe expenienced the evolution of“fragmentation-restoration-stabilization”during this period population and industrial factors,urbanrural changes and other industrial factors,primary industry factors were the main driving factors.Green infrastructure network is always influenced by the urban development policies and transformation policies.
