大庆城市建设用地演变及驱动力研究

Study on the Evolution and Driving Forces of Urban Construction Land in Daqing city

研究大庆城市建设用地演变对于促进大庆新型城镇化发展、推动哈大齐工业走廊建设都具有重要意义。选取大庆市2000、2005、2010、2015年4个时间节点的Landsat 8的遥感影像,依托ENVI、Arcgis、91卫图技术处理4期城市建设用地数据,并结合《中国城市统计年鉴》的城市建设用地统计数据进行校正。研究发现,大庆市15年间城市土地扩展方式从单一方向到多方位演变,且以外延式扩展为主,"摊大饼"特征比较明显。城市主要扩展方向经历了"北拓、东移、南进"的空间转变过程。其城市建设用地演变主要受国家和地方政策影响,此外还受经济发展、人口增加、交通基础设施建设等多种因素影响。

Study on the Evolution of Daqing Urban Construction Land to promote the development of new urbanization in Daqing and promote the industrial corridor construction of Harbin, Daqing and Qiqihar are of great significance. The remote sensing images of Landsat 8 from four time nodes in Daqing 2000, 2005, 2010 and2015 were selected, relying on ENVI, Arcgis, 91 Weitu technology to deal with four urban construction land data,and combined with the＂China Urban Statistical Yearbook＂of urban construction land to correct the data. The study found that 15 years Daqing urban land expansion mode evolved from a single direction to the multi-faceted evolution, and the epitaxial type of the main extension,＂Pizza pie＂features more obvious. The main direction of the city has gone through ＂north expansion, goes east, south forward＂of spatial transformation process. The evolution of urban construction land is mainly affected by national and local policies. In addition,it is also affected by economic development, population increase,transportation infrastructure construction and other factors.
