摘要
以西咸新区为例,借助三期高分二号卫星影像数据和一期北京二号卫星影像数据,利用Arc GIS软件提取新区四期建成区范围和3个时段建成区变化数据,结合建成区扩展指标和八方向扩展模型对新区建成区扩展进行了时空分析,进而客观分析了新区建成区扩展的主要驱动力。结果表明:西咸新区2018年建成区面积是2015年的1.5倍,且新区南部建成区扩展更为明显,通过对自然、经济、社会、历史、文化和政策等建成区扩展因素进行分析,得出区位、政策、经济和交通因素是其扩展的主要驱动力。
Taking Xixian New Area as an example,this paper uses Arc GIS software to extract the change data of the built-up area of three time intervals,boundary of built-up area of the new area of four periods,combines the expansion index of the built-up and the eight-direction expansion model to carry out spatial analysis of the expansion of the built-up area of the new area,and further objectively analyzes the main driving force for the expansion of the built-up area of the new area.The results show that the area of the builtup area of Xixian new area in 2018 is 1.5 times of that in 2015,and the expansion of the southern built-up area of the new area is more obvious.By analyzing the expansion factors of built-up areas such as nature,economy,society,history,culture,and policy,it is concluded that location,policy,economic,and transportation factors are the main driving forces for its expansion.
