摘要
以大连金普新区建成区为研究实验对象,对2013—2018年的新区建成区的8个方向面积及变化情况进行统计,分析建成区重心指数变化、发展态势和建成区扩展强度,并以金州新区为例,计算该建成区各地表覆盖类型在8个方向的相对变化率。得出新区建成区范围不断扩张,重心指数不断变化;各建成区均在不同方向的扩张强度持续增加;金州新区内各地表覆盖类型在东北方向的变化最为显著。本次研究可以清晰地掌握城市发展的脉络,进一步引导新区建成区健康平稳发展。
Taking the Jinpu new built-up area of Dalian as the research object,in this paper,it made statistics on the eight directions of the built area from 2013 to 2018,analyzed the change of the center of gravity index and the expansion intensity of the built area,and calculated the relative change rate of the surface coverage types in the eight directions of the built area.It was concluded that the scope of the built-up areas in the new area kept expanding and the center of gravity index keeps changing;the expansion intensity of each built-up area kept increasing in different directions;the change of the surface coverage types in the Jinzhou new area was the most significant in the Northeast direction.
