基于GIS城市建成区范围界定方法实证研究——以奉化建成区为例

长期以来,我国对建成区边界的界定缺乏行之有效、统一的操作手段,而随着城市化的快速发展,建成区范围的界定就显得较为滞后。本文尝试从属性、功能、形态三个方面来界定建成区范围,并在此基础上构建较为精准的建成区调查地理信息系统平台,以期为建成区的判定探索出快速有效的方法。奉化建成区实证研究表明,该判定方法较为精准,再经过人工修正,就可以得出精确的建成区边界。

Empirical Study on the Method of Defining Urban Built-up Area Based on GIS: Take Fenghua Built-up Area as an Example

For a long time , the definition of the boundary of the built area lack of effective and unified means of operation .With the rapid development of urbanization , the definition of built -up area is lagging behind .Therefore , this paper attempts to define the scope of the built-up scope from three aspects:attribute, function and form.On the basis of investigation and geographic information system platform to build more accurate proper .According to the empirical study of Fenghua District , it is shown that the method are more accurate , and then the artificial boundary can be obtained by artificial correction .
