基于GIS与地表覆盖的城乡划分实证研究——以武汉为例

Identification of Urban Boundaries Based on Geographic Information System and Land Cover: A Case in Wuhan

摘要: 正确的城乡划分是评估城市化水平的基础，快速城市化导致的城乡交接地区的用地快速变化和混乱程度加剧，造成城乡范围难以界定。本文提出一套可行的城乡实体用地的划分技术方法，并以武汉市为例，利用2010年地表覆盖数据及百万居民点分布数据进行实体地域的城乡划分。

Abstract: The correct urban-rural division is the basis for the assessment of the urbanization. Due to the rapid changes in urban-rural fringe, it is difficult to identify urban boundary in China. Defining city boundaries in urban-rural fringe is an enthralling challenge for urban planners. This paper presents a feasible technical method for identifying boundaries based on artificial land cover data in 2010. The method is tested on Wuhan city to identify its morphological boundaries.
