建成区

建成区（英語：built-up area）一般指城市中的城市化区域。

中国大陆

在中国大陆，《城市规划基本术语标准》（GB/T 50280-98）将“城市建成区（urban built-up area）”定义为“城市行政区内实际已成片开发建设、市政公用设施和公共设施基本具备的地区”。中国大陸统计部门用建成区来反映一个市的城市化区域的大小。具体指一个市政区范围内经过征用的土地和实际建设发展起来的非农业生产建设的地段，包括市区集中连片的部分以及與城市中心有密切關聯的近郊区域，具有基本完善的市政公用设施的城市建设用地（如机场、污水处理厂、通讯电台）。建成區範圍一般是指建成區外輪廓線所能包括的地區，也就是這個城市實際建設用地所達到的邊界範圍，因此，它是一個閉合的完整區域，一城多鎮分散佈點的城市，其建成區範圍則可能由幾個相應的閉合區域組成。

英國

英国国家统计署对建成区（built-up area）的定义如下：

建成區是「具有不可逆的城市特徵」，即有鄉村、鎮或城市特徵的土地。它們包括至少20公頃（200,000平方米；49英畝）的建築用地。任何間隔不到200米的非城市空間區域都連接視為同一建成區。^[1]

Built-up areas are defined as land which is ‘irreversibly urban in character’, meaning that they are characteristic of a village, town or city. They include areas of built-up land with a minimum of 20 hectares (200,000m2). Any areas with less than 200 metres between them are linked to become a single built-up area.
