武汉1+8 城市圈担负着“中部崛起”的重任，在国家经济发展过程中具有举足轻重的地位。本文从空间格局 角度，结合最新的行政区划、基础地理数据库及其统计资料，利用GIS 空间分析方法，对武汉城市圈内部各城市区 位和交通可达性进行了定量分析。结果表明，与全省其他县市相比，目前武汉城市圈内各城市具有明显区位优势。 在圈内8 个地级市当中，孝感市具有最高的区位指标，而潜江、仙桃、天门等三个省直辖市区位指标较低。城市圈各 城市出行时距沿高速公路与国道以及各级道路呈放射状延伸。城市圈内城市间基本实现2 小时可达。武汉和孝感 市拥有最高的出行时距增长速率，天门、黄石和咸宁市出行时距增长速率较低，迫切需要加强其周边交通网络基础 设施的建设。

Wuhan “1 +8”metropolitan region plays an extremely significant role in central China's construction as well as in the process of national economic development. From the perspective of spatial pattern, this paper adopts the latest administrative division data, fundamental geographic information database and statistic data to conduct quantitative analysis on both transportation accessibility and regional superiority of the present cities within Wuhan metropolitan region. The result shows an obvious regional advantage for the cities compared with other cities in the province. More specifically, Xiaogan occupies the highest indicators in location among all the 8 cities inside the region while Qianjiang, Xiantao and Tianmen comparatively rank behind. Each city is accessible within two hours from other cities in the region. Wuhan and Xiaogan have the highest increasing speed for traveling time distance, while Tianmen, Huangshi and Xianning behave weak and heed to improve their infrastructure construction.
