摘要：

暴露度理论是分析人地相互作用过程的桥梁。本文以快速城市化带来的影响作为主要干扰因素,选取杭州城市边缘区所辖街道为基本单位,以距市中心距离、斑块密度、香农多样性指数、景观分割度指数、建设用地比重、最大斑块指数6方面指标构建暴露度评价指标体系,并结合熵值法对杭州市城市边缘区暴露程度的空间分异特征及其影响因素进行了研究。结果表明：（1）杭州市城市边缘区暴露度总体分布规律并非是从城东向城西逐渐递减,而是呈现出高、中、低3个等级相间排列的现象;（2）结合当前杭州市社会经济数据,发现空间分异状况、城市系统体制转换阶段差异对杭州市边缘区的暴露程度均有一定的影响。

Abstract:

The exposure degree theory is a bridge to analyze the process of human-land interaction. This paper considered the impact of rapid urbanization as the main interference, and selected the streets under the jurisdiction of Hangzhou’s urban fringe as the basic unit. The distance from the city center, patch density, Shannon’s diversity index, landscape segmentation index, construction land proportion and maximum patch index were used as indicators to establish exposure index system, and the entropy method was applied to clarify the spatial differentiation characteristics of the exposure degree and its influencing factors in urban fringe of Hangzhou. The results showed that (1) the overall distribution of exposure degree in the urban fringe of Hangzhou was not gradually decreasing from east to west, but showed a high, middle and low grade alternate arrangement; (2) combined with the current social and economic data of Hangzhou, it was found that the spatial differentiation and the difference of urban system transition stage had certain impact on the exposure degree in the urban fringe of Hangzhou.

Key words: urbanization, land use, exposure degree, urban fringe, Hangzhou
