摘要：

随着社会经济的快速发展和人民生活水平的提高,提供良好优质的公共产品服务,加快推进社会主义和谐社会建设,是当今政府的题中应有之义。其中, 空间可达性是公共产品服务的核心内容之一,而这正是地理学最具优势的研究领域。本文基于所开发的公共产品空间布局决策支持系统,以仪征医院空间布局为例,从定量角度深入探讨了不同布局方案所产生的空间效应,为优化公共产品的空间布局提供了非常有说服力的科学依据,同时也从方法论角度进行了公共产品空间布局量化研究的有益尝试。

Abstract:

Along with the rapid development of socioeconomy and the great improvement of people's standard of living, to provide high quality public service and build a harmonious society is a primary task of the government. Fair space is the key principle of public service. It involves spacial accessibility and spacial attainability, and the former is the foundation and precondition. In this paper, based on the public product layout decision support system, we take an example of the hospitals in Yizheng city, analyze the spacial effect of different distribution of them from the aspect of accessibility, and provide powerful support for optimizing the supply of public product. And moreover, it gives a good sample of quantitative analysis on the public product layout. Through the case study of Yizheng city, we think there are two basic indices to measure the fair space of public product. The first is quantity index. For Yizheng city, we choose the accessibility of half an hour as quantitative target to optimize the public product layout. The second is quality index. We choose accessibility's distributing frequency and cumulative frequency of five minutes' interval as quality standard. In other words, for the same accessibility of half an hour but different distribution, it means different fair space. Therefore, it is a further study on the conception and methodology of fair space.

Key words: public product, spacial accessibility, fair space, Yizheng city
