【摘要】：SARS疫情在我国的迅速传播已经对我国的社会和经济生活造成了重大的影响 ,也为我们观察和分析地理扩散提供了难得的机会。SARS的扩散显然是一种地理过程 ,这个过程的第一个特征是以等级扩散为发展方式的 ,第二个特征是必然在扩散中遇到障碍。第一个特征的存在使疫情在一段时间里在我国得以迅速的蔓延 ,但是当采取各种医疗、隔离和防护措施后 ,SARS的扩散在出现障碍的条件下受到抑制。文章描述了疫情扩散的方式 ,在我国形成的地理格局 (以广东和北京为源地 ) ,认为这个地理格局的形成与我国流动人口的分布、人口流动的条件有关。同时指出 ,在疫情扩散的地理格局中 ,在中心城市形成的高度集中是一种令人担忧的现象。因为这样的集中已经对这些中心城市的包括“医疗中心”在内的行政、经济、交通等核心地的功能产生严重影响。为此 ,文章注意到我国一些没有发现疫情的地区的地理条件 ,认为存在着如地理距离 (距离衰减 )、地理环境、产业特征等地理障碍。通过对这些障碍的分析 ,文章最后提出了防治疫情及其继续扩散的措施
[Abstract]:The rapid spread of SARS in China has had a great impact on the social and economic life of our country, and has provided us with a rare opportunity to observe and analyze the geographical diffusion. The spread of SARS is obviously a geographical process.The first characteristic of this process is the hierarchical diffusion as the way of development, the second is that it must encounter obstacles in the process of diffusion.The existence of the first characteristic makes the epidemic spread rapidly in our country for a period of time, but the spread of SARS is restrained under the condition of obstacle when various medical, isolation and protective measures are taken.This paper describes the mode of epidemic spread and the geographical pattern formed in China (with Guangdong and Beijing as the source). It is considered that the formation of this geographical pattern is related to the distribution of floating population and the conditions of population mobility in China.It is also pointed out that the high concentration in central cities is a worrying phenomenon in the geographical pattern of epidemic spread.This concentration has had a serious impact on the administrative, economic, transportation and other core functions of these central cities, including "medical centers."Therefore, this paper notes the geographical conditions in some areas where the epidemic situation has not been found, and considers that there are geographical obstacles such as geographical distance (distance attenuation, geographical environment, industrial characteristics) and so on.Through the analysis of these obstacles, the article finally puts forward the measures to prevent and control the epidemic situation and its continuous spread.
