中文摘要：
距离衰减模型作为经典的定量模型已被广泛应用于多种学科的研究，本研究拟以该模型为理论依据，设计一套研究我国城市间网络服务器信息流传输随距离变化情况的方法．以中国教育科研网为对象，运用ping命令，获取国内各测试点之间的网络延迟时间（网络距离）资料，并运用GIS软件辅助测量工具，构建城市间网络距离衰减曲线，还可通过查取使用者使用密度和时间形态方面的信息、运用SPSS数学软件进行数据的离散性分析．
英文摘要：
As a classic quantitative model the distance decay model has been widely used in various branches of research. This study is baised on the distance decay model to design a method which can explor the changes of web sever information flows between Chinese cities. It includes： Using the CERNET as our study object,we use the PING program to obtain the network latency-a measure of network distance, and use GIS software to build the network distance decay curve between cities, we can further acquire of the using density and time of the networke users＇, and then use SPSS mathematical software for discrete analysis of the obtained data.
