【摘要】：文章以重庆主城区为例,从公共图书馆藏书量(供给)与街道(镇)常住人口(需求)的角度,引用随时间衰减的高斯两步移动搜寻法(Ga2SFCA),分别选取30分钟、60分钟作为最大搜索范围,对研究区域内的公共图书馆可达性进行研究。研究表明,重庆主城区公共图书馆的人均资源拥有量不高,图书馆的规模、附近人口规模、交通便利性对其供需情况有一定的影响;公共图书馆可达性分布不均衡,大体呈现以中西部为高值中心,向四周辐射递减的单中心环状结构,且随着时间阈值的增大,整体可达性有变好的趋势,但公共图书馆可达性分布的均衡性仍然较差。为合理提升和有效配置公共图书馆的资源,提出扩大高校图书馆开放力度和完善交通建设等建议。
[Abstract]:Taking Chongqing city as an example, from the public library collection (supply) and street (town) resident population (demand) angle, reference attenuation Gauss two step mobile search method (Ga2SFCA), were selected for 30 minutes, 60 minutes as the largest search range of accessibility of public library within the region. Research shows that the volume is not high with per capita resources in urban areas of Chongqing public library, the library scale, near the size of the population, traffic convenience had certain effects on the supply and demand situation; public library is uneven distribution, generally present in the Midwest for the high value center of radiation, single center ring structure decreasing to around, and with the increase of time threshold, the overall accessibility has a good trend, but the balance of the accessibility of public library distribution remains poor. In order to rationally improve and effectively allocate the resources of the public library, some suggestions are put forward to expand the openness of the University Library and improve the traffic construction.
