This paper chooses 2000 stochastic retailing stores whose acreages all exceed 40km2 in the three circles of Wuhan city,after the analysis of spatial difference on acreages,number,population density,and manage forms,and makes a conclusion that the retailing spatial structure of Wuhan city has taken on figure of ring shape with hierarchy wholly and frame of centralization-diffusion and enchasing partially; Finally,the whole paper probes into the change mechanism and trends of retailing spatial structure.

随机抽取武汉市中环线内2000个营业面积大于40m2的零售商业网点，基于统计资料、实地调查，运用GIS空间分析技术，划分环带与格网提取武汉市零售业网点密度、服务人口、营业面积、业态分布、商品特色等空间分布数据，分析零售业网点密度分布的空间特征，得出武汉市零售业在空间结构上表现出整体的等级圈层结构，局部的空间聚合扩散结构和&逆发散特征&——镶嵌结构；最后对其变动的动力机制和演变趋势进行了初步探讨。

Therefore, the compulsory education should be adjusted to education of free tuition, while the non-compulsory education should be imbursed by the cooperation between government and social capital; corporation administration structure should be established and perfected and genuine institution of credit transformation and credit bank should be established.

Study limitations include attrition rate of 20% at one month and 36% at six months; study completion beyond the originally intended six-month timeframe in 75% of participants; reliance on self-reported behaviors; exclusion of potential participants if they lived in a foster-care or group home; lack of generalizability beyond urban, predominantly minority, low-income young women and to women who are not sexually active; unknown impact of repeated interviews on sexual or contraceptive behaviors; and lack of statistical power to detect differences in secondary outcomes.

这项调查原本预计75%样本数可延续观察六个月，然而，此研究受限因素包括一个月期的耗损率为20%，六个月期的耗损率为36%。这些限制来自于自发性主动陈述行为的难处、排除被领养的样本群、都会区人口流动性及整体性不佳、少数民族为主、多为低收入青少女、另有些性行为并不频繁、以及其它未知的相关因素；另外，也缺乏有力的统计方式，以进一步判读不同族群间的差异。
