<正>探讨了“数字区域”市情数据的集散理念，提出了一种基于WebGIS的Web服务技术的“数字城市”市情数据库集散平台框架。以四川省宜宾市为例，基于Geodatabase空间数据库模型，对分散、自治和异构的市情数据进行整合，以web服务实体的形式组建集散平台，达到快速提取和集成市情数据的目的，并充分模拟系统的真实运行环境，检验了系统最终运行效果。

The paraffin cut method was used to observe the morphological differentiation process of the flower bud of Osmanthus fragrans ’Wanzi Yingui’ and ’Duoya Jingui’. The result showed that the flower bud differentiation process lasted for about 3 months from bract primordial differentiation in the end of June to pistil primordial formation in the beginning of September. The morphological differentiation of osmanthus flower bud was divided into seven phases: bract differentiation phase, inflorescence primordium differentiation phase, single flower primordial differentiation phase, sepal differentiation phase of top flower, patal differentiation phase, stamen differentiation phase and pistil differentiation phase. The phase of bract differentiation and stamen differentiation were relatively long. The top flower of the inflorescence differentiation was earlier and slower than the lateral flowers. Later on all the top and lateral flowers finished differentiation almost at the same time. The prophase bud differentiation of ’Duoya Jingui’ was the same as ’Wanzi Yingui’ except for pistil differentiation.
