中文摘要：

基于GIS的软件开发专业性强且难以掌握，GIS的软件项目开发周期长、难度大并且系统维护困难，针对这一系列问题，本文提出了GIS构件仓库的概念，指出了GIS构件仓库与传统构件库的区别，给出了GIS构件仓库模型，实现了构件可视化复合与GIS应用系统的快速搭建。

英文摘要：

In order to resolve some deficiencies of GIS such as long period, difficult development and maintenance, a concept named GIS component repository is proposed. The difference between GIS component repository and traditional component repository is pointed out. A model of GIS component repository is given. Visual component composition has been realized. The application of GIS can be quickly constructed based on the model.
