“数字小区”是“数字地球”的微观表现，是“数字地球”某一小区的“放大”效果，是数字化的虚拟的小区。根据“数字地球”的理论和战略，提出了“数字小区”的概念，为结合“数字地球”相关技术及三网合一、智能小区、智能住宅系统、等来构建和实现“数字小区”还探讨了“数字小区”总体结构、物理基础设施模型体系，关键技术和集成应用，最后提出实现“数字小区”的研究方法和建设思路。

Digital mini\|area is the microcosmic description and reification of the digital earth and can be simply defined as a digital and virtual small area in concept. Based on the theory and strategy of Digital Earth, the concept of Digital Mini\|area is proposed. To develop and establish a digital mini\|area with the related technologies of the digital earth and such technologies as three\|in\|one integrative network system, intelligent mini\|area, intelligent house system and digital neural system, the general structure, the physical infrastructure, the network structure, the information structure, the function structure, the model structure, the key technologies and the integrative applications of Digital Mini\|area are then discussed. At the end, some methods and guidelines on how to develop the digital mini\|area are also given out.
