就现代计算机软件技术发展的若干方面进行了回顾和分析，结合GIS软件在这些方面的实现进行了讨论，特别就GIS软件在空间数据的分布式计算，空间数据，属性数据的一体化查询与操作，空间数据挖掘等方面进行了比较深入的分析，指出目前GIS实现技术存在的不足及其原因，主要表现在空间数据模型的组织和存储技术不完善，缺乏完整空间关系描述框架，以及空间数据与其他数据联系不够紧密等方面。提出了解决这些问题的技术突破方向，是要改变以图层为基础的空间数据存储和操作模式，建立空间同步的数据操作机制，实现空间数据修改的UNIX语义，要研究空间数据与属性数据一体化查询语言，提出空间数据的操纵能力，等等。

In this paper,some modern computer software techniques are introduced. However, those techniques can not be put into practice of GIS software design. Especially, spatial data distributed computation, combining query and operation of both spatial and attribute data are focused on. In this paper. The weaknesses of GIS implementation technique, like the spatial data modeling and storing, the completed framework of spatial relationship and declaration, the relationship presentation between the spatial data and the attributes are pointed out. Also, the technical directions to solve those problems are presented. The layer-based spatial data storing and operation model has to be changed. The synchronization mechanism of spatial data operation has to be established. The UNIX semantics of spatial data modification has to be implemented. The GSQL has to be researched so that the ability of spatial data administration can be increased. etc.
