中文摘要：

针对城市部件调查与质量检查的繁琐与复杂性,提出了利用地理信息技术（GIS）与数据库技术,在GIS软件及其建模模块中实现城市部件点的矢量检查、逻辑性检查、点对称性与连续性检查、属性检查中唯一性检查、非空检查、匹配检查与属性名称逻辑性检查。研究结果表明：通过部件质量检查的模型建立及实现对部件调查与检查有很强的适用性。该研究结果对于城市部件调查具有非常好的理论意义和实践价值。

英文摘要：

To mitigate the complexity of urban component investigation and quality inspection,this paper proposes that the vector-point inspection,logic checking,symmetry and continuity checking of urban components points are implemented based on the GIS modeling module.Also the uniqueness checking,non-empty checking,match checking and logic name checking of component attributes checking use the same GIS technology.The study shows that the GIS technology is suitable for the quality inspection modeling,components investigation and inspection.This study provides a very good theoretical and practical reference for urban components investigation.
