| 中文摘要: |
| 在全面分析和归纳影响空间数据库质量主要因素的基础上，提出了基于领域知识，从元数据、图形拓扑关系、属性、图属关系等方面袁建立空间数据库质量描述的规则库，构建通用的空间数据库质量检查模型，以提高空间数据库质量的检查效率。利用该模型开发了开发区土地集约利用评价数据库质量检查系统，有效保证了开发区土地集约利用评价数据库的质量。 |
| 英文摘要: |
| Based on the systematical analysis and induction of the main factors which affect spatial database quality, the paper
proposed that the rule library and the common quality checking model were built according to domain knowledge, metadata, topological relation, attribution and the relation of geometry and attribution for improving the checking efficiency of spatial database. On this basis,the database checking system for evaluation of land intensive use was developed to effectively control the database quality of evaluation of land intensive use. |
