【摘要】 农用地分等数据库的综合属于GIS专题数据综合的研究范畴,需要遵循地理数据综合规则,以解决因表达空间缩小而造成的地物要素间的冲突问题,确保图面上图形表达的合理、清晰和美观;同时也要遵循农用地质量分布的自身规律。本文主要研究和分析影响农用地分等数据综合的主要规则,首先从较为普遍的角度分析了影响专题数据综合的综合规则,然后分析农用地分等省级汇总工作需研究及解决的问题,在此基础上以湖北省农用地分等为例,分析了农用地分等数据库综合的主要规则。更多还原

【Abstract】 Generalization of agricultural lands database is important component of thematic database generalization in GIS.The generalization of agricultural lands database should be controlled by the generalization on rules to solve the conflicts of map elements in smaller mapping space in order to keep map reasonable and clear.And the generalization of agricultural lands database should follow the rules of agricultural distribution.The main subject of this paper is to discuss the rules which influence the agricultural land database generalization and the application of these rules.The paper first depicts the generalization-rules from the view of general point,then resolved the main point about provincial classification of agricultural lands.On the base,the main rules of agricultural land database generalization arc analyzed in detail,classification of agricultural lands on Hubei province as examples.更多还原
