摘要
植被地图综合是专题地图综合的一个特例 ,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 ;同时植被地图综合也要遵循植被分布自身的规律。该文主要研究和分析影响植被地图综合的主要规则 ,首先描述植被地图的特征 ,在此基础上分析讨论影响植被地图综合的主要综合规则 ,并简要介绍了用于表达综合规则的产生式规则方法 ,用实例描述了这些规则在植被地图综合各个阶段的应用和结果 ,以此来反映综合规则在植被地图综合过程中的重要性。
Vegetation map generalization is one of special cases of thematic map generalization. The generalization of vegetation map should be controlled by the generalization rules to solve the conflicts of map elements in smaller mapping space in order to keep map reasonable and clear. And the vegetation map generalization should follow the rules of vegetation distribution. The main subject of this paper is to discuss the rules which influence the vegetation map generalization and the application of these rules. The paper first depicts the nature of vegetation map, then introduces the basic concept of Production-Rule method for the representation of generalization rules. In the third section, the main rules of vegetation map generalization are analyzed in detail and some of them are represented with the Production-Rule method as examples. An example depicts the application of these rules and the results of generalization in the forth section. At last a conclusion part in the fifth section summarizes the contents of the paper and discusses the future works.
