中文摘要：

自动综合总体上可分为两种模式,一种用来满足G IS的多尺度表达,另一种用于地图生产等。网络环境下的自动综合主要集中在对前一种模式的研究,而对如何依托网络优势进行面向地图生产的自动综合研究仍然很少,主要原因是面对复杂的自动综合,仍未找到合适的网络自动综合模型。本文在分析自动综合现状和发展趋势的基础上,提出了面向网络的＂黑匣子自动综合服务＂高级自动综合服务模型,论证了其可行性和不足,并对该模型进行了进一步的修正,提出了＂基于电子邮件的自动综合服务＂框架模型,该模型有效避免了其他模型的诸多缺点,同时具有成本低、稳定性高等优点。实例证明该模型的科学性和实用性,较好地适应了基于网络自动综合的地图生产。

英文摘要：

Automatic generalization might be divided into two kinds,one is for multi-representation of GIS,and the other is for map making.In the past decades,the first kind is researched mainly,while the later one is seldom touched.With the development of internet,the research on web generalization is but still restricted only for rapid multi-representation of GIS,because automatic generalization is very complex and it is difficult to find a suitable web generalization model for web map making.After analyzing the development and disadvantages of automatic generalization and getting suggestion from Service-Oriented Architecture（SOA）,WFS and WMS and so on,this paper put forward a web generalization model termed＂dark-box oriented automatic generalization service＂.Then,by discussing the feasibility and shortcomings of this model,a more advanced automatic generalization model called＂Email-Oriented Generalization Services（EOGS）＂architecture was developed in this paper,which could avoid many disadvantages of previous generalization models.Furthermore,EOGS model owns many advantages such as low cost and high stability etc.Example illustrated that EOGS model would make web-based automatic generalization map making fully satisfied.
