摘　　要：研究了零散多边形综合的质量评价,采用定性和定量相结合的方法,通过描述要素特征确定各要素特征的评价指标,然后整合各特征评价结果,得到地图综合的整体质量评价结果。以土地利用图中的农村居民点综合为例,介绍了其质量评价的过程,验证所提方法的可行性。The evaluation and guarantee of the quality of automated map generalization is recently a hot point at home and abroad.We mainly study on the quality assessment of scattered polygons.In order to get the final assessment of the whole cartographic area′s generalization,we propose a method containing both qualitative and quantitative ways.According to the criterion of some critical indices of features,this method begins with the presentation of these indices.By comparing with the criterion,every feature will have a specific assessment result for its generalization.After integrating all the results,we can get the final assessment of generalization.At last,taking the generalization of rural settlements as an example,we introduce the process of quality assessment in detail,which has been proved to be feassible.
