With many new algorithms and new models coming forth,automatic cartographic generalization has made quite great progress in the past 40 years.As some experimental systems and a spot of commercial systems have contained some functions of automated generalization abroad,some software for automated generalization has been developed and used in China.But with in-depth study on this aspect,many scholars have realized that the automated generalization can't be achieved actually without quality control mechanism.Most automated generalization tools only provide basic parameter settings but can't control the quality of generalization at present.Therefore,on the basis of analyzing primary questions of automatic generalization at present,via embedded anatomy of current research status of automatic generalization quality assessment,main research contents and ideas needed for developing quality analysis and evaluating criterion of automatic map generalization are proposed.
