Abstract：Metadata is one of key technology of constructing Digital Earth,and a main solution of implementing spatial information sharing in Digital Earth.This research concentrates on design and implementation of a metadata management system of grading,classifying and pricing cropland(CLMDMS).Firstly,the content of metadata of gradation,classification and price of cropland is pointed out based on normal conception of metadata.Then,CLMDMS is described and designed using Extensible Markup Language(XML) technology.The function module of CLMDMS is realized with Visual(C#.) Finally,the realization process of CLMDMS is discussed.So,the research results are important for standardization,unification and communion of information in both theory and application fields of land management.
