摘      要：Land use generalization indices are critical for producing normative multi-scale land use databases and maps,but there is still not a national criterion for these indices in *** studies on land use data generalization indices often neglect macroindices such as area proportion of land use types and map load,and also ignore landscape effects on land use generalization *** we constructed an index system of land use data generalization from macro-and micro-perspectives,and examined scale and landscape effects on land use data generalization indices based on the countrywide multi-scale land use data *** formulated relationships between land use data generalization indices and both scale and land use pattern *** defined thresholds of land use data generalization indices on scales of 1:50000,1:100000,1:250000,and 1:*** verified our methodology and index thresholds through generalizing a county land use database.
