Abstract The authors systematically identify and classify land use functions based on the system theory, and then construct the multi-scale and multi-level evaluation index system of land use functions from three aspects of economy, society and ecology from the perspective of patch scale. A preliminary attempt is made to obtain and spatialize index data. The results show that land use functions has multiple levels and regional characteristics, corresponding classification and evaluation index system should be established according to different regional background and research scale. Land use functions are related to land use structures, and its evaluation scale is extended to the micro-scale, which is helpful to expand the scope and enrich content of the study of land use functions. Key words land use functions; system theory; classification and evaluation; index system; multi-scale
