Abstract: In terms of land use zoning,requirements,a semantic similarity measurement model of geo-graphic entity is proposed.Methods for area balance and optimization evaluation are put forward forland use zoning partition results based on a study of the patterns of small polygons;a model of landuse zoning was constructed considering semantic similarity.These models are verified in a case study ofland use zoning in Haiwei,Changjiang county,Hainan province,China.The results show that theproposed methods provide a reasonable and efficient land use zoning model.Land use zoning schemesproduced by these models,not only can reflect human cognitive features but also can summarize landuse characteristics,and technically support land use planning and land use regulation and manage-ment.
