The benefit of cultivated land use is an important measure of land productivity and sustainable agriculture development.By taking He'nan Province as the study area,19indicators were selected to build an evaluation index system of cultivated land use efficiency from the three aspects of economy,society and ecology.Entropy method was used to determine indicator weight;comprehensive multi-factor evaluation method,to evaluate the standards of cultivated land use efficiency from 1990to 2009;and the coordination degree model,to judge the mutual coordination degree for various subsystems affecting the cultivated land use efficiency.Results show that overall,the cultivated land use efficiency in He'nan Province presented an upward trend from 1990to 2009.The coordination degree of cultivated land use system was in an unstably fluctuated status in the 20years,from very uncoordinated status to basic coordination on a whole.To achieve a reasonable use of cultivated land resources in He'nan Province,we should exploit cultivated land use potentials,enhance land remediation and environmental protection,promote agricultural restructuring,develop agricultural science and technology,increase efforts to the concessions and support for agriculture,and control population growth.
