The comprehensive evaluation of land intensive use based on coordination in Yichuan County

Aim To explore the level of land intensive use and the coordination degree of Yichuan County,in terms of land input intensity,land use intensity,output efficiency and sustainable use,so that the land intensive use could be improved properly.Methods Starting with the analysis of land economical and intensive use,the index system is established and the weights are determined by the method of AHP and Delphi.The original data are dealed to get the status of land intensive use and coordination degrees in Yichuan County through primary and secondary integrated evaluation,then the correlation between intensive land use degree and coordination degree is presented by the way of correlation analysis.Results The level of intensive land use and coordination degree of Yichuan County is quite low,but it keeps raising slowly;The index of unit land use can better reflect the intensive utilization of land use efficiency than per capita index;the intensive degree is highly positive correlated with coordination degree of its subsystems.Conclusion The government should raise the efficiency of current land use,transform the mode of farm land use,adjust and optimize the land use structure,develop laws and regulations and improve the land use mechanism to promote the intensive land use degree and coordination degree.
