This study on the basis of analysis of land use background and current situation of Fujian Province , to follow certain scientific principles , and build a comprehensive evaluation index system of land use benefits , were dynamic changes of land use efficiency in Fujian Province from 1997 to 2007 , 2007 , 9 , with districts City land use efficiency differences to evaluate analysis ; to establish barriers degree determination model , effective barriers to factor affecting land use to make a diagnosis and in-depth analysis . The results show that : ( 1) from 1997 to 2007 , Fujian Province, the land use comprehensive benefits increase every year trend of and growing faster growth , each sub -effective , economic, social , and comprehensive benefits trends , eco-efficiency is rise in volatility ; (2) land of the nine districts and cities in Fujian Province in 2007 with comprehensive benefits overall level is not high, the obvious regional disparities and land use comprehensive benefits and levels of economic efficiency are closely related , social and ecological benefits important effect ; ( 3 ) , Fujian Province of land use efficiency space differentiation significantly southeastern coastal region as a whole seems better than other areas of the province ; (4), Fujian Province, the municipalities and districts , the majority of municipalities and districts land the use of effective dominant obstacle factor to economic factors , social and ecological factors are involved , is based on the ecological factors in the social and economic well-developed Xiamen City . Finally, the proposed land use optimization strategies based on land - effectiveness .
