Abstract: [Objective]This paper evaluates the cultivated land ecological security situation and the economic development state of Fujian province in recent years respectively,and analyzes the coordination between the two system. [Methods]This paper uses the entropy weight method to determine the weight of indexes,the multi-factor comprehensive evaluation method to analysis the condition,and the coordinated development model to get the coordination degree and the coordinated development degree of the two systems.[ Results] Results show that: (1) From 2004 to 2015 ,the cultivated land ecology value in Fujian province was high in general, and it has a further enhance after the 18th national congress of CPC puts forward the construction of ecological civilization,and at the same time ,the economy keeps a rapid and stable increasing speed.
