主　　题：Wuhan Metropolitan Area Cultivated land resource Ecological service value 

摘      要：The land ecosystem service function value contains the gas regulating function value, air purification function value, water conservation value, land conser-vation value, soil nutrient conservation value and maintain biodiversity value. Based on the method of market value and the data of Hubei Statistical yearbook, cultivat-ed land resources of ecosystem service function value is 730 038.69Mil ion in 2007-2009, and 714 774.99 Mil ion in 2010-2012 in Wuhan Metropolitan Area. After three years of development, Wuhan Metropolitan Area of ecological value of cultivated land has increased by about 3.97%. From the point of each composition, the im-portance of gas regulating function of cultivated land resources and water conserva-tion function is the forefront. From the point of spatial distribution, the highest of annual average value of the cultivated land ecological was Huanggang （1.725 bil ion yuan）, the lowest was Ezhou （217.868 6 mil ion yuan） in 2010-2012. From the point of space changes, the land ecological value increased only in Qianjiang city, while farmland ecological value in other cities was fal ing The conclusion is of direc-tive significance to the regional land protection policy and the farmland reasonable distribution, for Wuhan Metropolitan Area and other areas.
