Based on the method of market value and the data of Hubei Statistical yearbook, cultivated land resources of ecosystem service function value is 730 038.69 Million in 2007-2009, and 714 774.99 Million 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 importance of gas regulating function of cultivated land resources and water conservation 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 billion yuan), the lowest was Ezhou(217.868 6 million 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 falling The conclusion is of directive significance to the regional land protection policy and the farmland reasonable distribution, for Wuhan Metropolitan Area and other areas.展开更多

Their internal relationship is manifested as agricultural structure suits demand of urbanization development through adjustment in the process of urbanization,while urbanization is based on development of regional agriculture. From history of world agriculture and urbanization development,agriculture firstly provides primitive accumulation for urbanization development,and drives regional urbanization through promoting agricultural development. When urbanization develops to certain stage,urbanization accumulation increases and reaches the goal of " boosting urbanization through agriculture". If urbanization develops slowly,agricultural adjustment will lack motive force. On the contrary,weak agricultural development will lead to stagnation of urbanization. Therefore,adjustment of agricultural structure and urbanization development are interconnected,mutually promoted and restricted,and interdependent.展开更多
