In order to improve the value of cultivated land resources and improve the policy of compensation mechanism for cultivated land protection,this paper takes Chengdu city,sichuan province as the research object.Based on the regional research scale of city-county-township and street,the value of cultivated land resources is measured from three dimensions of economic,social and ecological value,and its spatial distribution law is analyzed.The results show that:1.The comprehensive value of cultivated land resources per unit area in Chengdu is 33.2482 million yuan/hm2,of which the proportion of economic value,ecological value and social value is 17.15%,10.43% and 72.42% respectively;natural resources and geographical conditions determine the heterogeneity of the distribution of cultivated land resources in various districts and counties of Chengdu.The districts and counties located in the alluvial fan plain and the northeast and southwest regions have flat terrain,rich resources and high economic output;the distribution of cultivated land resources in towns and streets of Chengdu is closely related to its topography,climate and location.The value of cultivated land resources in towns and streets of Pidu district in the west of municipal district is higher,and the value of cultivated land resources in towns and streets of Jianyang city in the southeast hilly area is lower.
