This paper uses the decoupling analysis method to analyze the status, degrees and causes of decoupling of cultivated land occupation by construction from economic growth in the period of 1993 to 2006 in Chengdu city, and hopes to provide the government with relevant measures of the decoupling of cultivated land occupation by construction from economic development. The results are as follows: 1) Relative decoupling and absolute decoupling of cultivated land occupation by construction from economic growth occurred at 57.14 percent in the research period. However, the degrees of decoupling had obvious variations in the temporal scale; 2) The elasticity values of the decoupling exhibited an inverted “V” shaped curve; 3) The additional investment of capital and labor, the implementation of government policy and measures, the pattern transformation in the economic growth will help accelerate decoupling. Therefore, the quantity of cultivated land occupation by construction should be under the control of Chengdu government, meanwhile, the government need to speeding up the transformation of economic development models and optimizing the structure of industry so that cultivated land conservation and economic growth are not a dilemma.
