The veracity of land evaluation is tightly related to the reasonable weights of land estimate factors.By mapping qualitative linguistic words into a fine-changeable cloud drops and translating the uncertain factor conditions into quantitative values with the uncertain illation based on the cloud model,and then,integrating correlation analysis,a new way of figuring out the weight of land estimate factors is proposed.It may solve the limitations of the conventional ways.
