By extending the traditional land suitability evaluation from natural conditions evaluation to land eco-economic comprehensive suitability evaluation, the evaluation factor system is created from three levels, which are regional level, unit level and inter-unit level. Meanwhile the quantitative criterion and methods are developed from four classes: positive factor, negative factor, moderate factor and qualitative factor. Based on these, the land eco-economic suitability evaluation model is proposed on the basis of fuzzy close-degree analysis. In the end, Huangpi district of Wuhan city is taken as an example to have a case study. The result shows that the model is reasonable and applicable.
