Abstract: By extending the traditional land suitability evaluation from natural conditions evaluation to land eco-economical 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 three classes: positive factor,negative factor and moderate factor.Based on these,the land eco-economical 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 results show that the model is reasonable and applicable.
