摘要: 从土地生态经济系统的角度,将土地适宜性评价看作是物种的最适生态位与评价单元所提供的现实生态位之间的匹配,从区域、评价单元以及单元之间关系3个层次构建评价指标体系,并引入模糊贴近度分析方法构建土地生态经济适宜性评价模型。以武汉市黄陂区为实例验证了模型的合理性。

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.
