摘要： 为了验证模糊模型识别法对土地整理项目进行综合效益评价的可行性，从社会、经济、生态3个方面构建土地整理综合评价指标体系，对格尔木市大格勒乡土地整理项目的评价指标量化，利用文献综述法建立模型识别库，根据模型库正态分布数据原理确定隶属函数，建立评价体系与综合效益等级关联度模型。结果表明：格尔木市大格勒乡项目属于“好”级别；乌图美仁乡与郭勒木德镇属于“一般”级别；造成以上级别差异的主要原因是权重较高的社会效益显著性过低，符合项目区实际情况。实例研究证明，基于模糊模型识别法建立的理论和方法在土地整理综合效益评价具有科学性和可操作性。

Abstract: In order to verify the feasibility of the method of fuzzy model recognition for the integrated benefit evaluation of land consolidation project, the author firstly constructed the comprehensive evaluation index system of land consolidation from three aspects, which were the social evaluation, the economic evaluation and the ecological evaluation, to make the evaluation quantization of land consolidation project in the Greater Grenoble Township in Golmud City. Then, the paper used the literature summarize method to establish the model recognition libraries ,and based the principle of normal distribution data in the model libraries to determine the membership function, to build the evaluation system and the grade correlation model of comprehensive benefit. The results showed that the project in the Greater Grenoble Township in Golmud City belonged to a level on ‘good’, the Ukraine map Meiren Township and the gol Wood German Town belonged to the ‘general’ level. The main reason for differences in levels was due to that the higher weight in the significant resistance of the social benefits was too low, which was in accordance with the actual situation of the project area. The case study indicated that the theory and the method based on the method of model fuzzy recognition on the comprehensive benefit evaluation of land consolidation had the scientificalness and operability.
