摘要
利用物元分析理论,将土地整理综合效益的等级、评价指标及其特征值作为物元,确定土地整理综合效益的经典域、节域及待判物元,应用物元和可拓集合中的关联函数建立了土地整理综合效益物元评判模型。并以山西省阳高县王官屯等二乡(镇)土地开发整理项目为例,对土地整理综合效益物元评判模型进行了实证研究,其综合效益的等级属于程度Km(P)=(-0.101,0.037,-0.431),属于"一般"等级,与模糊综合评价结果相似,符合项目区的实际情况。物元模型应用于土地整理综合效益评价作为一种初步的尝试与探索,为定量评价土地整理综合效益提供了一种新的思路。
On the basis of matter element analysis theory,the grade,evaluation indicators,and characteristic values of comprehensive land consolidation benefit are taken as matter elements and then the sutra field,controlled field,and matter element for judge are determined.A matter element judge model for comprehensive land consolidation benefit is established using correlation function of extension set and matter element.The model is applied to land consolidation projects in Wangguantun and Xiajingshen Towns,Yanggao County,Shanxi Province for a case study.The grade of comprehensive benefit belongs to degree Km（P）=（-0.101,0.037,-0.431）,being a general grade,and it has a result similar to fuzzy comprehensive evaluation and accords to the conditions of project area.It is an attempt that matter element model is applied to evaluate comprehensive benefit of land consolidation.A new idea is provided for quantitative evaluation of land consolidation comprehensive benefit.
