摘要

土地整理经济效益分析是土地整理的一项重要内容。把可拓学理论和方法应用到土地整理工程中

建立土地整理经济效益经典域物元、节域物元和待评物元模型

借助可拓方法中距

建立了关联函数模型; 通过简单关联函数计算指标的权重值

建立各指标与标准等级的综合关联度模型

将关联度值进行加权处理

得到加权关联度值

并进行规范化处理

得到综合关联度值

然后计算出评价等级值。将该方法应用到实际项目中

计算该项目的经济效益等级值为2.204

属于“良好”级别。实例研究证明

基于可拓学的理论和方法建立土地整理项目经济效益评价模型具有科学性和可操作性

拓展了土地整理项目效益评价方法体系

取得了良好的效果。

Abstract

Analysis of the economic benefits of land consolidation is an important content of land consolida-tion. With an attempt to apply extension theory and method to land arrangement project

the models of clas-sical field matter element

controlled filed matter element and evaluation matter element are constructed for the economic benefits of land consolidation.The incidence function model is also established using the exten-sion method of distance. A comprehensive correlation degree model for evaluation index and standard grade is then established based on the simple correlation function calculation of index weights. Finally

weighted pro-cessing is adopted for the correlation values and a series of weighted correlation values are obtained. The weighted correlation values are normalized to get average correlation values. When the method is applied to the actual project

the grade for the calculated economic benefits is 2.204

being in a "good" level. The re-search proves the scientific and practical nature of the evaluation model for land arrangement project benefits based on the theory and method of extenics and provides a new approach to the quantitative evaluation of land consolidation economic benefits with a good result.
