摘要
土地整理是按照可持续发展的原则,对耕地、道路、林网、居民点、水利设施等进行综合整治,调整土地利用结构和土地覆被的行为。土地整理立项决策是土地整理全生命周期项目管理的一个重要环节。针对决策过程中普遍存在的对象属性过于复杂的特点,论文通过二元关系理论刻画了评价对象不依赖于连通性的重要特征,并以此构建其格序结构。提出了采用属性约简的方法分析优势关系,基于优势基和差异度的概念逐步简化决策规则,判断约简前后格序结构的相对贴近程度和约简规则的合理性。论文最后以东南沿海区及黄土高原区典型土地开发整理项目为例,根据"市场与社会需求程度"、"技术可行性"、"建设规模合理性"、"项目效益"等指标,对其立项合理性进行评价。研究表明,属性约简结果可视为最初格序结构的一个线性扩张,是评价集合中的部分不可比元素在其偏好决策空间中的一个投影形式,其形成反映了属性约简规则的逐阶段选择过程,体现了决策者的知识水平和思维背景发展水平。
Land consolidation is one of the integrated measures to adjust land use structure and land cover, through improving the condition of land, road, forest, residential spots, water conservancy facilities, etc. project determination is the key stage through the process of land consolidation project management. For the purpose of analyzing complex attributes, binary relation theory is employed to discuss the interrelation of assessed objects and corresponding lattice structure is construct, which particularly depicts the an-connectedness. Attributes reduction approach is proposed to analyze advantage relationship and simplify the decision-making rules. In the advised model, the conceptions of advantage base and diversity degree are used to explain the reasonableness of attributes reduction rules for lattice structure. Finally, a case study of land consolidation project approval, both in southeast coastal region and the Loess Plateau region, is carried out. In the case study, four indexes are focused, requirement from market and society, technical feasibility, construction scale and engineering benefit. The results show that, attributes reduction can be considered as one linear extension of original lattice-order structure and is the projection in preference space of non-comparative objectives. The generation process implies choosing procedure of attributes reduction rules. It also is used to illustrate the knowledge and thought level of decision-makers.
