【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。
[Abstract]:According to the principle of sustainable development, land consolidation is a comprehensive management of cultivated land, roads, forest networks, residential areas and water conservancy facilities, and the behavior of adjusting land use structure and land cover. Land consolidation project decision is an important link in the whole life cycle project management of land consolidation. In view of the fact that the attributes of objects are too complicated in the process of decision making, this paper describes the important characteristics of independent connectedness of evaluation objects through the theory of binary relation, and constructs its lattice order structure. The method of attribute reduction is proposed to analyze the advantage relationship. Based on the concepts of superiority basis and difference degree, the decision rules are simplified step by step, and the relative closeness of lattice structure before and after reduction and the rationality of reduction rules are judged. Finally, taking the typical land development and consolidation project of southeast coastal area and loess plateau as an example, according to the index of "market and social demand degree", "technical feasibility", "construction scale rationality", "project benefit" and so on. The rationality of the project is evaluated. It is shown that the result of attribute reduction can be regarded as a linear extension of the initial lattice order structure and a projection form of some incomparable elements in the evaluation set in its preference decision space. Its formation reflects the process of selecting attribute reduction rules step by step, and reflects the level of knowledge and the development of thinking background of decision makers.
