【摘要】：土地问题,在中国历史上向来就是一个核心问题。随着土地制度改革的日趋完善、规划理念变革的日益成熟,我国土地利用发展也更加合理与高效。但是因为规划存在滞后、效益理念存在差异以及土地使用状况的评价系统不成熟,导致土地利用依然存在诸多问题。如用地结构不合理,土地利用效率低下,违法占用耕地等。为此应该适应转变政府职能、加强监管,及时发现并改进土地利用过程中的问题,就有必要必要针对土地利用状况进行信用评价研究。文章首先分析了我国土地利用信用研究现状,交代了背景。其次参考相关领域国内外学者有关信用评价指标体系和评价方法的研究基础上,同时考虑当前我国土地利用过程中的实际问题,即因地制宜,研究包括建立土地利用信用评价指标体系以及构建土地利用信用评价模型两大方面内容。在建立评价指标体系方面,从土地利用的影响因素着手,围绕指标体系的确立原则,从定性指标和定量指标两个方面建立土地利用信用评价指标体系。然后根据所建立的指标体系,搜集25个样本地方的相关数据,并通过相对客观的熵权法计算确定各级指标权重以及验证所选信用评价模型的基础数据;在构建土地利用信用评价模型方面,最初分别运用灰色关联投影模型、模糊积分法建立了土地利用信用评价模型,并对样本数据进行实证分析。在对比评价结果的基础上,选取组合评价法对评价模型进行优化。最后运用优化后的评价模型对样本数据进行实证分析,以此验证所建立的土地利用信用评价指标体系以及评价模型的合理性和可行性。
[Abstract]:The land issue has always been a core issue in Chinese history. With the improvement of land system reform and the maturation of planning concept, the development of land use in China is more reasonable and efficient. However, there are still many problems in land use because of the lag of planning, the difference of benefit concept and the immaturity of land use evaluation system. If the land structure is unreasonable, land use efficiency is low, illegal occupation of cultivated land and so on. Therefore, it is necessary to study the credit evaluation of land use by adapting to the transformation of government functions, strengthening supervision, and timely discovering and improving the problems in the process of land use. This paper first analyzes the present situation of land use credit research in China and explains the background. Secondly, on the basis of the research on the credit evaluation index system and evaluation methods of domestic and foreign scholars in related fields, and at the same time considering the actual problems in the process of land use in our country, that is, according to the local conditions, The research includes the establishment of land use credit evaluation index system and the construction of land use credit evaluation model. In the aspect of setting up the evaluation index system, the evaluation index system of land use credit is established from two aspects: qualitative index and quantitative index, starting with the influencing factors of land use and the principle of establishing index system. Then, according to the established index system, the relevant data of 25 samples are collected, and the relative objective entropy weight method is used to calculate and determine the index weight at all levels and verify the basic data of the selected credit evaluation model. In the aspect of constructing the land use credit evaluation model, the grey correlation projection model and the fuzzy integral method are used to establish the land use credit evaluation model at first, and the sample data are analyzed empirically. On the basis of comparing the evaluation results, the combined evaluation method is selected to optimize the evaluation model. Finally, an empirical analysis of the sample data is made by using the optimized evaluation model to verify the rationality and feasibility of the established land use credit evaluation index system and the evaluation model.
