【摘要】 土地是特殊的生产要素,随着我国市场经济的发展,地价已经成为我国政府重要的宏观调控手段。在城市化发展的进程中,实施土地集约利用是保护土地资源、实现城市土地合理配置的基本途径,也是实施可持续发展的必然要求。因此,研究城市地价的空间变化及演化规律,进行城市土地集约利用评价,分析城市地价和土地集约利用的关系,从而为土地管理和城市发展规划提供科学依据,引导城市土地经营向高效、持续、健康的方向发展,已成为当今值得深入探讨的研究内容。本文在GIS支持下,对基于GIS的城市地价与土地集约利用数据模型设计和数据库构建、综合地价模型构建的技术支持和实现方法、土地集约利用评价指标体系的构建、土地集约利用评价模型构建进行研究,采用GIS与专业评价模型相结合的方法进行土地集约利用评价,探讨了地价对土地集约利用的影响作用机制,并分析了二者之间的关系。主要工作和创新内容如下:(1)分析研究了城市地价与土地集约利用数据分层和数据组织方法,设计和建立基于Geodatabase的城市地价与土地集约利用数据模型;进行基础信息数据库、分析评价数据库、信息发布数据库和元数据库四位一体的数据库结构设计;对数据库建立和数据组织管理进行研究,探讨了不同类型数据间的快速访问及地价信息和土地集约利用信息的发布实现方法;最后对数据库建立的方法进行了研究,并建立了城市地价与土地集约利用数据库。(2)研究了综合地价模型构建方法,综合地价模型与GIS模型的耦合途径。分析了综合地价模型构建的技术支持,实现方法,构建了综合地价模型,进行了地价模型与GIS的耦合研究。验证模型的可行性,利用该模型对研究区域混合住宅用地和工矿仓储用地的地价空间结构和分布规律进行研究。(3)分析城市土地集约利用评价的标准,选取土地集约利用的评价指标,构建土地集约利用评价指标体系;探讨了GIS与评价模型融合的方案,构建基于GIS的专业评价模型和“多因素综合评价-系统聚类分析”模型,利用该模型对工矿仓储用地和混合住宅用地集约利用水平进行评价,并对评价结果和影响因素进行分析,科学公正地评价城市土地集约利用水平,对促进土地集约利用具有指导作用。(4)探讨了地价影响土地集约利用的作用机制,构建土地集约利用与地价实现水平的响应模型,在GIS技术支持下进行地价与土地集约利用的关系分析研究。提出要充分发挥地价对土地的利用量、投入程度和使用程度、利用效益等多方面协调作用,促进城市土地的集约利用。更多还原

【Abstract】 Land is a special productive factor. The land-value has been an important means for the macroeconomic regulation with the development of the market economy in our country. The intensive land use is a basic way to protect land resource and reasonably allocate urban land, and a requirement also for the sustainable development in the process of urbanization. The study of urban land-value spatial distribution and evolvement rule, and the evaluation of intensive land use, and the relation study of land-value and intensive land use have been important task in future. These studies will provide basic scientific data for land management and the city development planning. The study results will lead city development in an efficient, sustainable and healthy direction. According to the existing problems in the land-value spatial distribution and intensive land use, the paper proposes to study the land-value spatial distribution characteristics and the formation cause based on GIS technique; and evaluate the intensive land use by integrating GIS technique and special evaluating model; and analyze the relationship between land-value and intensive use in order to realize the affecting factors. The main study contents and innovations are as follows:(1) Design and construct a database of urban land-value and intensive use according to the system of study object, solve the update difficulty of the changing land-value and intensive use information, and implement integrative management and transformation of spatial data and attribute data in order to private the basic data with high quality for the study of land-value and intensive land use.(2) Apply spatial analysis technique in the study of urban land value. The sample data is analyzed with integrating exploratory spatial data analysis method and geostatistics method and construct digital land value model in order to efficiently obtain spatial land-value distribution and changing rule.(3) Select evaluation factors and construct factor system after analyzing the standard about intensive urban land use. Propose a scheme integrating GIS and special evaluation model and form and try to construct an integrative model by integrating multi-factor synthetical evaluation method and hierarchical cluster analysis method. Apply this integrative model on the industrial and residential land, and analyze the result of intensive use and influence factors in order to instruct intensive land use in the study area.(4) A positive correlation is found by analyzing relation between land-value and intensive land use level. We propose that land-value should be fully used to adjust the amount of land use, input and utilized level, and utilized benefit in order to promote the intensive land use.更多还原
