【摘要】 城市土地集约利用是指在城市规划、土地利用总体规划及相关法规的指导下,充分挖掘城市土地的利用潜力,实现城市和国民经济的可持续性发展。城市土地集约利用是当前建设节约型社会的需要,是缓解城市土地供需矛盾的重要课题。合理、有效地利用城市土地,需要对其潜力进行评价,以方便相关部门进行决策,达到城市土地集约利用的目的。因此,潜力评价方法的研究以及潜力评价系统的研发成为当务之急。本课题以城市土地集约利用潜力评价为研究对象,确定城市土地集约利用潜力评价方法和指标体系。并针对当前潜力评价中存在的问题和不足,研究城市功能区自动划分和现状与规划差异分析关键技术。在地理信息系统基本理论和空间数据挖掘技术的基础上,设计并实现了城市土地集约利用潜力评价系统。具体工作如下:分析和研究其它试点城市土地集约利用潜力评价的研究成果,确定城市土地集约利用潜力评价方法及指标体系,为潜力评价提供了依据;在功能区评价方法研究中,提出并研究基于自组织神经网络的功能区自动划分算法,有效地解决了传统手工划分的缺点;通过对空间数据库的分析,确定了土地利用现状与规划的差异性要素,实现了土地利用现状与规划的差异性分析,为城市土地集约利用发展提供可比的数据;设计并开发“城市土地集约利用潜力评价系统”,并对成都市的城市土地利用现状进行评价,获得了良好的效果,从而为不同城市的土地集约利用潜力评价提供了帮助。城市土地集约利用潜力评价系统是基于.NET和GeoMedia组件技术进行的设计和开发,具有实用性好、开放性强等特点,并为城市土地集约利用潜力评价项目的研究提供技术支持和决策支持。城市土地集约利用潜力评价成果的应用,对于推动城市存量土地潜力挖掘、提高城市土地供应和用地管理水平,起到了至关重要的作用。更多还原

【Abstract】 Under the guidance of urban planning and overall plan of land utilization and relevant regulations, Intensive Utilization of Urban Land (IUUL) is how to mine the potention of the urban land and implement the continuable development of the city and the country economy, which is also quite necessary to currently build the economical society and relieve the imbalance between supply and demand of the urban land.To use the urban land reasonably and effectively, it is necessary to evaluate the potention of the urban land, which is convenient for the government to make decisions.And finally, the aim of intensive utilization of the urban land will be achieved. Therefore, it is quite urgent to research on the methods of potention evaluation and develop the potention evaluation system.Potential Evaluation of Intensive Utilization of Urban Land (PEIUUL) is consideres as research object, and the methods and index system of PEIUUL is confirmed.To deal with the problems and the shortages of PEIUUL, this paper makes a research on the key technology of the auto-partition method of urban function regiones and the difference analysis between the parcel and the plan.Based on the theory of Geographic Information System (GIS) and the technology of Spatial Data Mining (SDM), the PEIUUL system is designed and implemented.The research work is as follows:According to the analysis and research on the results of PEIUUL of the other experimental cities, this paper confirms the methods and index system of PEIUUL, which provides the basis for PEIUUL project.During the reseach on the evaluation of the function region, the auto-partition algorithm is put forward, which is based on the reseach of the self-organization feature map. This method effectively solves the disadvantages of function region partition by hand.According to the analysis of spatial database, this paper confirms the difference-analysis elements of the urban land utilization between the parcel and the plan, and implements the difference anylysis, which provides the comparable data for the development of the IUUL.Design and develope the PEIUUL system.This paper makes an experiment on the parcel land of Chengdu, and ends with a good result, which is quite helpful for other cities to do the research on PEIUUL.Based on .NET and the COM technology of GeoMedia, the PEIUUL system is designed and developed with the characteristics of good practicability and strong openness, and provides the PEIUUL project with both technological and decision-making supports. The application of the results will promote to evaluate the potential of the remnant urban land, and improve the ability to supply and manage the urban land.更多还原
