【摘要】 随着我国经济的快速发展和城市化进程的加快,城市土地利用的问题和矛盾也日益突出,主要体现在城市土地利用结构不合理、土地利用强度低、城市环境质量不断恶化等方面。城市土地集约利用评价是促进城市土地合理利用,提高城市土地利用效率,改善人们生活环境,实现土地资源可持续发展的重要手段。近年来,遥感(RS)、地理信息系统(GIS)和计算机技术的快速发展与应用为实现城市土地集约利用评价提供了新的方法和技术手段。本论文以唐山市高新区的城市土地利用现状数据为基础,基于城市土地集约利用的理论方法,借助于RS、GIS、网络及计算机等技术,取得了如下成果:(1)为研究区建立了综合评价指标体系,选取了综合评价模型。(2)基于GeoDatabase模型建立了土地利用专题空间数据库。(3)采用.NET语言和GIS组件技术,设计开发了B/S、C/S混合构架的城市土地集约利用综合评价系统(ULAIS),实现了城市土地利用管理和集约评价的信息化、科学化。(4)利用研制的ULAIS系统,完成了唐山市高新区城市土地的现状和集约利用评价。通过评价分析发现:该区建设用地配置比较合理,农用地比例较大,商服用地较少,工矿用地偏高;土地利用强度偏低,全区建设用地建筑密度为0.31,建筑密度小于0.15的宗地面积占宗地总面积的31.8%,建筑容积率为0.61,建筑容积率小于0.5的宗地面积占总宗地面积的60.3%;土地集约利用偏低,建设用地中低度利用的比例为38.8%,过度利用的占6.4%。城市土地利用强度偏低,具有很大的挖潜空间。本研究不仅为唐山市高新区的土地集约利用评价提供了理论依据和技术手段,其建立的指标体系和评价系统对其他城市的土地集约利用评价研究也具有较大的实践价值。更多还原

【Abstract】 With the rapid development of economy and acceleration of urbanization process in China, problems and conflicts of urban land using are becoming increasingly prominent, mainly including unreasonable urban land using structure, low intensity of land utilization, continuously deteriorating quality of urban environment and so on. Assessment of intensive use of urban land play an important role on promoting the rational use of urban land, improving the efficiency of urban land use, improving people’s living environment and realizing sustainable development of land resources. In recent years, the rapid development and application of Remote Sensing (RS), Geographic Information Systems (GIS) and computer technology offers new methods and technical means to achieve intensive use of urban land. Based on the urban land-use status data of Gaoxin District in Tangshan City and the theory and method of intensive use of urban land, this paper achieved the following results by means of RS, GIS, Internet and computer and other technologies:(1) Established a comprehensive assessment index system and selected a comprehensive assessment model for the study area; (2)Established a thematic spatial database of land use based on GeoDatabase model; (3)Designed and developed an Urban Land Assessment Information System (ULAIS) of compound framework(hybrid structure) of B/S and C/S by using of“.NET”language and GIS component technology, which achieved the informatization and scientization of the management and intensive assessment of urban land; (4)Completed the assessment of present situation and intensive use of urban land in Gaoxin District of Tangshan City by using the developed ULAIS system. Through the assessment and analysis, some conclusions can be drawn as follows: firstly, the distribution of construction land of the study area is reasonable, which is proved by large proportion of agricultural land, small proportion of business and services land, high proportion of industry and mining land; secondly, land use intensity is low; the building density of whole area’s construction land is 0.31, the land area of building density which is less than 0.15 accounts for 31.8% of the total land area; building plot ratio is 0.61, the land area of building plot ratio which is less than 0.5 accounts for 60.3% of the total land area; thirdly, intensive use of land is low, the proportion of low and moderate use of construction land is 38.8% and overuse accounts for 6.4% and there is a lot of potential developing space.This study not only offers the theoretical basis and technical means to assessment of land intensive use of Gaoxin District in Tangshan City, its established index system and assessment system also has great practical value for the assessment study of land intensive use to other cities .更多还原
