浅谈铁路建设项目竣工建设用地验收交接

在铁路新线建设和既有线扩建改造中,新征用地的手续完备及形成时间的早晚,不仅关系到工程进度,而且对工程竣工验交后铁路用地管理及使用都至关重要。因此,铁路用地管理部门超前介入铁路新线建设和既有线扩建改造,参与铁路建设项目建设新征用地的全过程,已成为铁路用地管理部门需要研究的课题。     

推行内部土地使用证 加强铁路用地管理

铁路是国家的重要基础设施,是国民经济的重要基础产业部门,是国民经济的大动脉,在国家综合交通体系中起着重要的骨干作用。而铁路用地,是铁路运输生产的重要基础,是维护铁路运输安全的重要条件,是铁路经营的重要资产,是铁路改革发展的重要资本。铁路用地资产量庞大等特点,决定了铁路用地管理工作是铁路改革发展的重要组成部分,因此,加强铁路用地管理,推行铁路局内部土地使用证,是有效发挥土地管理为铁路改革和发展提供保障和服务的有益探索。     

铁路用地的特性与管理方式

铁路用地是铁路运输生产的物质基础和运输设施的组成部分,直接关系着铁路运输安全和改革发展的大局。随着铁路生产力布局的调整和管理关系的转变,尤其是铁路新干线、新网络的快速发展,对铁路用地管理提出了更高的要求。如何加强新形势下铁路用地管理,是摆在我们面前的新课题。     

铁路用地地籍管理技术方法及相关问题研究

随着地籍管理科技发展,铁路用地地籍管理在引入国家大地统一坐标系的测量技术手段的同时,为满足铁路用地线状分布特点和Et常管理的需要,仍然保留了独立坐标系统。而铁路运营设备的不断更新和技术装备的不断提高,铁路线路设备发生了较多拨移、变线或改道,作为确认铁路地界线位置的基准线,铁路线路的变化,对快速准确地查找铁路地界线产生了直接影响。为此,针对铁路用地参照坐标的变化情况及调整方法进行了深入调查研究,提出了可行性建议。     

铁路土地管理的浅层思考

随着我国改革开放的深入、市场经济地位的确立,全国铁路也正在进行着跨越式的发展：列车提速、高铁建设、主辅分离、社会化职能移交、铁路公检法的属地化管理等等。在改革进程中,也出现了一些新的问题与矛盾,对当前铁路用地管理体制提出了新的要求。

Resource suitability analysis in regional planning—with special reference to Wisconsin,USA

The demands and needs of our presently increasing population require that the social decisions for land use must be based on the best and most reliable information that the decision-makers can obtain. Growing mass of natural resource information should be presented in a concise and practical form which the planners and public administrators can readily use without a need to learn about natural resources in detail. One of the means to present this information is a resource evaluation system which consists of four levels of maps: basic resource maps, single-factor maps, limiting-factor maps and final land suitability maps. The basic process used in the system is developing a series of individual maps showing specific kinds of information and superimposing them to identify a degree of suitability for a specific land use. The authors provide an overview of the use of land suitability maps in land use planning in the United States; show what natural resource data planners can require and put to use; outline the way in which earth scientists can evaluate and present the data needed; and finally demonstrate the land suitability analysis by case studies. Also briefly discussed is the need for information other than earth-science data. Land use planning and decision-making process is an intricate mixture of scientific, engineering, ecological, sociological, economic, cultural and political factors and forces. Obvious as it may seem this fact is nevertheless often ignored in practice resulting in misunderstandings and mutual disbelief of parties involved.

Land use/cover change and driving force analyses in parts of northern Iran using RS and GIS techniques

To accomplish integrated watershed management and land use planning, it is necessary to study the dynamic spatial pattern of land use and cover change related to socioeconomical and physical parameters. In this study, land use and cover change detection was applied to the Lajimrood Drainage Basin in northern parts of Iran, an area characterized by rich and diversified agricultural and forest mosaic. The main of changes in the study area were forest–arable land transformation, which was only considered in this study. In order to detect these changes, at first, based on 1:25,000 digital topographic maps dated 1967 and 1994 and ETM⁺ satellite image dated 2002, land use map in these three dates were prepared. The results showed that the area with forest land use decreased about 3.2% in transition 1967–2002. Also, arable land increased about 36.9%. We suggested a method to analyze the driving forces and the spatial distribution of land use change. The maps of elevation, slope, and aspect were derived and classified by using digital elevation model (DEM). Also, the maps of distance from road, drainage network, and building area were selected as socioeconomical factors. These maps were overlaid and crossed with land use change map and land use change area ratio was computed. The results showed that the elevation, slope, and aspect were physical effective factors in land use changing. Also, by increasing the distance from building area and roads, deforestation rate was reduced.     

Mining geohazards susceptibility and risk mapping: The case of the Amyntaio open-pit coal mine,West Macedonia,Greece

During the last decades, numerous methodologies for the construction of both susceptibility and risk maps have been developed in order to identify and mitigate geohazards such as landslides and secondarily land subsidence phenomena caused by the collapse of natural or man-made underground cavities. According to literature review, the conducted research concerning the assessment of land subsidence risk due to the overexploitation of the aquifer is still at an early stage. This study focuses οn the land subsidence phenomenon due to the overexploitation of the aquifer occurring in the Amyntaio basin in West Macedonia, hosting the active Amyntaio open-pit coal mine. This phenomenon has caused significant damage to settlements, farmlands and infrastructure. In order to construct susceptibility and risk maps knowledge of the geological, geotechnical, hydrogeological and tectonic settings of the study area is required. The proposed methodology for the production of a susceptibility and a risk map of land subsidence was based on the semi-quantitative method Weighted Linear Combination (WLC). The results were evaluated with an extensive field survey action recording, besides the above-mentioned settings, the spatial distribution of surface ruptures. The excellent agreement between the produced maps and the findings of the field survey, proved the added value of the maps, assigning them as crucial tools for the management of land subsidence phenomena.

地面沉降对高速铁路的影响分析

北京平原区快速发展的地面沉降对高速铁路的发展构成了威胁,地面沉降与过量开采地下水造成的水位下降关系密切,为此有针对性地开展基于高速铁路的地下水动态与地面沉降相关关系研究对于高铁安全运行意义重大,特别是对于制定高铁沿线地下水开采方案、地面沉降减缓措施和工程措施至关重要。基于其对高速铁路的影响模式,本文将地面沉降分为区域沉降和局部沉降两种类型。针对区域沉降,利用Logistic方程,使用天竺、望京及王四营分层地面沉降和地下水位数据,构建了不同层位地下水水位变化与地面沉降之间的相关关系模型,通过ABAQUS计算局部地区,对于6m高路堤和15m CFG桩处理深度的地基而言,当渗透系数k=2m／d,距离线路边缘25m处浅层地下水下降10m将产生约61—85mm的沉降。     

Digital national land information

The digital land data maintained in the Geographic Survey Institute are listed in Tab 1. They are computerized for the digital national land information to establish a geographical data bank of land information.The digital national land information contains many kinds of land data, which have been maintained mainly as maps, aerial photos and statistics, and is stored as magnetic tape.The smallest geographical unit is either the standard mesh, geodetic coordinate or dots, according to accuracy of the original data.The digital national land information can be used in the various fields of geographical researches and in national or local land planning.In this paper, as an example of application, the housing land selection method is introduced, using the natural land data and the land use data.     

Mobility centre-oriented urban regeneration: examining place value of railway stations

Urban regeneration involves the notion of reconstruction of places, where regeneration initiatives are undertaken to ameliorate the quality of physical and social spaces, accrue economic profitability of space, and finally encourage environmental sustainability. Railway stations all around the world have a very important role to play in contemporary urban regeneration strategies as places of both social and material interest. With the progress of the twentieth century several issues like rapidly growing population, seemingly relentless urbanisation, an alarming rate of vehicle emission, and consequent pollution emphasised railway stations as critical places with great potentials of infrastructure development for the optimised functioning of urban centres. Thus the huge value of railway stations and their adjacent land has been acknowledged since the last quarter of the previous century. This paper aims to analyse the place value of railway stations and their immediate neighbourhoods within the urban fabric of a city using a relevant theoretical concept i.e. the ‘Node-Place Model’. Simultaneously it also draws attention to the notion of (re)development of functional spaces in and around the railway stations as a dimension of contemporary urban regeneration strategies, with the help of some global examples. This paper thereby reveals that in the urban centres throughout the entire world the railway stations are progressively attaining the focal position within integrated transport and land use planning strategies, either under the larger concept of 'Transit-Oriented Development' (TOD) or more simply, with the label of (re)development programme. This paper will significantly contribute to the ability of spatial policymakers to direct the future of urban growth towards public transit stations so as to achieve sustainable urban development.
