【摘要】 轨道交通沿线土地是线路运营主要的客源地,土地利用的结构和强度都要影响客源量和客源的稳定性。本文以轨道线沿线各段的土地利用结构和土地利用强度对客源量和客源稳定性的影响为准绳,分析线路各段的相对合理性。在土地利用结构的分析过程中主要利用景观指数和土地利用组合结构,从土地利用数量结构和空间结构来分析。土地利用强度的分析则选择人口密度,建筑密度和容积率作为指标。所有的数据的获取和分析都在ArcGIS和Fragstats3.3及Excel中实现。通过对各指标的分析,文章指出,东莞城市轻轨沿线土地利用类型丰富多样,空间结构较为合理,土地利用强度大,能够为轻轨线提供数量大,稳定性较高的客源,线路规划整体合理性高。在正线各段中,麻涌和道的合理性相对较低。从正线与比选线来看,虎门和大朗的比选线合理性不如正线,大岭山的比选线和正线的合理性相当。更多还原

【Abstract】 The land along railway route is an important source area of passengers.The land use structure and intensity along railway route will influence both the volume and stability of passengers.This paper analyses the rationality of city railway planning,taking the impact of land use to passenger volume and its stability as criterion.The study area is divided into 14 parts of zones which the railway passes through.GIS data is used to analyses the rationality of railway planning of the city. Two categories of indicators are used in the process of analysis.One is related to land use structure including landscape diversity index,dominance index and the contagion index;the other is used to describe the land use intensity including population density,structure density and floor area ratio.According to the urban land use classification system,the land use along Dongguan city railway route can be classified into 13 categories and 26 sub-categories,that is,residential land,commercial land,industrial land,land for storage,transportation,road and square,public green space,specially used land,agricultural land,water area,open space and hill land.The Fragstats 3.3 is used to analyze landscape indices. Based on the analysis,it is concluded that land use along the railway route is intent to a high diversity,and the structure and intensity of local land use suitable for the operation of transit.The land of the study area can steadily provide large amount of passengers for the city railway transport in the future and the planning of the Dongguan city railway route has a higher rationality.Some part of the railway transit,i.e.Guancheng,Nancheng,Houjie,Chang’an and Dongcheng are planned more rationally.As for Mayong and Daojiao,because of their low landscape diversity,population density,structure density and occupied by a large proportion of agricultural land and water area,the rationality of the planning is relatively lower.Some indices especially the land use intensity indices are favorable to the operation of the transit,but they are with uncertainty for building of the transit due to great amount of compensation to the residents and the land owners living in the buffer.So we should dialectically understand the value of the indices.更多还原
