In order to know how and why the land values changed inside the city,the land-value patterns of Beijing during the period from 1998 to 2005 were studied based on Kriging and GIS Method.The land-value data of Beijing had a second order trend,so the Ordinary Kriging(OK) method was used after removing the trend surface.The results showed that there was a positive relationship between land-value and ring roads.The patterns of land values were clearly affected by the eradiating function of the city centre,and there was no independent sub-centre formed.In addition to the impact of city center,the main reasons for the land value increase were the influence of city planning,the expected appreciation,and improvement of infrastructure and transportation.In the process of suburbanization of Beijing,the land values showed a significant growth pattern from the near suburban to the city centre,which caused by the restraint of land resources.  相似文献

ABSTRACT Cities and metropolitan regions face several challenges including urban sprawl, auto dependence and congestion, and related environmental and human health effects. Examining the spatial characteristics of daily household activity‐travel behavior holds important implications for understanding and addressing urban transportation issues. Research of this sort can inform development of urban land use policy that encourages the use of local opportunities, potentially leading to reduced motorized travel. This article examines the potential household activity‐travel response to a planned metropolitan polycentric hierarchy of activity centers. Behavioral observations have been drawn from an activity‐travel survey conducted in the Portland, Oregon, metropolitan area during the mid‐1990s. Evidence presented from exploratory analysis indicates an urban/suburban differential, with less daily travel and smaller activity spaces for urban households. Investigation of the travel reduction potential of the proposed land‐use strategy suggests that location effects could be offset by adjustments to household sociodemographic and mobility characteristics.  相似文献

According to the study on 39 sites of rail transit Line 3 in Chongqing, the sites are classifi ed into three types: residential type, business center type, traffi c hub type in this paper. The study shows that the sites have many problems such as discordance of land use, severity of spatial segregation, low rate of site utilization. To solve these problems, development approaches of site space resources within 1,000 m around the site area are further explored. The approaches include four aspects: characteristics of land use, functional composite, walking guide and shuttle transportation. In addition, appropriate planning and design methods are proposed.  相似文献

This paper examines the choice of residential location in the city of Chicago versus its suburban areas. Data from the 5 percent Public Use Microdata Sample from the 1990 and 2000 Census of Population and Housing are used. Particular attention is given to the effects of educational attainment. Place of work continues to dominate the residential location decision. However, conditioning on place of work, demographics, and income, educational attainment is found to be statistically significant in residential choice of the city versus the suburbs in 2000 for non‐Hispanic whites, especially those with graduate degrees. In contrast, more educated African‐Americans and Hispanics tend to locate in suburban areas.  相似文献

为了探讨城郊区不同土地利用方式对土壤养分及酶活性的影响,采用野外采样及试验室分析方法,对重庆市城郊区4种土地利用方式下的土壤养分含量及酶活性进行研究。结果表明:不同土地利用方式下土壤养分及酶活性存在较大差异。对于土壤养分含量而言,0~60 cm土层有机质和碱解氮均以水田最高;速效磷0~40 cm以旱地最高,表现为:旱地>菜地>水田>果园,40~60 cm表现为:旱地>水田>菜地>果园;速效钾0~20 cm以果园最高,其次是水田,再次是旱地,最后是菜地。土壤脲酶活性在0~20 cm具体表现为:旱地>菜地>水田>果园;过氧化氢酶活性在0~20 cm具体表现为:水田>果园=菜地>旱地。不同土地利用方式的土壤速效养分在各层基本达到显著水平,土壤酶活性差异显著性不明显(P<0.05)。  相似文献

This paper shares the findings of an active transportation (AT) study conducted in the context of a city in a developing country. First, a list of AT indicators was developed based on the literature review and expert opinion survey. Second, a face-to-face survey was conducted to collect information on individuals' socio-demographic characteristics, travel behavior, AT mode choice, and their perceptions regarding the AT conditions in their neighborhoods. Analysis of the survey results suggests that several socio-demographic characteristics are associated with AT use. For example, young adults and individuals with low income are the primary users of AT. Also, results suggest that students are mainly active commuters. The ratio of AT use increases with the number of bicycles in the household. Individuals tend to walk more when travel duration is less than 10 minutes. Educational areas are perceived as safer and convenient areas for using active modes of transport compared to other land-use types. Also, a higher proportion of active commuters perceive local roads to be safer from vehicular traffic compared to main roads. Many sectors such as planning, transportation, health, and education as well as non-government organizations will be benefited from this study.  相似文献

Under the background of supply side structural reform of the land market, this paper constructs a location choice behavior model of reduction from the perspective of rent maximization, explores how these factors affect the industrial land reduction location choice. We consider 100 industrial parcels in the suburbs of Shanghai as an example to analyze. It is found that the enterprises in development zones have greater advantages in economies of scale, labor productivity, pollution treatment, and tax payments than enterprises outside the development zone, so the low-efficiency enterprises outside the development zones are the preferred objects of reduction. The suburban areas have a stronger attraction than the outer suburbs in the process of location choice, and the closer the city center is, the more obvious the location advantages of enterprises in development zones. Under the control of the total amount of construction land, the land use structure should be constantly adjusted, inefficient enterprises outside the development zone should be preferred to the reduction object, and the government should actively guide enterprises to enter the development zones.  相似文献

目前快速城市化地区土地利用变化研究是土地研究的热点之一。为了研究快速城市化地区土地利用变化及其驱动因子,将快速城市化地区划分为城区、郊区和工业主导区3个部分,分2个时段研究了2002-2010年各分区土地利用的时空变化,并分析了土地利用变化驱动因子。研究结果表明,土地利用变化的热点集中在城区和工业主导区;2006-2010年研究区土地利用变化幅度要明显大于2002-2006年,其中两期建设用地分别增加806.40 hm2、3112.91 hm2;耕地、林地等地类大规模减少,二者两期减少之和均占减少总面积的85%以上,建设用地迅速增加;经济发展、外部政策干扰是刺激土地利用变化的主要因素。在土地利用和产业规划过程中进行用地分析,科学实施规划改善土地利用结构,保护水体、林地、耕地等地类,提高土地利用率是保护耕地、林地等地类的关键因素。  相似文献

农户对耕地投入的偏好,关系到耕地可持续利用与粮食安全。采用参与式农村评估方法,对云南省5对典型的近、远郊村512农户进行随机问卷调查,定量对比分析近、远郊村农户对耕地投入的偏好差异。结果表明:无论是劳动、机械、资金还是总投入,近郊村户均投入明显低于远郊村而地均投入则高于远郊村,近郊村耕地利用集约度比远郊村高;在耕地投入结构中,近、远郊村劳动投入均占绝大部分,但近郊村农户对劳动投入偏好强于远郊村而对资金投入偏好则弱于远郊村;对于耕地进一步投入意愿,大部分农户基本保持不变,但农户总体倾向于减少劳动力投入而增加资金投入,且远郊村比近郊村更为突出;农户总体趋向增加“好”质量耕地投入而减少“差”质量耕地投入,且远郊村比近郊村更为突出。应尽快采取措施促使农村特别是远郊村耕地顺利流转而扩大耕地流转规模,尽早实现耕地的规模经营与可持续性投入。  相似文献

While suburban areas have been typically related with urban sprawl, low density, cheap land price and low‐end manufacturing industries, relatively little attention has been paid to the spatial organization of innovation in suburban areas. In some Chinese cities, development zones (kai fa qu) in their suburban areas which are generally regarded as major spaces for traditional manufacturing industries have been transforming into spaces for innovation. This paper provides a case study of Nanjing, the capital of Jiangsu province in Eastern China by investigating and explaining the learning and innovation processes in suburban development zones. Drawing upon a unique database on 733 state‐certified high‐tech firms in Nanjing from 2008 to 2012 which contains detailed information on their addresses and number of patents, we observe strong spatial disparity in the distribution of innovation. Suburban districts of Nanjing where its three national‐level development zones and many provincial‐level development zones are located have become major spaces for innovation of the city. The planning of industrial clusters in development zones, the place‐based investment in the suburbs, and the suburbanization of universities are three major mechanisms behind the learning and innovation processes in Nanjing’s suburban development zones.  相似文献
