City squares are an important part of urban public spaces and play an important role in improving the quality of urban landscapes. For mountain cities, city squares with mountainous characteristics formed by its special geographical environment, which have more identifiability and uniqueness than that in plain cities, have greater influence on the promotion of city image. Their unique regional cultural characteristics and local customs and practices have shaped the totally different temperament of mountain cities. Based on the dialectical relationship between the square, the landscape and the culture, this paper took Shiyan Broadcasting Media Center Square for example to explore the ideas of landscape design in mountain cities. 相似文献

To develop the public traffic and setup a city form coordinated with the development of the public traffic has become a common sense in the full achievement of the city sustainable development. Due to the particularity of the exploration procedure and some difficulties in urban development, the policy on developing public traffic has not been realized in our country. Now it is on edge to solve these problems, particularly in the new area of development. In this article, the authors intend to find a practical way of establishing a ciity development mode with adapting the public traffic development by contrasting Lujiazui new area in Shanghai and the new east area in Chongqing. 相似文献

The space of mountain center city has diversified characteristics, which has interactive relations with the city overall function. Based on analyzing the contradictions between the characteristics of central city and the form of mountainous city, following the mountainous central cities' characteristics of multi-group, multi-center, multi-dimensional and multi-level, the theoretical model which reflects mathematic and abstract relationship between the characteristics and the overall function of the mountainous central cities was constructed. On the basis of the mountainous cities' characteristics and the scientific planning, the model develops the mountainous cities space and macro-functions theory. 相似文献

长沙市土地利用生态风险及评价 总被引：2，自引：0，他引：2
摘要：城市生态环境问题已成为制约城市可持续发展的重要问题,土地利用变化是城市生态环境改变的重要因素。长沙市作为中部经济发达、人口众多的大城市,其工业化和城市化的发展速度很快。强烈的土地需求对土地利用的强度、方式、规模、布局等造成了深远的影响,同时也对城市生态环境造成强烈的冲击,生态安全受到严重威胁。本文引入城市土地利用生态风险评价的概念,分析长沙市土地利用现状,阐述城市土地利用生态风险产生的原因,识别与土地利用相关的生态环境问题,综合运用主成分分析,K均值聚类等方法,建立了土地利用生态风险评价模型,分析和评价长沙市土地利用生态风险。结果发现该区所研究时段土地利用生态风险总体上变大,土地利用生态风险值从1996年的-0.85286（Ⅴ）,变为2006年的1.321039（Ⅰ）,期间变化波动明显,风险值在1996-1999年和2003-2006年趋于上升,2000-2002年趋于下降。根据此评价结论提出一系列规避和应对生态风险,协调城市土地利用与生态环境的对策。 相似文献

Buildings and spatial environment left by history record evolution traces of cities and significant events related to the cities, and as a particular carrier of culture, they are witnesses of city development, and show the later generations memories of the city history. In urban planning, historical images must be respected, the relation between ancient cultural relics and urban planning handled properly, city brand established, and city image improved. The author, on the basis of exploring signifi cance of urban ancient cultural relics, used practical cases to fi gure out approaches of preserving urban ancient cultural relics in urban planning. 相似文献

以重庆主城区为研究对象,利用Landsat 8传感器OLI和TIRS获取的遥感影像为数据源,进行城市聚落特征包括地形特征、土地利用等与地表温度的差异性分析。结果表明：城市的热环境空间分布差异较大,海拔高度对温度的影响强于地形起伏度;（NDVI、NDBI、MNDWI等）和地表温度的相关关系呈分段线性关系;不同土地利用类型的热强度和热变异程度差异明显,建设用地的温度最高且斑块温度间的变异性最强,虽然水体的平均温度最低,但斑块温度间的变异性却较高;从格网分析的结果可以看出,格网内部水体的“冷岛效应”明显、建设用地的“热岛效应”显著,耕地与自然植被面积的增加使得各空间格网温度更趋向于稳定。 相似文献

The policy of public participation in urban planning was first practiced in Europe in the 1960s. After 40 years of development, the policy has become the essential step of city planning in Western countries where as is just at the elementary step in China. For the purpose of knowing the situation about the policy performing in local cities and discussing the feasibility of public participation in urban planning, several kinds of investigation have been done. From the investigation, it is found that although the public participation has already been the important step of urban planning in some city during just several years,there are still many problems. This paper shows a panorama view of this issue. Th describe the future of public participation in e authors will offer some solutions according to the problems and the urban planning. 相似文献

China is currently facing the problem of large-scale destruction of the overall cityscape brought about by the rapid development of the city. The optimization of urban stocks and the improvement of urban quality have become the necessary paths for major cities to improve their urban soft power and obtain secondary economic growth. At present, most cities in China are still in the exploratory period of the protection of the cityscape, facing the dilemma of various ways but poor effects. Since the 1990 s, Yangzhou has begun to protect and inherit the cityscape, accumulating systematic protection methods and retaining the complete cityscape. This paper analyzed the characteristic cityscape of the ancient city of Yangzhou, sorted out its strategic methods in the planning management, and summarized the local experience in the inheritance of the characteristic cityscape, in order to provide a reference for China's future cityscape protection work. 相似文献

Districts of Chongqing is selected as the study area, which has a rapid rate of urbanization and eco-environmental pressure. The fundamental data of this study is the remote images and urban planning images of Chongqing city in 1988, 1993, 2000 and 2007. After data processing by RS and GIS, model calibration is applied to obtain the best parameters for the SLEUTH model. Then, the SLEUTH model is used for the simulation of the urban growth over the past 20 years. On the basis, the SLEUTH model is applied to predict the situation of urban expansion of the region in the next 10 years. The simulation results show that the calibrated model has a higher simulated precision for the urban expansion of study area, and the pace of urbanization has become relatively rapid in the study area, which may be closely related to the current land planning, road construction, industrial structure and economic policy. 相似文献

According to the investigations of urban barrier free facilities, there have been lots of progresses in constructions of barrier free in cities recently. But there are no systematic barrier free facilities in these cities, which would restrict the function and effect of urban barrier free facilities for the handicapped and the elder. This paper puts forward that there should be a development from the urban barrier free facilities to the urban barrier free environment. There are two parts in the barrier free environment,that is the hardy environment and soft environment. Finally,an in-series connection two-core model of barrier free environment has been designed and discussed. 相似文献
