浅析城市人居环境的评价及优化措施--以苏州市为例   总被引:10,自引:2,他引:10  
在探讨人居环境的概念、分类的基础上,采用以某一年为基准的相对比较法,构建城市人居环境评价指标体系。并以苏州市区为例,对1995~2000年苏州市区人居环境进行了较为详细的分析与评价。分析结果表明,尽管1995年以来苏州市区人居环境质量有较大的改善,但改善速度仍落后于经济增长速度,并且生态环境和居住条件改善更为缓慢。针对这些问题,从城市规划、城市化发展战略、城市生态环境建设等方面,提出了优化苏州市人居环境的具体措施。  相似文献

Increasing Chinese urbanization and industrialization has prompted greater attention to the study of human settlement and the human-land relationship in the fields of geography, architecture, and urban planning. We used bibliometric methods and statistical software to review 180 articles on human settlement in 16 Chinese geographical journals. We found that Chinese geographical human settlement research is characterized by the following:(1) Most research focuses on human settlement extension, valuation indicators, models for urban and rural settlements, theoretical exploration and the planning practices of single-factor, human settlement and complex, geographical livability in macro-scale, urban settlement differentiation and ideal patterns in medium scale, the comprehensive evaluation of settlement environment, and the planning of community units in micro-scale, community settlements; socio-cultural investigation and warnings about advancing human settlement.(2) No progress has been made in synthesizing and integrating method systems. PSR models and DPSIR models are used for targeting mechanisms, while the standard settlement evaluation system was composed of physical economic indicators by questionnaire surveys. On the other hand, spatial clustering based on GIS has been a frequent focus in recent years. Pioneering research on human settlement and theoretical systems within the context of China's urbanization and industrialization will provide guidance on the sustainability of Chinese cities and regions. The following five aspects require greater attention:(1) Natural suitability research on human settlement, and a survey of human settlement demands to reflect the range of different demands concerning ecologically suitable settlements in urban environments, the corresponding valuation indicators, systems, and evolution, and the impact of the residents' socio-economic attributes.(2) Spatial-temporal evaluation and sustainability research on urban and rural human settlement at various scales, focusing on evolution and spatial differen-tiation at various scales such as city clusters and comparisons between cities, within the cities and communities.(3) Development of theory and technology for human settlement evolution research, including detection technology and methods, data mining measures, and forecasting and emulation of regional and urban human settlement evolution processes, mechanisms and patterns.(4) Research on the control of human settlement that focuses on optimization, patterns, and policies for effective management and development.(5) Estimating the human settlement system service value and establishing suitable human settlement systems, including social, economic, cultural and ecological service values.  相似文献

The coordinated development of human settlement environment and economy is of vital significance to urban sustainable development and urban ecosystem health. Urban human settlement and economic systems exist in urban ecosystems, which are a structural complexity. Therefore the research is being challenged by some uncertain factors between human settlements and economic systems. However most of the researches were focused on its determinate objective aspects and qualitative analyses while less concern on the quantitative evaluation of coordinated development of urban human settlement environment and economy, especially little on its uncertain aspect. At present, the urgent task is to study the coordinated development of urban settlement environment and economy in terms of the effect of uncertainty. This study analyzed the uncertain characteristics, which would be confronted at different stages, such as confirming the index categories, their bound values, and their construction rate, etc. According to the actual urban conditions, many construction principles based on uncertainties are put forward and an indicating system for human settlement and economic evaluation is established. Moreover, the application of fuzzy mathematics presents a new method and a calculation model for the comprehensive assessment of the coordinated development of urban human settlement environment and economy. The application of the method and model in Changsha city of China showed that the assessment results can reflect not only the overall coordination degree of the city, but also the mode of interactive mechanism between urban economic system and human settlement environment.  相似文献

"Based upon recently published data, this paper investigates urban settlement size trends in the former USSR and its republics during the intercensal periods of 1970-1979 and 1979-1989. Results indicate that although a trend toward largeness of the Soviet urban hierarchy continues, a slowing in this direction has occurred. Among republics, all had an increasing trend towards largeness on at least one and usually all three summary measures of urban settlement size structure. The RSFSR [Russia] and Armenia especially consistently evidenced a relatively high degree of largeness, while the former Baltic republics generally revealed a relative smallness."  相似文献

"The authors attack what they call 'superurbanism' and 'agglocentrism,' an excessive preoccupation among some Soviet geographers with urbanization and the formation of urban agglomerations. The authors advocate what is known in Soviet geography as a 'unified system of settlement,' meaning a harmonious blend of both urban and rural forms. The 'agglocentrists' are said to derive their ideas from Western models, and the authors [note the growing] disenchantment with excessive urbanism in the West."  相似文献

Abstract

The built-up area of Addis Ababa and its surrounding towns is expanding into the peri-urban region leading to high losses of farmland, directly influencing the food production for the urban population. This paper investigates the patterns of settlement growth in the region surrounding Addis Ababa and their impact on peri-urban agriculture using an urban spatial scenario design model. The effects of two population density scenarios are explored within the framework of a proposed master plan. The model output was used to estimate areas of different suitability levels that would be lost to the modelled settlement expansion. The settlement area in 2038 would represent 29% of the case study’s total area in the low-density scenario but only 19% in the high-density scenario. Compared to the low-density scenario, the high-density scenario would only require a third of the agricultural land transformed into settlement areas. Settlement development would contribute to higher losses of land suitable for cultivating important export products, high nutritional value and import-substituting products. The scenario approach can support sustainable regional planning for settlement expansion that conserves valuable farmland in the peri-urban area and contributes to building capacity for strategic planning of the city regions of sub-Saharan Africa.  相似文献

"Metropolitanisation has been observed by experts as one of the main characteristics of Indian urbanisation. Rural to urban migration has been a major player in urban growth of metropolitan cities, particularly Delhi. Not only Delhi but its hinterland [are] urbanising fast as compared to the hinterlands of other major cities of India. There are several processes of urbanization viz. historical, physical, demographic and economic. In this paper the role of demographic processes in urban expansion of Delhi [is examined]."  相似文献

"The author extends his earlier work on the concept of a support framework for settlement (i.e., interconnected linear and nodal elements supporting the activities and needs of population within the settlement system), developed initially for the Caucasus region, to the entire country. A five-level hierarchy of urban nodes, ranging from highly developed agglomerations to small and medium-sized cities, is proposed which is used to analyze the level of urban support provided in the major economic regions of the USSR."  相似文献

"A survey of current urban issues and trends in the Soviet Union sets the stage for an analysis of the problems of the urban system of the USSR and discussion of recent efforts at planning and policy development for a national settlement system. The General Scheme of Settlement, issued in 1975 and revised in 1982 to guide the development of such a national system, is examined as is the ensuing debate between two opposing schools of thought as to the best approach for restructuring the urban system."  相似文献
