Taking sections of the Dongfeng Canal, the Xionger River and the Wei River in New Zhengdong District for example, this paper applied water environment capacity to analyze the carrying capacity of surface water environment in the east development zone of the city. The analysis shows that carrying capacity of surface water environment in the study area is not good, carrying capacity of 3 studied waters for TP, BOD_5 and COD is approaching to the limit. New Zhengdong District, in terms of industrial structure, should promote the projects with less water consumption, less or no discharge of wastewater, and also should enhance the sewage treatment, improve recycling rate of the reclaimed water, and reduce the negative impact of sewage and pollutant discharge on environment.  相似文献

Along with the rapid globalization and urbanization,primitive ecological environment and cultural life atmosphere of urban streets and lanes have degraded,memories of the city have been lost,and cities have shown the tendency of convergence and homogenization.Taking the Confucius Temple Block for example,this paper applied cognitive map,oral interview and GIS spatial statistics to study residents' col ective memories of urban street and lane spaces,and found that the locals' collective memories of streets and lanes in the Confucius Temple Block declined gradually in the sequence of "aura area" → "secondary aura area" → "buffer area" → "blind spot area",and "civilian" urban design concept was claimed as the major incentive of the decline.Streets and lanes as important components of urban public spaces have specific historical connotations and genius loci,and they deserve wide concern from the academic circle and the society for their function of protecting collective memories of residents.  相似文献

Cities are currently confronted with many urban problems, such as water shortages, water quality pollution, floods, and the loss of habitats of aquatic organisms, and badly in need of a more comprehensive solution. In this context, the concept of "sponge city" is proposed. This paper, based on the theory of sponge city and low impact development, elaborated the origin, development, connotation, and construction method of "sponge city" concept. In this paper, the urban design scheme of Renbei District in Chengdu was taken for example to analyze the geographical environment and climate characteristics of Chengdu and explain the formation and verification of the scheme. It is considered that the "sponge city" is different from the traditional urban infrastructure. It is essentially an ecological approach. Its core is to build a cross-scale urban water ecological infrastructure to comprehensively solve the prominent water-related problems of urban and rural areas in China.  相似文献

Study on the relationship between landscape beauty and ecological beauty is an important scientifi c problem that refl ects the nature of man-land relation, and current academic researches on this topic are most based on a single perspective. Therefore, this paper took the Confucius Temple–Qinhuai River Scenic Area in Nanjing City as a typical case of urban traditional cultural tourism destination, adopted landscape pattern indexes and balanced incomplete block comparison and evaluation method as the evaluation standards of ecological beauty and landscape beauty, and analyzed the coupling characteristics and rules of landscape pattern and landscape aesthetics. The results showed that(a) The overall landscape of the study area had higher fragmentation degree, but different landscape groups were infl uenced by different human interventions, landscape patches showed moderate diversity and heterogeneity, patch area, spatial distribution and spatial aggregation degree showed structural differences.(b) The locals and visitors had aesthetic perception of the study area, but preferred the beautiful natural scenery of the Qinhuai River, as well as the historical buildings and cultural landscapes that contain rich memories of the city.(c) Landscape pattern and landscape aesthetics showed coupled complementation and harmonious coexistence. The Confucius Temple–Qinhuai River Scenic Area has profound historical and cultural background, but it has witnessed gradual loss of cultural characteristics and fast "delocalization" against the background of rapid urbanization. As an urban traditional cultural tourism destination, it carries the responsibility of protecting city memories and inheriting regional cultures.  相似文献

The analysis of the service range and optimized layout of urban parkland through scientific methods is conducive to urban ecological environment, urban fabric and stable order to provide accessible recreational places for residents. This paper took Jianghan District in Wuhan for example, based on the GIS network analysis and vector databases of road network, park and population, to obtain the irregular service range of different types of park and bearing capacity. The results showed that the service range of daily recreation within 20 min accounted for 75.5% of the total area, and the bearing capacity of Lingjiaohu Park, Wangjiadun Park, and Longwangmiao Park was low. It was thus concluded that there were visible blind areas and invisible blind areas in Jianghan District. Therefore, specific optimized layout of parkland was implemented in different blind areas to effectively combine park green space and residents' recreational activities, so as to achieve reasonable layout of urban parkland.  相似文献

Waterfront area is always a central district in a city, and favorable designs improve taste of the city. With the further urbanization and improvement of living standards, design of waterfront area has to meet not only needs of water conservancy and flood control, but also psychological needs of users. Using flexible design principles and methods, urban waterfront areas will be more flexible and capable of adapting to changes of neighboring environment.  相似文献

With the development of city, more and more people are aware of that like the traditional building, the historical block should be protected because of the historical deposits. However, for a long period, more time are spend on material conservation, such as the archaeological studies and restorations of historical vestiges and their surroundings, while little is spend on spiritual aspects, such as the research on folk custom, social environment and humane studies. From an international academic communication-the conception design of Ciqikou, it is suggested that the conservation of historical block is different from that of single building. In order to preserve the integral environment of historical block, the dwelling environment of local people should be taken into account. This paper aims at comparison of and discussion on the protection and development of historical block both at home and abroad.  相似文献

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt Three Bays, One Core Six Towns, Two Axes Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.  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
