Landscape Pattern Optimization of Chengdu Based on Modern Garden City

TOptimization of regional landscape pattern is significant for improving function and value of ecosystem,and restraining the expansion of urban layout.Taking Chengdu City for example,this paper applied RS and GIS techniques,landscape indexes and ecological service function evaluation to further analyze the temporal and spatial characteristics of landscape pattern and spatial differences of regional ecological functions,and on this basis,identified the spatial distribution of ecological source lands.Based on the long-term objective of building Chengdu into a modem garden city,this paper applied the accumulative cost distance model and introduced garden city theory to construct regional ecological corridors and ecological nodes,and explored the approaches of optimizing landscape pattern of modem garden city.The results showed that a great deal of arable land has been transferred to construction land in the urbanization;intensity of regional ecological functions showed obvious spatial differences;ecological source lands were mainly distributed in the Longmen Mountain,the Qionglai Mountain,the Changqiu Mountain and the Longquan Mountain;according to actual conditions of the study area,the road ecological corridors,river corridors and agricultural corridors in the layout of "four rings and six radial corridors" were constructed;ecological nodes dominated by intersection,wetland and forest park were formed.This research method and results are significant references for building Chengdu into a modem garden

Low-carbon scenario and technologies in modern city——Case study of Shenyang

From a multi-dimensional perspective of economic development,carbon dioxide and industrial pollutant emission and resource consumption in the case study of Shenyang,this paper analyzes the resource consumption and environmental impact in the process of urban economic development and low-carbon transition and evaluates the emission reduction potential and scenario of various technologies. The results show that city plays a key role in global low-carbon economic construction,and it is pointed out that emission reduction technology in urban scale can reduce total amount of carbon emission to substantial extent. From the aspect of future development,the input of technology and economic growth pattern should be strengthened so as to realize economic development as well as the total amount reduction of pollutant emission.

Zhangjiagang——A Modern Port City

Zhangjiagang, located on the lower reaches of the Yangtze River and an important military town in ancient times, was previously under the. jurisdiction of Shazhou County. It became Zhangjiagang City in 1986, named after Zhangjiagang, a natural port in the area. With fertile soil, a good climate and sufficient rainfall, Zhangjiagang is a production base for high yield grain and good quality cotton. In addition, it is renowned for its variety of river food, chicken, peaches, grapes, wine, water melons and tea.

Residents’ Satisfaction Assessment of Outdoor Residential Spaces;A Local Study in an Urban Compact Form in Sana’a, Yemen—Winter Period

This paper studies the thermal performance of outdoor residential spaces in the old part—historical part—of Sana’a city in the winter period and its impact on the residents’ satisfaction who occupied the buildings which overlook these spaces and use them on a pedestrian comfort basis. The analysis was carried out through the results of field measurements which study the temperature, relative humidity, and the air movement inside the selected outdoor spaces in the period of winter (2 months) data recorded through the devices used and compared with those obtained from the General Authority of Meteorology and Aviation—Meteorology Sector. Despite the passage of years, the author remained occupied with the opinion of the people whose homes overlook those outdoors spaces and what is their opinion of their performance. Therefore, an assessment was conducted in November 2020 to know the opinion of the people about the performance of these outdoor spaces and to compare the results of the field measurements with the results of the assessment. The measurements were conducted by using data-loggers that spread in some outdoor spaces in 7 spaces in old city of Sana’a and in its modern extension during the winter period which is the time of concern of this work. The measurements showed that the outdoor residential spaces in the old city of Sana’a are represented an advantage for winter climate over that of the modern city, so the focus in this paper was on that outdoors with the question of the users of the outdoor spaces in the old city only to clarify their satisfaction with it and whether it has succeeded as well from their point of view. Results presented in this paper are important to consider the relationship between the climatical performance of outdoor spaces and the comfort of the residents in the urban environment and give implications for urban planners and architects to improve the climate-based design methodology towards sustainable developments.

The“Flaneur”in Modernist Poetry

Traditionally,there is a complete rejection of the city within poetry.Nevertheless,as urbanization sped up,cities eventually became the center of culture.In modernistcity poems,the speaker takes up the role of“flaneur”and conveys the poet’s reflections on urban life and urban people.By analyzing the characteristics and development of this image in modernist poetry,we can gain a deeper understanding of modernist poetry and urban life.

Le Corbusier’s urbanism:An urban characterisation of his proposals for inner cities

Le Corbusier’s urbanism is routinely met with a backlash of criticism,which often overlooks the complexity of his work.There is a tendency to focus on the characteristics of his proposal for Paris in 1925 or on the ideas of CIAM’s Athens Charter.However,such affirmations ignore the conceptual and qualitative evolution of his urban proposals.In this sense,the research hypothesis is that Corbusian urban models go beyond the Plan Voisin,diffused by urban planning theories as the unique paradigm of his urban ideas.Through analysis and characterisation of the inner-city urban plans of Le Corbusier,this report seeks to demonstrate the existence of other models and compares them to those often showcased in the partial examination of Le Corbusier’s urbanism.The following parameters will be analysed:(1)population densities and areas for(2)buildings,(3)vehicles,and(4)pedestrians.The results of this research indicate the need to parameterise and analyse Le Corbusier’s cities beyond a single case to demonstrate the diversity and evolution of his urbanistic work.This process seeks to dissipate the common view that falsely extrapolates ideas of his urban planning,largely that of his first proposal,for Paris.

Planning Order with Nature: The Transnational Experiments of Park System in Chinese Cities During Early 20^(th) Century

Park system planning has been regarded as a systematic, effi cient and rational approach that uses nature to organize and guide the social and spatial development of cities. As an important tool for city planning development, it became an international phenomenon fostering international communications, in the meantime promoted individual expressions of nature, and became one of the crucial planning strategies to reshape China's modern cityscape. This paper investigates the diffusion and development of park system planning in Chinese cities during early 20^(th) century. It elucidates the theoretical origins and practical experiments, identifi es the selective and diversifi ed transfer of Western models, and further reveals the insights of transnational urbanism and national identity. The research intends to provide some reference for the planning of park and green space system in contemporary Chinese cities under the background of globalization.
