Application of Aesthetic Value of the World Modern Garden City and Exploration & Design of Its Artistic Conception——Using Chengdu City as a Case Study

This study explored the origin and development of modern garden city,by integrating concepts of world modern garden city and characteristics of Chengdu cultures,analyzed the application of its aesthetic value and the design of its artistic conception.It was found that Chengdu City had high aesthetic value such as a large area of green spaces and unique recreational cultures,as well as a great potential of unifying idyllic images and natural cultures.To design Chengdu into a world modern garden city,the planning of its urban green space system should be taken as the foundation,"one group and three districts" as the construction system,urban folk cultures,logistics and traffic,information and other such networks as the support to achieve the "beauty of nature,social equity and urban-rural integration".

Changing Concepts of City and Urban Planning Practices in Guangzhou(1949–2010): An Approach to Sustainable Urban Development

By focusing on Guangzhou, this paper examines how different concepts of city in terms of urban-rural relationships are shaped in transforming China since 1949, and explores how they influence the way in which urban planning are practiced. In the pre-reform era, the city was defined as a productive space under the system of urban-rural segregation established for securing rapid industrialization. Urban planning was thus only concerned with the development of urban areas. In the 1980 s and 1990 s after the reform, institutional change and economic transformation mobilized the urban-rural linkages. The development of suburban areas was then considered by urban planning, but this consideration was a passive response to urban problems such as population explosion and water resources protection. Since the new millennium, the agenda for sustainable development and problems of uneven urban-rural development have called for the development of urban-rural integration. In this context, the city is conceptualized as a complex of mountain, city, river, farmland and sea, reconstructing the ideology of urban-rural division in defining urban development. Urban planning has therefore sought in an active way to develop a sustainable city embracing rural and natural elements, and to balance economic growth and environmental protection. It is argued that developing the concept of city as a complex of urban and rural elements contributes to the urban planning for sustainable urban development, while this conceptualization relies on the recognition of the integrated urban-rural relationship.

Study on Urban Forest Construction Concepts and Layouts in Taizhou City

Taizhou is an economically-developed port city on the golden coastline of China, characterized by typical coastal and combined green cores, mountains and waters, and special plants. This paper analyzed natural conditions and city features of Taizhou, assessed current construction of local urban forests, and proposed pertinent construction concepts in view of diversifi ed needs of urban development on forest construction. On the basis of the city development, principles of urban forest layout were put forward, and the overall structure of "one core, one belt, two rings, three corridors, four groups, fi ve windows, and multiple bases" was given for the construction of urban forest in coastal landscape cities, in addition, the effect and feasibility of the layout were analyzed.

Plant Diversity in City Parks under the Concept of Landscaping:A Case Study of Hefei City

Driven by the concept of landscaping,this paper analyzed the impact of plant diversity on landscaping function,arrangement methods and community structure by taking plot sampling method as the experimental axis and 3 urban parks in Hefei as the blueprint.Six plots with the size of 20 m×20 m were selected for investigation.There were 56 species of plants belonging to 50 genera and 42 families in the plots of Zhongshan Road City Park,48 species of plants belonging to 44 genera and 40 families in the plots of Four Seasons Flower Sea City Park,and 69 species of plants belonging to 57 genera and 45 families in the plots of Xiaoyaojin Park.The survey results show that there are following problems in city parks:lack of plant effectiveness,too homogeneous plant community,disharmony between landscape and environment,poor plant maintenance and lack of attention to ecological maintenance.Based on this,the optimization measures are put forward:increasing evergreen plants to avoid no scenery in autumn,developing plants with excellent landscape effects and a variety of colorful plants,paying attention to the shaping of spatial structure and landscape pattern,regularly taking care of plants and their surrounding environment.It is expected to provide some reference for the construction and development of Hefei city parks,ensure the healthy and stable development of city parks,and provide ideas and methods for the improvement of plant landscaping in city parks.

日本岸田内阁的数字化转型评析

日本虽较早关注数字经济发展,但其数字经济竞争力却落后于世界平均水平。为了破解日本数字经济发展滞后的困局,提升日本数字经济竞争力,应对日趋激烈的国际竞争,岸田内阁推出了涵盖数字田园都市国家构想、DFFT框架以及Web3.0、生成式人工智能技术等在内的一系列数字化转型政策。这些政策在日本数字化转型推进的广度、深度,以及执行力等方面展现出一定的亮点,但依然存在着企业与国民对数字化转型回应度不高、行政数字化改革阻力重重、数字人才短缺、地域间数字化发展程度差距较大、数字国际战略实施难度大、财政支撑空间有限、日元持续贬值等诸多难题,这使得日本数字化转型全面实现的可能性不高。尽管如此,岸田内阁数字化转型的推进也将对日本的经济、政治以及中日经济合作产生积极影响。

论中国古代都城规划的形制束与规范变迁——基于《考工记》后17个古代都城的实证

针对中国古代都城规划在学界一直存有争论的两个基本问题:(1)为什么《考工记》在后世实践中鲜有完全匹配其形制的案例?(2)为什么本出同源的明清都城与秦汉都城在空间形制上差异如此之大?从社会思潮的视角,提出自然形制、人文形制、功能形制以形制束的方式平行作用于都城,且其规范经多次历史变迁的总论点。剖析了各形制内容,阐述了规范变迁的社会动因与演变过程。实证以西周至清代17个都城城址为依据,通过对历代城址图的连续性切片解构,构建出以“形制-规范”为横轴、历代都城时序为纵轴的形制束解析框架和规范变迁表,并辅以“史料-图解-数据”的文-图-数实证支撑体系,验证上述论点。为古代都城规划摆脱孤立个案研究提供了一种新思路。
