It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the con- structiori of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.展开更多

Views of this paper is that social support and psychological capital enhancement have a significant impact on the new generation of migrant workers integrated into the city. Finally, propose strategies to facilitate this group more easily integrate into city life.展开更多

For urban core areas in China, in which the metro was built later, there was more consideration for meeting the traffic needs of cities. However, there are few studies of collaborative planning for metro stations and their surrounding space. Thus, there is an urgent need to conduct research on collaborative planning for metro stations and their surrounding commercial space in urban core areas. Unlike conventional methods of integrated design of stations and cities, this paper, based on the theory of place spirit, took Chunxi Road Metro Station in Chengdu and its surrounding commercial space for example. It explored the pattern and characteristics of the place in the commercial space around the metro station, analyzed the strategies of cultural and commercial integration, as well as architecture, street, landscape and other aspects of the design method in the space, and explored the strategies of place-making and infiltration, providing a reference point for the development and place-making of the commercial space around metro stations in urban core areas.展开更多

Mianzhu is an example that is officially named as one of the pilot cities for multi-plan integration on the county level. The paper firstly analyzes the problems associated with multi-plan integration in Mianzhu, including the indeterminate hierarchy of the planning system, the disunity of technical standards, problems regarding spatial order, coordination and division of powers and functions, and the intensive utilization of spatial resources, the lack of a coordination mechanism, and low participation of experts and the public. Secondly, by learning from Germany's spatial planning, and also practical experiences of pilot cities for multi-plan integration in China, this paper creatively brings in the connotation of multi-plan integration on the county level, and further proposes a power division based on three-level planning system and three kinds of space, the reinforcement of a spatial order, intensive spatial utilization, and a planning coordination mechanism, hoping to provide reference to other cities.展开更多
