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.展开更多

Its philosophy has a long history and development process in urban planning. The concept of jobs-housing balance generally refers to that the number of employed people is roughly equal to the number of occupants within a certain range. This kind of balance is conducive to reducing the commuting time and the change of transportation mode on the way that the employed people spend at work. The realization of jobs-housing balance not only helps to optimize the structure between residence and employment in the region but also is conducive to improving the work enthusiasm and work efficiency of the employed in the region and reducing the commuting costs of workers in the region. In addition, the relegalization of jobs-housing balance also has a certain impact and effect on alleviating the traffic congestion and improving the environment of the region. In summary, the realization of jobs-housing balance has a multi-faceted impact on the development of a city, and promoting the balance between occupation and housing is conducive to promoting the development of the city. The realization of jobshousing balance involves many areas. In this article, In this article, the development history of jobshousing balance is sorted out from perspectives of real estate development and management and urban planning, and its development enlightenment is discussed.展开更多

Guiding the healthy and ordered development of urban spaces was the key part and important approach to realize ecological cities. The guiding thought for development construction of ecological cities had been discussed, which was conducting laddered development according to the location and coverage of urban ecologically sensitive areas and protection grades of these sensitive areas. Then, it had proposed four kinds of protection and construction modes, which were tourism leisure green lands, relevant expositions, industrial areas and new city groups, and which had been analyzed by combining with successful cases, so as to provide feasible win-win development strategies of ecology and economy for the planning of urban ecologically sensitive areas in the future.展开更多

The system mainly involves three spatial scales: the urban scale, urban sub-domain scale, and single to few buildings scale. In it, different underlying surface types are employed, the building drag factor is used to replace its roughness in the influence on the urban wind field, the effects of building distribution, azimuth and screening of shortwave radiation are added, and the influence of anthropogenic heating is also taken into account. All the numerical tests indicate that the simulated results are reasonably in agreement with the observational data, so the system can be used to simulate the urban meteorological environment. Making use of it, the characteristics of the meteorological environment from the urban to urban sub-domain scales, even the among-buildings scale, can be recognized. As long as the urban planning scheme is given, the corresponding simulated results can be obtained so as to meet the need of optimizing urban planning.展开更多

In the general post-mining context of China and Germany, this paper suggests and outlines an approach that combines green infrastructure with specific concepts of post-mining landscapes. While Germany has a long tradition of post-mining restoration, concepts of green infrastructure are still poorly developed. China, on the other hand, has taken its first steps in the restoration of coal regions, and could profit from the new concepts while drawing on Germany's experience. The potentials of relevant strategies are investigated here through two case studies from Germany and China. Although there are significant differences in the post-mining development strategies of these two countries, it is clear that the green infrastructure concept can contribute significantly to a growth in ecosystem services. Four advantages of the green infrastructure concept are seen: First, it enables a systematic and highly objective assessment of mining impacts on the ecosystem. Second, the concept assists in the implementation of urban sustainability goals. Third, it is rooted in the local characteristics of landscapes. And finally, the green infrastructure concept seems to be highly compatible with tools of landscape and regional planning.展开更多

With Harbin and its urban planning from 1898 to 1917 as the subject of study from the perspective of planning historiography, this paper probes into the driving force behind Harbin's early modern urban development, historical phasing and characteristics of its urban planning, as well as evolution of planning and construction activities during this period. The findings reveal that Harbin's urban planning and construction activities were closely linked to Russia's political and economic interests and also reflected the political game between the powers led by Japan and Russia in the Manchurian region.展开更多

By sorting out the management and control indicators and methods of urban planning management departments for residential land and comparing the actual practices and internal design principles of the mainstream developers in land development and construction based on this method, it is believed that the phenomenon of landscape space fragmentation from the city itself in the residential quarter in the city is caused by the mismatch between the design strategy of the developer and the overall demand of the urban space. Lack of government departments’ planning for the integration of urban public resources is the inducement. In view of these problems, several solutions were put forward.展开更多
