论中国城市化进程中的土地合理利用

随着我国社会经济的快速发展,我国城市化的速度进入了高速发展的时期,但城市规模的蓬勃发展带来的却是土地资源的严重稀缺。因此,如何在城市化的过程中处理好土地资源的利用是当前我国政府必须重视的问题。本文首先介绍了我国城市化进程中土地资源的利用现状,之后阐述了土地资源合理利用的意义,最后提出了城市化进程中土地合理利用的基本策略,希望对我国城市化的发展有一定的指导和借鉴作用。     

关于城中村改造问题的思考

城中村是我国在快速推进城市化进程中出现的一种新的城市化问题。它可以简单地理解为"城市中的农村",是在城市市区范围内,仍保留农村生活习惯和农村管理方式,使用集体土地,以村民委员会为组织形式的行政村的居住村落。城中村问题是目前我国多数城市发展过程的瓶颈之一,是城市总体规划实施的难点。本文通过对城中村类型、产生原因、改造必要性等方面的分

Vulnerability and sustainable development mode of coal cities in Northeast China

In this study, by carrying on the spot investigation to the seven coal cities in Northeast China and interviewing with the local authority and the residents, the authors definite the vulnerability that is closed to exposure, sensitivity and resilience, and set up vulnerability model of coal cities in Northeast China. At the same time, the authors broadly illustrate how the components of natural-social-economic system act in the coal area, so as to probe the ways to reduce vulnerability more effectively, such as preferential national policy and so on. Furthermore, the article studies the relationship between vulnerability and sustainable development. Vulnerability is a spatio-temporal function of sustainable development. The regional sustainable development refrains the spiral ascending of vulnerability. And the regional vulnerability and sustainable development appear in turn. Then the article analyzes the natural vulnerability, social vulnerability and economic vulnerability of coal cities in Northeast China. At last, combing vulnerability model and situation of coal cities in Northeast China, the authors put forward regional technology innovation mode, multi-dimension structure transformation mode, attracting investment mode and recycling economy mode to reduce vulnerability.     

Sustainable development of the seriously polluted cities in China

The environmental problems in the seriously polluted cities in China have been paid attention to by policy-makers and foreign and domestic scholars. However, it is very difficult to improve the environmental quality fundamentally due to its complexity, for example the formation of the seriously deteriorated environment. It is considered that the terminal harnessing is an important way, but the spread of high-level terminal treatment is restricted by the limit of funds and technological level. Therefore, the way for a sustainable development of the seriously polluted cities should be multiple-sided, which is to correlate the operation of environmental protection with the operation of city construction. To achieve an identity of these opposites, measures should be taken during economic development and environmental protection in every developing stage. In this paper, the authors take Benxi City as a case study.     

RELATIVITY AND SUSTAINABLE DEVELOPMENT

From the realism of science, and taking the guide of EINSTEIN‘s Relativity as guide, this article called in question the present theory of the sustainable development by the rational thinking of philosophy and a close logic inference. It is found that there are many paradoxes to the theory. Through more deepening and meticulous inference, we arrived at philosophic language of science about the sustainable development. The sustainable development is “non-sustainable development”, and the non-sustainable development is “the best sustainable development”. While carrying out philosophical principle thinking and repeating science demonstration for the sustainable development, this article got further confirmation that the existence of human being at the minimum environment cost may help them obtain motive power of the sustainable development. In fact, this foundation motive power exists in the flow of development in different organization levels, meanwhile it exists in strategy of intuition living of the ancient people. Only in relative lower environment cost to live can we get the support system of science for the sustainable develooment, and be able really to achieve the basic goal of the sustainable development.

Urban regional structures transformation and sustainable development: Case study of Nanjing megalopolis

Since 1978, many changes have happened on the background of urban regional structure in China, such as the economy system restructuring, the social transforming including the population flow accelerating and social demand diversifying and individualizing, the political and economic systems reforms, the rise of the real estate market and the changing relationship between human and nature. From the macroscopic view, these changes make the national urban system to be a newer pattern with a widening gap among the cities in spite of the rising of the cities as a whole. At the same, the urban land use structures are changing with both the trends of intensification and diversification, and the trends of the regional diversification and the economic integration. Besides, urban structures with multiple centers are emerging in several metropolitan areas in China. These changes and trends mentioned above are confirmed by a case study of Nanjing City, a growing metropolitan area in east China. The case study also points out some problems in urban regional structure reforming, especially the poor social and ecological considerations. We should pay more attention to some ideas like balance of intensification and decentralization, development of suburban centers and a reasonable mixing of the functional activities to develop a sustainable urban regional structure. Biography: XU Yi-lun (1971–), male, a native of Zhejiang Province, Ph. D. His research interests include urban geography, urban and regional planning.
