Circular agriculture is an essential way to realize the positive recycling of ecology and harmonious development of the country construction. The sustainable development of Beijing's mountain areas depends on the background and orientation of ecological economy. Beijing's mountain areas bear the responsibility of protecting the ecological safety of the whole Beijing district and also the exploration of circular agriculture in mountain areas is very important to promote the sustainable use of agriculture resources. Beijing's mountain areas have possessed some practical experience in recycling agriculture development. Through summarizing the development mode and analyzing the development practice, the article puts forward three key segments of promoting Beijing circular agriculture development: strengthen propagate, develop superiority and built management mechanism.  相似文献

As the protected areas of land and coastal environment, nature reserves are designed to address how to reconcile the con- servation of biodiversity, the quest for economic and social de- velopment and the maintenance of cultural values. This paper establishes a framework for nature reserve development that seeks to incorporate ecotourism into its strategies. The overall purpose was to identify the information needs required for a comprehen- sive nature reserve that incorporates ecotourism related values. It also illustrates the utility of this framework in the context of the Wuzhishan Mountain Region of China. A literature review, the first phase of a visionary strategy and a subsequent gap analysis for available management information were undertaken in order to achieve this paper’s purpose. Finally, recommendations are pre- sented for integrating ecotourism into nature reserve development in the Wuzhishan Mountain Region  相似文献

China's circular economy is still at the initial stage, whose development has many difficulties and problems requiring immediate resolution theoretically and practically. Due to the differences of regions on the scale of land, endowment of resources, economic basis and cultural background, the developmental levels and capabilities of circular economy are inevitably different. Based on establishing the indicator system for assessing the developmental level of regional circular economy, spatial variation of China's circular economy is measured by the quantitative measurement using principal component analysis, and the existing problems are also analyzed and discussed. On one hand, the differences of the development capability of the circular economy of different provinces (cities) are profound in China; ①Difference between the first category (strong) and the second category (relatively strong) is 1.1264 points. Difference between the second category and the third category (relatively weak) is 0.3867 points. Difference between the third category and the fourth category (weak) is 1.0238 points. Difference between the first category and the fourth category reaches up to 2.0869 points. Average difference between the area where the developmental level of circular economy is relatively strong and the area where the developmental level of circular economy is relatively weak is 1.3617 points. ②The differences of the distribution of the areas, with different development capability of circular economy, which are located in the three economic regions of China, are also profound. The regions with a relatively strong development capability of circular economy are mainly located in the eastern economic area, which account for 22.58% of the whole regions, while only account for 12.90% in the middle and western economic areas. On the contrary, the regions with a relatively weak development capability of circular economy account for 48.39% in the middle and western area, while account for 16.13% in the eastern area. On the other hand, among regions with different development capability of circular economy, the regions with a relatively weak development capability of circular economy are in a dominant position, which accountfor 64.52% of all the provinces (cities), which indicates that the development of the China's circular economy still has a long way to go. Though certain achievements have been made in the development of China's circular economy, in general, there are still some obstacles to be tacked in the development of China's circular economy which require the economic, legal and administrative methods.  相似文献

Abstract

Makerspaces – open access design and fabrication workshops – provide new contexts for design practice through ‘distributed production’. The global community of makerspaces has evolved quickly and in turn, substantial hype is attributed to its potential for radical sustainable innovation. In this article, we explore this potential in the context of the new ‘circular economy’ agenda. We focus the research on the critical role of makerspace managers/founders who are recognised as gatekeepers to circular practices. The research method is action-led including expert interviews (academics and founders/managers) as well as two generative context-mapping workshops, run at selected makerspaces in collaboration with their founders/managers. We unearth everyday ‘how-to’ guidance to interweave circular practices within makerspaces from the outset by: fostering an enabling culture; building local connections; nurturing individual/community capacities; and stimulating practical know-how. However, while the research reveals immense opportunities to cultivate circular literacy from within makerspaces, the prospects to ask more profound questions about our economy, through makerspace practices, are found to be compromised by day-to-day concerns. The insights from this research can act as a starting point for future work in this emerging research area.  相似文献

The vulnerable eco-area is one of the important research targets in the field of sustainable development. It is the requirement of building a well-off society in an all-round way that we should study more on the vulnerable eco-areas, deal with the relationship between environmental protection and economic development, speed up the economic development in these areas and increase the living standard of the local people. This paper puts forward the countermeasures of environment---economy coordination, on the basis of the recognition of eco-environment features and social economic conditions in the vulnerable eco-areas of China, in view of the progress in sustainable development studies of the vulnerable ones, taking the transitional areas of farming and pasturing in northeast China as an example to study the regional environment vulnerability.  相似文献

The paper tries to explore circular economy from the viewpoint of the system theory. Circular economy is a kind of complicated economic activity, and it is a wholly new ecotype economy proposed by Western countries after they had summed up many experiences and lessons from traditional economy. It is an entirety and has many layers. It keeps an open and dynamic balance. Because the system theory is the theoretical foundation of circular economy, we should systemically analyze and study circular economy from the macroscopic view, correctly grasp its operational laws, improve its service functions, and realize human beings' sustainable development. The paper introduces the content and general characteristics of the system theory and the idea of circular economy. Then it analyzes circular economy based on the system theory. The paper concludes that the integration of circular economy and the system theory can promote the functions of circular economy.  相似文献

Feeding a growing population exceeding 1 billion is a big challenge to the Chinese government and has partly led to the self-sufficient policy in grain production and supply for decades. However, the efforts to push grain production everywhere have resulted in not only deterioration of the environment but also stagnation or even reduction in farmers' income as production costs continue to increase. This situation might be worsening after China's accession to the WTO that provides market access for bulk commodity imports. A sustainable development in Chinese agriculture depends on diversification, or structural adjustment, that allows Chinese farmers to fully utilize their comparative advantage in production of labor-intensive goods. Past experience has shown that diversification has contributed more than a half of the growth in Chinese agriculture during the reform period and reduced stresses on the environment at the same time. It is likely to contribute even more to Chinese agriculture in the future an  相似文献

This paper first constructed a system to evaluate the innovation efficiency of industrial companies within Mainland China. Then, a principal component analysis (PCA) was performed to these indicators for dimensionality reduction, so as to figure out the technology innovation efficiency in these two phases, respectively. Finally, the overall efficiency of industrial companies in different regions was estimated and factorized via data envelopment analysis (DEA). The results showed that: (1) the efficiency of green technology innovation of industrial companies in China was relatively low as a whole, which mainly resulted from pure technical efficiency (PTE). Further, this huge gap continues to expand in these regions. And both PTE and scale efficiency (SE) in central and western regions leave much to be expected. (2) In the first phase of green technology development, when environmental factors were concerned, the efficiency was much lower than that without environmental considerations. Besides, the central and western regions were facing increasingly severe environmental problems, and there was a wide disparity in technology development efficiency among eastern, central, and western regions. (3) In the second phase of green technology commercialization, there were still more rooms for improvement in raising the efficiency of green technology innovation, and the efficiency in eastern, central, and western regions was ranked from highest to lowest. (4) Liaoning, Hebei, Heilongjiang, Xinjiang, Shanxi, Inner Mongolia, Yunnan, and Qinghai should focus on improving their technology; Jilin, Jiangxi, Anhui, and Guangxi should make their efforts to reduce resource redundancy; whereas Ningxia and Gansu should try to solve the above two issues.  相似文献

agglomeration of the Yangtze Delta (UAYD), one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modern cities, and great achievements have been made in this regard. 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.  相似文献

Based on urban-rural contrast coefficient, this article designs the agriculture relative development index (ARDI) as indicators measuring the intensity of urban rural dual structure which is comparable among the countries of the world. This article calculates ARDI of 40 countries from 1980 to 2004. The result shows that ARDI in the developed countries and most of the middle-income countries are rising and yet there are declines in most of the low-income countries. The result also showed that most countries' ARDI will see a decline at the earlier stage of industrialization, so their dual economic structure will also aggravate and urban-rural gap will widen. With the economic development, the tendency will change and ARDI presents a U-shape change overall. The turning point is when a country becomes a middle-income one.  相似文献

On the basis of data collected from Liupanshan poverty-ridden areas, the paper selects 24 variables under 4 groups to figure out the influencing factors of subjective well-being (SWB) of peasants in ecological migration with the method of Ordered Probit Regression. As is shown in the results, variables under peasants’ personal endowment group and resource of the development group have little impact on peasants’ SWB. The variables with observable impact are concentrated in the living condition group and the public atmosphere group.  相似文献

In the first, the paper gave a retrospective analysis on the comprehensive assessment of circular economic development. According to the requirement of improving resource & environment efficiency, the paper designed an analytical framework for a comprehensive assessment of regional circular economic growth, which consists of the goal, object and technical line of the comprehensive assessment of regional circular economic development. Given that, the paper discussed the criterion for choosing the assessment index, the approaches of index's weighing determination, the means of data standardization, and the reference system of assessment index value and so on. According to the framework of regional circular economic development evaluation, the paper made a comprehensive evaluation of Jiangsu Province's circular economic development. The result shows that from temporal change, Jiangsu Province's circular economic development had different stages; from the spatial comparison, there is variance among different regions, which could be divided into different types according to the spatial variance and the relation between the development of circular economy and the aggregative index number. There was a remarkable correlation between circular economic development level and GDP or the 2nd industry GDP. Finally, the ?aper gives some suggestions on how to promote the development of drcular economy in Jiangsu Province.  相似文献

Abstract

Based on the Environmental Kuznets Curve theory, the authors choose provincial panel data of China in 1990–2007 and adopt panel unit root and co-integration testing method to study whether there is Environmental Kuznets Curve for China’s carbon emissions. The research results show that: carbon emissions per capita of the eastern region and the central region of China fit into Environmental Kuznets Curve, but that of the western region does not. On this basis, the authors carry out scenario analysis on the occurrence time of the inflection point of carbon emissions per capita of different regions, and describe a specific time path.  相似文献
