可持续发展的理论与宏观调控模式 总被引:8,自引:0,他引:8
从可持续发展观和可持续发展战略出发,分析了传统发展观和发展模式的特点及其主要弊端;进而根据有关国际性文件中的可持续发展概念,给出了中国人易于理解的描述及其基本内涵,强调了人与自然和谐、发展与资源环境相协调是可持续发展的核心,并结合实例阐明了协同学理论是可持续发展的基本理论依据;在分析发展与资源环境相协调的基础条件之后,重点论述了它们之间的协调机制,提出了可持续发展的宏观调控模式。 相似文献

With 20% of the world’s forests, Russia has global potential in bioeconomy development, biodiversity conservation and climate change mitigation. However, unsustainable forest management based on ‘wood mining’ reduces this potential. Based on document analysis, participant observations and interviews, this article shows how non-state actors—environmental NGOs and forest companies—address forest resource depletion and primary forest loss in Russia. We analyse two key interrelated forest discourses driven by non-state actors in Russia: (1) intensive forest management in secondary forests as a pathway towards sustained yield and primary forest conservation; (2) intact forest landscapes as a priority in primary forest conservation. We illustrate how these discourses have been integrated into policy debates, institutions and practices and discuss their relation to relevant global discourses. The article concludes that despite successful cases in conserving intact forest landscapes, there is still a frontier between sustainable forest management discourses and forestry practice in Russia.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01643-6. 相似文献

This article critically reviews the evolution of urban environmental management in Shanghai since 1978. Established in a transitional
postsocialist economy and shaped by a spectacular urban redevelopment process, the current environmental management framework
of Shanghai has succeeded in mitigating major industrial pollution and improving urban amenities with unprecedented pace and
magnitude. However, it generally failed to take social equity and environmental justice issues into consideration. Based on
Haughton’s models of sustainable urban development, this article proposes four priorities and five principles within the framework
of a fair shares cities model for the future environmental management of Shanghai and briefly discusses their policy implications
and implementation issues. The authors argue that Haughton’s approach is relevant to Shanghai’s case because the essence of
his argument—the multidimensional equity principles—is the core of the concept of sustainable development. 相似文献

The issue of sustainability in the construction industry is very prominent, as the industry often causes adverse impacts on the environment through its use of large amounts of natural resources and by clearing large areas of their natural habitats. After the 1992 Earth Summit in Rio de Janeiro proposed the use of eco-labels to attain sustainable development, the growth and use of eco-labelling schemes have increased significantly. This study focuses on eco-labelling schemes, particularly the Singapore Green Labelling Scheme (SGLS) and the Singapore Green Building Product Certification Scheme (SGBPCS), and their contributions to the Singapore construction industry. The effectiveness of the schemes and of their drivers is determined through the analysis of survey results from two groups of samples (suppliers and architects) and interviews with some of the key stakeholders involved. It can be observed that the both the supplier and architect groups have some knowledge and awareness of eco-labelling schemes in the Singapore context. However, in terms of implementation, both schemes are only moderately effective in advocating the use and production of eco-labelled building products. It was also found that, out of several factors, “environmental rating” appears to be the only one that significantly influences the decision to use eco-labelled schemes. Furthermore, the results show that SGBPCS was not as heavily promoted in the architect group as in the supplier group. The architects perceived the SGBC advertisements to be less convincing than did the suppliers, and therefore they considered the SGBC's measures to promote the use of eco-labelled materials to be less effective. From the empirical results, strategies and measures are proposed for industry stakeholders to enhance the effectiveness of the eco-labelling schemes in the construction industry. 相似文献

One of the most challenging issues in the field of sustainable design is that of limiting the environmental impact of structural systems, as they contribute significantly to raw material consumption, global carbon emissions and solid waste production. This paper addresses the approach of the reuse of steel structure without melting which allows for savings in steel mass and the reduction of waste amounts offering moreover an opportunity to avoid environmental burdens related to the recycling process. Recent studies have stressed the technical feasibility of this strategy, which appears particularly effective in those countries in which a building's life is rather short, such as in Japan and US, though its application encounters more difficulties in most European countries, owing to longer building use. Besides stressing the architectural and structural feasibility of the above-mentioned strategy, this research work aims to quantify the mass savings that are achievable in this manner by presenting a real case study set in Italy. It consists in a railway station, which has been designed keeping in mind the partial employment of structural elements recovered from an old industrial building that is no longer in use. To estimate the amount of steel saved, two different structural models for the designed building have been carried out and compared. In the first one, the structure has been designed on the assumption of the reusing of recovered structural elements; in the second one, the same structure has been designed considering the use of new elements only. The final result of the analysis shows that steel reuse allowed for savings of up to 30% of steel. 相似文献
