三峡工程对长江流域可持续发展的影响 总被引:12,自引:4,他引:8
陈永柏 《长江流域资源与环境》2004,13(2):109-113
可持续发展观念应该正确理解,研究可持续发展不能脱离国家或地区的发展水平。在分析长江流域可持续发展的限制因子(频繁的洪水灾害、偏低的防洪能力、落后的社会经济水平及脆弱的生态环境)的基础上,从三峡工程的防洪作用、发电效益、航运效益以及三峡工程效益发挥的可持续性方面,研究了三峡工程对长江流域可持续发展的促进作用。同时论述了三峡工程的建设对长江中上游地区生态环境综合治理及库区社会经济发展的带动作用。认为三峡工程的建设符合我国当今可持续发展战略,是全面促进长江流域社会经济环境可持续发展的关键性工程。 相似文献

江苏沿江开发研究 总被引:10,自引:2,他引:8
随着中国加入WTO和经济全球化进程的加快,长江三角洲以其独特的滨江临海的区位和发达的制造业基础,正在成为新的投资热点地区。江苏省沿江地区是长江三角洲重要的组成部分,拥有800多km的长江岸线和8个经济发达、人才资源优势明显的经济中心城市。传统的制造业基础和相对低廉的加工成本、商务成本,使江苏沿江开发既有对外来资本的吸引力,又有自我发展的内生机制。重点研究了全球化背景下江苏沿江开发的战略问题,主要包括:①江苏沿江地区开发的环境和条件比较分析;②沿江产业带重组与实施跨江开发;③再造新战略据点;④打破行政区界限沿江联动实施区域一体化,等等。最后指出:加快江苏沿江开发,必须科学规划、统筹安排,做到空间合理、时间有序,同时考虑沿江的环境容量有限,应实施可持续发展和南北联动的开发战略,拓展沿江的开发空间,提升沿江的产业发展水平。 相似文献

Local governance of energy transition: sustainability,transactions and social ties. A case study in Northeast France 总被引:1,自引:0,他引:1
P. Hamman 《国际发展与全球生态学杂志》2019,26(1):1-10
This paper tackles the process of energy transition from a transactional perspective. It addresses the governance of energy transition by studying its local actualizations, moving beyond purely technical and normative readings. The paper shows that through the local socio-technological energy systems, sustainability governance filters down to the level of individual, everyday behavior, thus questioning the link between public and private spaces, especially regarding the issue of housing. Going beyond the results commonly yielded by transition studies, which favor large-scale analysis, it details how the discourse of citizen involvement, which often boils down to a mere call to control one’s individual energy consumption, conceals environmental inequalities, confirming the socioeconomic divide materialized in deprived areas such as public housing estates or remote rural areas. From a methodological standpoint, the analysis is based on four case studies in Northeast France, in more or less privileged areas, and in both urban and rural environments: the renovation of a heating network in the public housing estate of Cité de l’Ill, north of Strasbourg; the solar energy systems designed for property owners in Plobsheim, a residential suburb of Strasbourg; the energy-efficient equipment set up in a public housing estate in the city of Saint-Dié, in the Vosges; and citizen participation in a cooperative program to finance wind turbines in the small Alsacian city of Saâles, in a mountain rural area. The paper draws on the results of these sociological investigations, carried out using field observations, questionnaires and interviews. 相似文献

The growing interest of stakeholders regarding the contribution of organizations to Sustainable Development is influencing organizational behavior and strategic planning. The purpose of the present paper is to analyze the perception of the importance of organizational sustainability dimensions in a relevant economic sector: the metal industry. Survey data was collected from a sample of 211 Portuguese industries, and non-parametric statistical tests were used to validate five research hypotheses regarding the importance of the economic, environmental, social and cultural dimensions of sustainability. The results obtained demonstrate awareness of the sampled industries regarding all sustainability dimensions, recognizing that their importance has been increasing over the years, and prospecting that this importance will continue to increase in the future. The industries in this sample revealed different degrees of perceived importance for the different sustainability dimensions: the highest importance was given to the economic dimension, and culture was considered the least important sustainability dimension. However, the perception of the respondents is that these differences will be less relevant in the future. The results also show that companies with certified management systems reveal a higher perceived importance regarding sustainability dimensions. Also, industries with higher values of annual turnover, number of employees and export sales tend to give higher degrees of importance to sustainability dimensions. Considering the economic, environmental and social impacts of metal industries at an international level, the awareness of this industrial sector regarding the importance of sustainability is a relevant step to the commitment towards Sustainable Development. 相似文献

The impact of large-scale urban development on land resources has long been debated by urban planners and designers. This study investigated the extent to which different urban characteristics are associated with land-cover change. The Yangtze River Delta region in China, forming one of the largest sprawling urban landscapes among the regions around the world, was chosen for the study area. Spatial analysis and multiple regression methods were applied to empirically investigate the pattern of resource sites lost to urban development in the area between the 1950s and 2017. The results showed that contrary to the widespread notion that large-sized cities are predominantly responsible for a region’s environmental degradation, city size was not a significant factor in determining the rate of resource loss. Large-sized cities gained their populations with far lesser impacts on land than small-sized cities and towns if normalized to the same number of populations. One explanation for the diminishing effect of city size on land-cover change relates to the degree of spatial dispersion of urban development and local differences in social valuation of diversified lands by cities. 相似文献
