我国湿地景观研究进展 总被引:1,自引:0,他引:1
《中国环境管理干部学院学报》2018,(5)
湿地景观的变化和健康状况对湿地的过程和功能有着重要的影响。在对湿地景观概念进行明确界定的前提下,系统梳理我国湿地景观的研究尺度和研究现状,重点阐述湿地景观格局和景观健康相关的研究理论、方法和成果,对景观格局指数法、景观动态表征模型、指标体系法和景观强度法等相关研究方法的适用范围及优缺点进行探讨。在此基础上,指出湿地景观未来的研究可以尝试采用多种评价方法进行综合评价,更加注重对湿地景观进行科学的分类。 相似文献

全国统一的污水排污费征收最近开始实施。这是对污染物实施排放总量控制的一项重要政策。 为了控制日益严重的工业污染,保证国民经济的持续发展,我国对污染物的控制已由过去的以浓度控制为主转向总量控制和浓度控制并重。征收污水排污费的标准和有关政策,是根据《中华人民共和国环境保护法》《中华人民共和国水污染防治法》的有关规定,由国家环保局会同国家物价管理部门和财政部制定的。 据介绍,污水排污是指排污单位向水体排放的废水,虽未超过国家或地方规定的污染物排放标准,但增加了污染物的种类、浓度或数量,按照规定每排放1吨污水收费0.05元。向水体排放污染物超过排放标准的,仍按现行规定征收超标排污费,不再重复计征污水排污费。 相似文献

ABSTRACTSmart and eco-cities have become important notions for thinking about urban futures. This article contributes to these ongoing debates about smart and eco-urbanism by focussing on recent urbanisation initiatives in Asia. Our study of India’s Smart Cities Mission launched under the administration of Narendra Modi and China’s All-In-One eco-cities project initiated by Xi Jinpin unfolds in two corresponding narratives. Roy and Ong’s [2011. Worlding Cities: Asian Experiments and the Art of Being Global. Oxford: Wiley-Blackwell] “worlding cities” serves as the theoretical backdrop of our analysis. Based on a careful review of a diverse set of academic literature, policy and other sources we identify five process-dimensions for analysing the respective urban approaches. We show how the specific features of China’s and India’s urban focus, organisation, implementation, governance and embedding manifest both nations’ approaches to smart and eco-urbanism. We argue that India’s Smart City Mission and China’s All-in-One project are firmly anchored in broader agendas of change that are set out to transform the nation and extend into time. The Indian Smart City Mission is part of a broader ambition to transform the nation enabling her “smart incarnation” in modernity. Smart technologies are seen as the key drivers of change. In China the framework of ecological civilisation continues a 5000-year historical tradition of civilisation excellence. By explicitly linking eco-urbanism to the framework, eco-cities become a means to enact ecological civilisation on the (urban) ground. 相似文献

Private and public interests in water and energy 总被引:1,自引:0,他引:1
Based on empirical evidence from developed, transition and developing countries, the article looks at how the introduction of private operators’ interests into the water supply/sanitation and energy sectors may conflict with public interests in socio‐economic, environmental and political dimensions. Case studies are used to illustrate the dynamics of these interactions, covering phenomena such as unsolicited proposals, misrepresentation and corruption; the exploitation of established positions by taking advantage of asymmetry of information and negotiating capacity in relation to public authorities; and exit from contracts or concessions when acceptable profitability cannot be attained. This experience indicates that the introduction of private companies into these sectors creates the permanent possibility of conflict between private and public interests. The services are too vital both socially and economically to rely on corporate self‐regulation, and countries lack effective capacity to regulate such corporations. The authors conclude that policies relying on corporate activity in these sectors are unnecessarily risky, and that policy development should focus on building strong public sector institutions to provide these services. 相似文献

Joseph Murphy 《Local Environment》2013,18(7):801-816
This paper reflects on two controversial resource projects – the Bellanaboy gas refinery (Ireland) and the Barvas Moor wind farm (Scotland) – and critical arguments made by key local actors. Although risk, health, environment and development dominated the official decision-making processes, these actors articulated views which cut across or existed beyond such orthodox ideas and framings. Focusing on these, I show that the Gaelic concepts of dùthchas and deoraíocht, summarised as place and exile, help to explain why some residents decided to protest. This paper illustrates the role that history, culture and language can play in conflicts, emphasises the need for greater sensitivity to these and suggests that place and exile can inform alternative visions of sustainability. 相似文献

Indirect, unpriced environmental and social costs of human activities in the United States amount to several trillion dollars each year. By accounting for these costs and shifting some of the tax burden from work to waste, it would be possible to protect the environment and benefit society and the economy. 相似文献
