基于PSR模型的中国大气污染防治技术推广效果评价     

李重阳  江磊  刘兆香  王京 《科技管理研究》2021,(8)

为量化评估我国大气污染防治技术推广效果,本文基于“压力－状态－响应” (PSR)模型原理,首次构建了中国大气污染防治技术推广效果评价指标体系,测算了2005-2017 年中国大气污染防治技术推广综合指数,评价了技术推广效果,并采用灰色关联度法分析各指标关联度。结果显示,技术推广综合指数由2005年的0.13快速增长到2014年的0.69后略有下滑至2017年的0.62,技术推广效果逐步趋于良好。技术市场成交额、政策引导、科研和开发机构研究与试验发展人员是影响技术推广效果最主要的三个因素。指标体系为量化评价大气污染防治技术推广效果,提出促进技术推广的建议提供了技术方法和科学依据。  相似文献

SWAT模型简介及其在非点源污染研究中的应用     

王玉合  张贵文 《科技广场》2008,(5)

非点源污染是现代环境科学研究的热点之一,SWAT模型作为一种分布式流域尺度水文模型,能有效模拟土壤侵蚀和水土流失,地表水和地下水污染情况,进行水资源评价和管理等,是进行非点源污染模拟的有效工具。本文在参阅前人文献的基础上,就SWAT模型进行非点源污染模拟的机理,以及模型在国内外的应用情况和取得的成果进行了一些简单的介绍。  相似文献

Federalism in the Regulation of Chemical Pollutants in Australia     

《普罗米修斯》2012,30(2):247-264

In response to the growth of the environment movement and increasing citizen concern for the environment, the Commonwealth and the Australian states moved to set up government departments of environment, or Environment Protection Agencies, in the early 1970s. At first the issues which engaged the public were 'green' ones, involving land and marine degradation, biodiversity (a term not then in use), and activities such as logging, mining and the generation of hydro-electric power. These were soon joined on the public agenda, however, by concerns over 'brown' issues such as chemical pollution and the management of hazardous chemicals and chemical wastes, but these were less well understood by the general public than the more visible 'green' issues. At this time, also, Australian governments took significant steps to achieve nationally consistent regulation through the work of ministerial councils, notably the Australian Environment Council (AEC) and subsequently the Australian and New Zealand Environment and Conservation Council (ANZECC). A further wave of environmentalism in the late 1980s and early 1990s, coupled with further development of the federalism model for environmental regulation that flowed from high-level inter-government meetings that were formalised as the Council of Australian Governments (COAG), gave rise to the formation of the National Environment Protection Council (NEPC). This body, while not giving more power to the Commonwealth, achieves national harmonisation of regulations through slightly more coercive processes than are available to the older-style ministerial councils. These continue to exist, however, operating in parallel with NEPC. For chemicals coming into use, there are national schemes under which the Commonwealth, states and territories regulated industrial, agricultural and veterinary chemicals, therapeutic substances, and food additives. Most 'brown' issues, however, remain with the successor to ANZECC, the Environment Protection and Heritage Council, as part of which NEPC continues to develop national approaches. In both periods of rapid change, there was a coincidence of environmentalism and federalism, but international developments were also important--in the first phase the United Nations' first 'environment' meeting, held in 1972 in Stockholm, and in the second the developments flowing from the so-called 'Earth Summit' held in Rio de Janeiro in 1992. Although public environmentalism continues to be mainly concerned with 'green' issues, the 'brown' issues remain a focus for governments and some non-government organisations.  相似文献   

旅游者排污行为与旅游区水环境干扰模式研究——以六盘山生态旅游区为例   总被引：1，自引：0，他引：1  

赵美风  席建超 《资源科学》2012,34(12):2418-2426

旅游活动是生态旅游区短时段区域性水环境变化的主要驱动因素。本文以六盘山生态旅游区为案例区,通过参与式观察、问卷调查和比较分析,研究了不同类型旅游者旅游排污行为及其水环境干扰模式。结果表明:①从旅游活动环节看,住宿活动污染物排放量最高,餐饮其次,游览最低;②从游客类型看,在人均干扰程度方面,以下四类游客的旅游活动干扰综合指数(TADI)依次降低:商务会议(1)>休闲度假(0.57)>科学考察(0.19)>观光游览(0);在总干扰程度方面,以下四类游客的TADI依次降低:休闲度假(1)>商务会议(0.51)>观光游览(0.33)>科学考察(0);③商务会议、休闲度假、科学考察和观光游览四类游客对住宿和餐饮要求依次提高,日排水量依次增多。六盘山处于重要的战略转型期,商务旅游、休闲度假将成为未来发展重点,旅游区水环境问题将更为凸显,因此,必须重视这种转型升级可能引发的旅游区水质恶化问题。  相似文献
