Water resource shortage and pollution has seriously threatened the survival and development of developing countries. Because
of China’s specific economical and social circumstances, complete adoption of developed countries’ experience is unrealistic.
At present, China needs to develop strategies and technologies in source water pollution control and municipal environmental
remediation that embrace the country’s specific need to battle the water resource problem. Among them, efficient source water
pretreatment is a critical step to ensure a safe municipal water supply. Unlike developed countries, it is not yet feasible
in China to treat water supplied to the household and have it meet the standard of direct drinking; therefore, it is more
appropriate to refer to it as service water. As a beneficial supplement, an additional community drinking water network and
household drinking water apparatus can be considered. 相似文献

The establishment of the environmental management system in the financial sector can be effectively promoted through the introduction
of the environmental protection concept and its implementation by the financial sector. The impact of a sustainable development
system on the sector is analyzed in this article from three aspects: environmental risk assessment, financing support for
environmental protection projects, and financial services to environmentally friendly corporations and individuals. Influential
factors on the development of the environmental management system in China’s financial sector are discussed from the perspective
of various entities such as financial institutions, financial regulation authorities, environmental protection departments,
corporations, and the public. It is pointed out that China’s financial sector is now in the transitional phase from a defensive
attitude to a preventive attitude. Strengthening governmental guidance, the supervision of regulators as well as public awareness
of environmental protection should be used to enhance the initiative in the development of the environmental management system
in the Chinese financial sector. 相似文献

With the development of rural pollution, its characteristic and institutional factor should be studied for pollution control
through economics and sociology. Based on the data gathered from investigations by several government sectors, rural environmental
pollution can be divided into two types by its sources: internal source type and external source type. The internal source
type is the main component of rural pollution at present, which can be further divided into three types. Research shows that
the contributing institutional factors of rural pollution issues and the effectiveness of environmental management system
over rural pollution can be summarized as distinctiveness. In essence, the rural pollution issue results from the dualism
of rural and urban areas’ inadaptability to rural modernization. In detail, the contributing factors can be summed up on three
institutional levels. There are obvious loopholes in rural environmental management system which, in the meantime, is incapable
and inadaptable to rural pollution control. There exist similar questions in the related public service system, which are
intensified by inappropriate reform which brought about incompatible incentive in the recent years. However, in the eleventh
five-year plan period, there are advantageous trends in the three institutional levels.
Main data sources in this paper: ➀ the surveys on TVEs (township and village enterprises) conducted by Township Enterprise
Bureau of Ministry of Agriculture of China in 1997 and 2002; ➁ the partial survey on rural environmental conditions by EPA
(environmental protection administration) of Zhejiang Province in 2002; ➂ the survey on the pollution of IPLFs (livestock
and poultry farms) in 23 provinces, municipalities, and directly administered cities by the State Environmental Protection
Administration of China in 2002; ➃ the research report on Mechanism of Investment and Financing for Environmental Protection
by China Council for International Environment and Development Cooperation in 2003; ➄ the third investigation on national
hygiene service in 2003; ➅ the regular monitoring of safe quality of agricultural products by the Ministry of Agriculture
of China in 2005; ➆ the investigation arranged by the Ministry of Health which finished in 2007 and showed the total situation
of rural environmental health and drinking water security of the whole country. 相似文献

In developing countries where economies and livelihoods depend largely on ecosystem services, policies for adaptation to climate
change should take into account the role of these services in increasing the resilience of society. This ecosystem-based approach
to adaptation was the focus of an international workshop on “Adaptation to Climate Change: the role of Ecosystem Services”
held in November 2008 in Costa Rica. This article presents the key messages from the workshop. 相似文献

This paper presents the study carried out for controlling agricultural non-point source pollution (NSP) in a medium-sized
watershed covering 1.47 × 104 km2 in Southeast China using quantitative analysis coupled with geographic information system (GIS), universal soil loss equation
(USLE), soil conservation service-curve number (SCS-CN), nutrient loss equations, and annualized agricultural nonpoint source
model (AnnAGNPS). Based on the quantitative results derived from GIS and environmental models, five control division units
were generated for NSP control in Jiulong River watershed, namely, controlling unit for soil losses, controlling unit for
livestock breeding and soil losses, controlling unit for excessive fertilizer use and livestock breeding, controlling unit
for soil losses and fertilizer use, and controlling unit for excessive fertilizer use and soil losses. This study proved that
integrating GIS with environmental models can be adopted to efficiently evaluate major sources and contributors of NSP, and
identify the critical source areas of NSP, which enables adjusting measures to local conditions by further control division
units developed through such study for control and management of water quality degradation induced by NSP in the Jiulong River
watershed.

The rapid growth of China’s economy has led to severe air pollution characterized by acid rain, severe pollution in cities,
and regional air pollution. High concentrations are found for various pollutants such as sulfur dioxides (SO2), nitrogen oxides (NOx), and fine particulates. Great efforts have thus been undertaken for the control of air pollution in the country. This paper
discusses the development and application of appropriate technologies for reducing the major pollutants produced by coal and
vehicles, and investigates air quality modeling as an important support for policy-making. 相似文献

Climate change is one of the most severe global problems in the 21st century. Main drivers are the combustion of fossil fuels,
the emissions of industrial gases, emissions from agricultural sites and animal husbandry as well as deforestation. A new
cooperative climate regime is necessary to meet the World’s energy and environmental problems against the background of China’s
and India’s energy consumption growth. For the second commitment period of the Kyoto Protocol after 2012, a successor regime
has to be agreed on. The current approaches, however, have a common weakness. They at the same time (a) do not acknowledge
the historical responsibilities of the industrialized countries for the historical greenhouse gas emissions and the responsibility
of developing countries for a large fraction of the current future emissions, and (b) do not provide for a fair distribution
of emission rights. Against this background, this article aims at forecasting China’s and India's CO2-emissions up to 2050 and developing a new suggestion for a post Kyoto climate regime based on a cumulated per capita CO2-emission rights taking the weaknesses of the currently discussed post Kyoto approaches into account. 相似文献

The World Year of Physics (2005) is an international celebration to commemorate the 100th anniversary of Einstein’s “Annus
Mirabilis.” The United Nations has officially declared 2005 as the International Year of Physics. However, the impact of Einstein’s
ideas was not restricted to physics. Among numerous other disciplines, Einstein also made significant and specific contributions
to Earth Sciences. His geosciences-related letters, comments, and scientific articles are dispersed, not easily accessible,
and are poorly known. The present review attempts to integrate them as a tribute to Einstein in commemoration of this centenary.
These contributions can be classified into three basic areas: geodynamics, geological (planetary) catastrophism, and fluvial
geomorphology. Regarding geodynamics, Einstein essentially supported Hapgood’s very controversial theory called Earth Crust
Displacement. With respect to geological (planetary) catastrophism, it is shown how the ideas of Einstein about Velikovsky’s
proposals evolved from 1946 to 1955. Finally, in relation to fluvial geodynamics, the review incorporates the elegant work
in which Einstein explains the formation of meandering rivers. A general analysis of his contributions is also carried out
from today’s perspective. Given the interdisciplinarity and implications of Einstein’s achievements to multiple fields of
knowledge, we propose that the year 2005 serve, rather than to confine his universal figure within a specific scientific area,
to broaden it for a better appreciation of this brilliant scientist in all of his dimensions. 相似文献

Practical approaches to pollution control have involved the determination of an environmental quality standard and the use of various policy instruments, market or non-market, to achieve this desired standard. These ideas have been developed to deal with point source pollution, polluter and pollutant being identifiable. However, environmental problems arising from agriculture tend to involve nonpoint source and, often, indirect pollution. Animal wastes, in particular, have certain characteristics which pose especial problems for pollution control, both in determining and in achieving an environmental standard.In this study, a basis for a standard is suggested, and an animal waste management scheme is proposed which, it is hoped, could be effective in achieving this standard. A linear programming framework is explained for comparing this scheme with alternative pollution control policies in terms of efficiency and changed patterns of agricultural production. 相似文献

In an attempt to better understand the mechanism underlying lateral collision avoidance in flying insects, we trained honeybees
(Apis mellifera) to fly through a large (95-cm wide) flight tunnel. We found that, depending on the entrance and feeder positions, honeybees
would either center along the corridor midline or fly along one wall. Bees kept following one wall even when a major (150-cm
long) part of the opposite wall was removed. These findings cannot be accounted for by the “optic flow balance” hypothesis
that has been put forward to explain the typical bees’ “centering response” observed in narrower corridors. Both centering
and wall-following behaviors are well accounted for, however, by a control scheme called the lateral optic flow regulator, i.e., a feedback system that strives to maintain the unilateral optic flow constant. The power of this control scheme is
that it would allow the bee to guide itself visually in a corridor without having to measure its speed or distance from the
walls. 相似文献

工业VOCs经济手段和工程技术减排对比性分析 总被引:2,自引:1,他引:1
挥发性有机物(VOCs)污染已经同二氧化硫、氮氧化物和颗粒物等成为目前我国重点城市群的主要大气污染物.工业领域是挥发性有机物的主要排放部门,工程技术减排是重要的控制措施之一."十二五"期间,我国计划投资400亿元建设重点行业挥发性有机物污染治理项目,年减排量计划为60.5万t·a-1.技术减排被提到了一个新的高度,表明了国家对工程技术减排的重视.本研究采用宏观经济学可计算的一般均衡模型,对工程技术减排与经济手段(环境税)进行政策模拟,进行比对性分析,探讨了两种减排方法的优劣.研究认为,当前经济条件下,相同减排量下,考虑宏观经济损失,环境税减排的成本远高于技术减排.结合目前我国实际情况,为鼓励工程技术减排,建议政府给予企业约为7 500元·t-1的财政补贴. 相似文献
