Three key problemsrelated to water resources and security issues in North China in the 21st century are addressed, namely 1) the watercycle under environmental change, 2) agricultural water saving, and 3) water security. Development of internationalresearch related to these issues is also reviewed. The research plan developed recently by the Chinese Academy of Sciences(CAS) is discussed and suggestions on research and development of water resources science in North China are presented.Thanks to focus on experimental catchments and dedicated research stations, a detailed knowledge of the water cycle onNorth China farmland has been compiled. A range of techniques that include isotope tracers has been used to acquirehydrologic data. Much research has been devoted to developing distributed hydrological models at different scales. In thewell irrigation district, five different water saving irrigation regimes have been investigated, and these regimes have hadwidespread application, and reduced water use 60-150 mm while they increased water use efficiency (WUE) by 20%-30%.Furthermore, preventing water pollution is the most essential step to ensure North China’s water security.展开更多

Such targets are often the key objective of an environmental policy, such as an emission trading program. In China, however, it is more than just an objective of one particular policy; it has become a concept that has influenced many national environmental policies and activities. The objective of this article is to review the implementation of the total emission control policy in the past 10 years and explore emerging issues in its implementation. The article has three sections: a summary of the implementation experience, issues with the design and implementation of the policy, and policy recommendations.展开更多

In Europe, this concept is implemented from the local to tha nation, even to the Continent. The local sustainable development mainly consists in two factors： one is the renovating method continually invented by European Secretariot of ICLEI, and the other is that the local authorities towards sustainability are co-operated by the European Sustainable Cities and Towns Campaign. The coo-budget method is the outcome of tbese factors, For our country is a big country, on rapid progression of indastrialization and urbanization, with a large population and scarce resoarces per capita, it is practically significance to study us soon as possible the methodology. Experience from European local sustainable development may help us to resolve the handicap of departraent division in local a, tbority.展开更多

The first part will introduce ecocentrism, eco.centric management, and one major way to achieve eco-centric management in reality. Second. the environmental regulations of United Nation （UN） and China will be analyzed and compared to find out whether they are eco-centric. Moreover, the implementation of environmental regulation in China will be analyzed because regulatitm cannnt exist without proper implementation. Three suggestions were given to improve eco-centric management in China： natural science research and public administration, environmental education, international cooperation.展开更多

Scenario analysis of GDP is performed using the GDP model established in the paper. The energy consumptions in Germany, Japan and other developed countries are analyzed and compared with the energy consumption in China. Environmental friendly scenario of energy demand and CO2 emissions for sustainable China has been formed based on the results of comparison. Under environmental friendly scenario, the primary energy consumption will be 4.31 billion ton coal equivalence （tee） and CO2 emissions will be 1.854 billion t-c in 2050; energy per capital will be 3.06 tee that is 1.8 times of energy consumed in 2005 in China and 51% of consumed energy per capital in Japan in 2003. In 2050, the energy requirement of unit GDP will be 20% lower than that of Germany in 2003, but will be still 37% higher than that in Japan in 2003. It is certain that to fulfill the environmental friendly Scenario of energy demand and CO2 emissions is a difficult task and it needs long term efforts of the whole society, not only in production sectors but also in service and household sectors,展开更多

For example, China＇s recycling policies appear paradoxical. With its rapidly expanding economy, China is now the world＇s largest emitter of urban waste. Under such a situation, China is aiming to build up a recycling economy by enacting a number of related laws. Despite the development of waste recycling regulations, however, the load on the environment by continuously increasing waste has not reduced in China so far. What explains this seemingly paradoxical situation of waste recycling in China？ It has been pointed out in the previous study on China＇s climate change policies that environment protection falls under the rubric of sustainable development in China. The question here is whether the same story can be applied to areas other than climate change in China＇s environmental management. This paper examines it in the area of its waste recycling policy. This paper conducts an evaluation of waste recycling regulations in China by comparing it with the experience of Japan, China＇s next-door advanced country. It concludes that the waste recycling regulations in China do not primarily aim at reducing the environmental load by reducing the amount of waste but rather for the main purpose of recycling and reusing resources effectively for the sake of economic development.展开更多

There is growing concern about whether PWS programs have achieved their original environmental goals of improving water quality and quantity, as well as the ancillary objective of increasing the welfare of local people. We start with an overview of PWS schemes and focus on their particularity and implementation mechanisms in China. We proceed to review 62 active PWS cases and examine their environmental performance in detail. The resulting findings show that PWS schemes have been able to reduce water pollution to some extent by establishing collaborative upstream/downstream watershed management policies, thereby improving water quality and quantity, as well as by making government officials more responsible for water resource management. In addition, their continued effectiveness in light of present challenges such as water-quality data availability is discussed. Chinese PWS schemes and their implementation mechanisms also provide information useful in monitoring environmental outcomes and guiding future designs of PWS programs in other regions.展开更多

As one of the important factors threatening human security, global environmental change has become a new challenge to the national security and social development. The national security problems caused by global environmental change, on one hand, are closely related to the global environmental problems, and, on the other hand, are manifested in the conflicts of international affairs. The global environmental change severely challenges the future development of China. When it comes to the study on human dimensions of global environmental change in China, much more attention should be paid to issues of important environmental change that may have great impacts on the national security of China, to the scientific assessment of the vulnerabilities of the natural and socialeconomic system of China to the impacts of global environmental change, and to the active establishment of the national risk management system, in which global environmental change should be included, so as to make contribution to sustainable development and construction of harmonious society of China.展开更多

The purposes of such policies are： to accelerate the reform of mineral resource royalties and advance the competitive transfer of mining rights; to promote the reform of the natural gas price, introduce cost supervision on long-distance natural gas pipeline enterprises in the area of gas pipeline transportation, and strengthen the regulation qf the distribution price; to liberalize the import qf crude oil in an orderly manner, increase the allowable volume of non-state trading crude oil imports, strengthen the supervision and periodically pause the approval of the right to use imported crude oil; and to enhance environmental protection.展开更多

文摘The concept of security has been redefined since the 1990s. As one of the important factors threatening human security, global environmental change has become a new challenge to the national security and social development. The national security problems caused by global environmental change, on one hand, are closely related to the global environmental problems, and, on the other hand, are manifested in the conflicts of international affairs. The global environmental change severely challenges the future development of China.
