Water resources optimization and eco-environmental protection in Qaidam Basin

In order to realize sustainable development of the arid area of Northwest China, rational water resources exploitation and optimization are primary prerequisites. Based on the essential principle of sustainable development, this paper puts forward a general idea on water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources optimization. By some qualitative methods such as Input-output Model & AHP Model and some quantitative methods such as System Dynamics Model & Produce Function Model, some standard plans of water resources optimization come into being. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.

Analysis of the Status and Rational Allocation of Water Resources in China in View of the New Era

This paper examines the current status of water resource management and conservation in China,along with strategies to address the water resource crisis.Given the current situation,the paper highlights issues such as incomplete legal mechanisms,limited environmental awareness among enterprises,and insufficient government investment.To ad-dress these challenges,the paper proposes a series of strategies,including improving the ecological environment,enhanc-ing production techniques,strengthening management systems,rationalizing water resource allocation,and implementing water-saving measures in both industrial and agricultural production.These strategies serve to achieve sustainable water resource management,reduce water pollution,and effectively tackle the pressing water resource issues faced in China currently.

Environmental Protection of Biodiversity in Macedonia and Albania under Legal Analysis View

Environmental problems in the Republic of Macedonia and Albania are similar in other countries in the region. Numerous problems and deficiencies identified through different projects. The studies and planning documents are evident for environmental media and areas. Such as lack of regional integrated systems for municipal solid waste management. The system for special waste types management, including hazardous waste, insufficient coverage of populated places and municipalities by wastewater collection and treatment systems （especially in agglomerations above 10,000 populations）. The need to establish integrated river basin management is in accordance with the new law on waters, air pollution with different intensity in different parts of the country. This paper presents the imperative reforms to protect the natural resources and biodiversity in the countries.

Develop hydroenergy resources and protect earth environment

Energy is a driving force behind the progress of human civilization. Mainly depend on the current human society of non-renewable fossil energy sources, such as coal and oil, its increasing demand. Gradually reduce the reserves, the contradiction between supply and demand becoming increasingly prominent. With the process of human history has moved forward with the depletion of fossil energy will eventually be unable to sustainable use. The total hydropower resources are limited, but it is renewable, clean energy, its energy is infinite. Therefore, the full use of limited water resources and slow down the depletion of fossil energy process, is to improve and protect the earth’s ecology and environment, one of the most realistic measures.

Discussion on Influencing Factors of Water Resources Environment and Strategies for Protecting Water Ecology

At present,the major problems facing the water resource environment worldwide include water pollution,water resource shortage,and water ecosystem degradation.The discharge of industrial wastewater,agricultural non-point source pollution,and the discharge of urban sewage lead to a serious decline in water quality,which directly affects the safety of human drinking water and the living environment of aquatic organisms.Additionally,the unbalanced distribution and excessive exploitation of water resources lead to the problem of water shortage in many areas,which then leads to social and economic contradictions and ecological crises.In terms of ecosystems,the phenomena of water ecological degradation and reduction of biodiversity are increasingly obvious,and the carrying capacity of aquatic ecosystems are gradually declining.This paper aims to analyze the natural,social,and economic factors affecting the water resource environment,and propose effective strategies to protect the water ecology.To provide a theoretical basis and practical guidance for the sustainable utilization of water resources and the long-term development of the water ecosystem.

Combination of drainage, water supply and environmental protection as well as rational distribution of water resource in Zhengzhou mining district

The geological condition of coalfield is much complex in China. With increasing in mining depth and drainage amount, the contradiction of drainage, water supply and environ-mental protection is becoming more and more serious. However, the contradiction can be solved by the scientific management of optimizing combination of drainage, water supply and environ-mental protection. The Philip multiple objectives simplex method used in this article has searched for a possible solution at the first step, and then it goes on searching to find out whether there is a weight number that can lead the solution to the biggest. It can reduce the randomness and diffi-culty of traditional weight method which determine the weight number artificially. Some beneficial coefficients are vague and the number is larger in the model of water resource dispatch. So the vague layer analysis method can consider these vague factors fully, combining the qualitative and quantitative analysis together. Especially, this method can quantify the experiential judge-ment of policy decider, and it will turn to be more suitable if the structure of objective factors is complex or the necessary data are absent. In the paper, the two methods above are used to solve the plans of drainage, water supply and optimizing distribution of water resource in the Zhengzhou mining district.

A holistic approach to creating a new yangtze river basin protection legislation

The protection of the Yangtze River Basin is a top priority in China,and the National People's Congress(NPC)Standing Committee has started to draft a new protection legislation specifically for the Yangtze River Basin.The Basin forms the epicenter of environmental,social,and economic life.Any efforts to protect the Basin must accommodate several competing interests from a multiplicity of interested parties and stakeholders such as local governments,villages,and business enterprises.Current relevant institutions and organizations are unable to sufficiently ensure environmental protection and green development in the Basin.The NPC Standing Committee must thus adopt a more holistic approach when creating new protection legislations aimed at the Yangtze River Basin.

自然资源问责审计对水污染治理效率的影响研究

作为一项重大的改革措施,领导干部自然资源资产离任审计(简称“自然资源问责审计”)在推进环境保护、资源节约方面具有重要作用。基于2005—2017年我国271个城市的面板数据,使用双重差分模型考察自然资源问责审计与水污染治理效率之间的关系。研究表明:自然资源问责审计的实施显著提高了水污染治理效率,经过一系列稳健性检验,结果依然成立。进一步研究发现,中央环保督察是自然资源问责审计提高试点城市水污染治理效率的调节机制。在南方地区与水污染治理效率较低的地区,自然资源问责审计发挥的作用更加显著,且与动态面板数据估计方法的结果与之吻合。因此,加强自然资源问责审计结果运用、强化地方官员水污染治理主体责任意识、实施动态的差异化政策,有助于推动我国水污染防治。
