Although the construction of water conservancy projects has promoted economic development, it has also caused great damage to the social environment to a certain extent. Research on water conservancy project construction is of great significance for promoting sustainable development. This article first deeply studied the relationship between water conservancy project construction and environmental protection, then put forward constructive opinions on how to plan water conservancy project construction scientifically and rationally, and finally carried out simulation experiments using examples. The experimental results show that the method proposed in this article can effectively reduce the environmental impact of water conservancy project construction and promote economic growth.

Industrial enterprises are the foundation of the real economy and an important support for building strategic advantages for future development. The industrialisation process has created unprecedented material wealth for our country, but also produced irreparable environmental pollution. To comprehensively and objectively reflect the sustainable development ability of industrial enterprises, an evaluation method of green competitiveness for industrial enterprises is proposed. First, the construction principle of evaluation indices is put forward, and then the evaluation indices system of green competitiveness for industrial enterprises is constructed. In addition, in order to highlight the democratic characteristics of decision-making, an evaluation method of green competitiveness based on stakeholder perspective is proposed. Moreover, the green competitiveness of industrial enterprises in 14 cities is evaluated by using the evaluation method. Finally, the development countermeasures are put forward to promote the green competitiveness of industrial enterprises based on the evaluation results.

This article aims to study the environmental protection issues of world cultural heritage sites from the perspective of circular economy. This article uses big data analysis methods, using surveys, interviews, statistics and other techniques to investigate people's understanding of the circular economy and the environmental protection of world cultural heritage sites. The results show that about 55% of college students have only a little understanding of circular economy, about 58% of college students believe that the environmental protection of world cultural heritage sites is very necessary; at the same time, 64.5% of people can fully realise the importance of environmental protection. In addition, most people believe that the environmental protection of world cultural heritage sites can effectively protect world cultural heritage, promote economic development, sustainable social development, and improve social civilisation.

With the further development of industrialisation and urbanisation, urban environmental problems have become increasingly prominent. How to achieve the integration and integrated development of urban environment and economy on the basis of maintaining sustainable development has become an urgent problem to be solved. This paper takes Jiangxi Province as an example, and uses the grey relational analysis method to explore the problems existing in the development of Jiangxi Province's product-oriented cities. The research results show that from 2011 to 2019, the degree of industrial integration in Jiangxi Province increased from 0.312 to 0.770, showing a clear growth trend. This article concludes that the sustainable development of the environment is negatively related to industry, and only by integrating industrial integration and promoting the upgrading of industrial structure can the integrated development of cities be realised.

Fully mechanised caving mining is widely used because it can quickly convert coal resources into productivity advantages. The water resources of Bayangol coal mine is scarce and the vegetation coverage rate is low. The evolution of the water flowing fracture zone in overburden strata under the fully mechanised caving mining conditions is unknown, and the impact on the ecological environment cannot be predicted. Therefore, this paper took the 311101 working face as the research object, adopted theoretical analysis, FLAC3D numerical simulation and other methods to carry out the study on the evolution of water flowing fracture zone in fully mechanised caving mining in Bayangol coal mine. Through the integrated application of different methods, the development height of the water flowing fracture zone of 311101 working face is determined, and the evolution of the water flowing fracture zone in overburden strata of the fully mechanised caving mining in Bayangol coal mine is preliminarily revealed, which provides guidance and reference for the subsequent working face mining.

The water rights market has not yet been developed, water rights transaction system has not yet been formed in China. To solve these problems, the current states of water rights in China are outlined at first. At second, taking the Yellow River Basin of Inner Mongolia as a case study, the water rights transaction system in the Yellow River Basin of Inner Mongolia Autonomous Region is introduced. At last, the system are evaluated from the aspects such as water rights transaction parties, tradable water rights, transaction procedure, transaction price and transaction period. It is conducive to promoting the construction of a fair and orderly water rights transaction market with Chinese characteristics, and provides decision-making reference for improving China's water rights management system.

The paper aims to highlight the importance of renewable energy in the contemporary world facing a range of environmental challenges. It brings out the conceptual, theoretical and methodological use of alternative fuel through an experimentation conducted in our research institute. The present work involves the energy and exergy analysis of a 5.9 kW diesel engine fuelled with diesel and WPE10 [10% of low-density polyethylene (LDPE) oil blended with 90% diesel by volume]. The LDPE oil was obtained at optimum condition of kaolin catalysed pyrolysis method. The analysis was conducted on per mole of fuel and on stoichiometric basis. The energy and exergy analysis was carried out by using 1st law and 2nd law of thermodynamics, respectively. The energetic and exergetic performance of WPE10 resembles with the diesel fuel which can be a substitute as an alternative fuel. The use of plastic waste for creating fuel is a step towards plastic waste management. The attempt of this paper is for a larger contribution to sustainable development.

Of late, the permanent magnetic actuator has been used widely in the vacuum circuit breaker. The permanent magnet mechanism explored in this paper adopts the NdFeB permanent magnet. An important indicator of its reliability is the mechanical life of the vacuum circuit breakers (VCBs). In this study, 12 KV permanent magnet-operated VCBs have been tested for their mechanical fidelity. With the degradation failure following the Gaussian process and the traumatic failure of the Weibull distribution, the competition failure model has been established by considering the correlation between the two failure modes. The model parameter estimation was determined using the EM algorithm. Eventually, the reliability of the model was attained. This paper evaluates the results of different methods have been compared and analysed, which further proved that the method proposed in this paper had better evaluation accuracy and certain specific value for engineering application.

In order to study the influence of plow pan on water infiltration in dry land, a series of experiments were carried out with soil blocks, water and Mariotte bottle. The experimental results indicate that: 1) the Kostiakov model, Horton model and Philip model all apply to describing the relation between accumulative infiltration capacity and infiltration time in various experimental situations of this study, and the minimum of correlation coefficient R2 can reach to 0.991; 2) the plow pan structure existing in the soil has an evident infiltration resistant and reducing effect on the distribution of infiltrated water. The research conclusions further show the influencing rule of plow pan on the infiltration process of water and its distribution. This research provides a basis for scientific design of irrigation systems and schedules, improves irrigation efficiency, and gives guidance to the breaking down of plow pan in agricultural production.
