“…The local equilibrium points obtained by solving the replicator dynamic equation is not necessarily the ESS points. According to the values in Table 2, for the local equilibrium point (x*, y*), it is obvious that A 11 + A 22 = 0 can be obtained which does not meet the trace condition of Formula (9), and it can't meet both conditions ( 9) and (10), therefore, this point is not the ESS point of the system I. Thus, we only need to analyze the determinant and trace at local equilibrium points (0, 0), (0, 1), (1, 0) and (1, 1), and accordingly analyze the stability of system I.…”

“…Currently, research literatures on this topic are predominantly concentrated on mining environmental ecological restoration technologies, methods, benefits of soil ecological restoration in mining areas and quality evaluation of restoration [2][3][4][5][6][7][8][9]. In recent years, attention has also been directed towards the goals and directions of abandoned mine site restoration, marketoriented operation of restoration projects, government regulations, measures and management methods in this process [10][11][12]. Due to the disorderly development and utilization of mines in the early stages in China, a considerable amount of environmental pollution has been generated without clear responsibility attribution.…”

There is a huge funding gap in the abandoned mines ecological restoration in China. It is of great research value to explore how PPP model can better introduce social capital into the low-profit ecological restoration of abandoned mines. Based on the innovation perspective of the central government’s reward and punishment system, this paper constructs an evolutionary game model of "local government-social capital", analyzes the interaction and behavior mechanism of core stakeholders in the operation process of abandoned mines ecological restoration PPP mode, and discusses the influence of evolutionary equilibrium strategy and parameters change on evolutionary strategy under different scenarios by Matlab simulation. The research shows that the abandoned mines ecological restoration needs the support of the central government. When the local government lightly punishes the low-quality service of social capital, the central government needs to pay higher costs to promote all parties to actively participate in the operation and supervision of the PPP project. The revenue and cost of government supervision, the operating subsidy for social capital and the cost saved by social capital in providing bad service are the key factors affecting the evolution of the game between government and social capital. Punishment can effectively spur social capital to keep the contract and operate in the project, but the punishment effect will be ineffective without government supervision. Finally, some suggestions are put forward, such as establishing a long-term supervision mechanism and a reasonable income mechanism for PPP projects, increasing penalties for violations, attracting third parties to reduce supervision costs and strengthening communication between the two parties, so as to make the project take into account the economic performance of social capital and the social welfare of government departments, and achieve dual Pareto improvement.

“…Besides its enormous amount, the management and disposal of fly ash are inappropriate, leading to further deterioration of water and soil environments. Moreover, the excessive mining of stone materials and coal resources depletes resources, so mine environments urgently need structural restoration (Li and Lin, 2022;Zhang et al, 2022). Therefore, large-scale application and utilization of industrial solid waste fly ash (Mathapati et al, 2022) are of particular importance and may solve environmental problems and help restore sensitive localities.…”

Effects of different factors on fly ash-based functional soil and its oat grass cultivation

et al. 2022

Using fly ash as the main matrix for plant ecological restoration is effective for constructing a sustainable and ecological environment. The relevant properties of functional soil change due to different factors. Based on the orthogonal experiment of functional soil and the pot experiment of oat grass, fly ash was used as the matrix material for functional soil. Afterward, MX (large granules dispensing certain nutrients), SJJXWS (a water-retaining agent), and AF (a nutrient conditioner) additives were added to study the physical, chemical, and agronomic properties of functional soil, such as the emergence rate and weight of plants. The results showed the high pH and conductivity of functional soil, implying alkaline soils with high salinity. The contents of organic matter and available phosphorus and potassium were relatively high, indicating its high nutrient content. Further analysis revealed that the MX was the key factor affecting functional soil’s electrical conductivity and evaporation, and thus, the corresponding plant emergence rate, plant weight, and other related indicators. The influence of each factor on the corresponding plant emergence rate, plant weight, and other indicators of functional soil was arranged in the order of MX (large granules dispensing certain nutrients), SJJXWS (a water-retaining agent), and AF (a nutrient conditioner). The optimum additive ratio in functional soil was 0.45 t·hm-2 of MX, 0.12 t·hm-2 of SJJXWS, and 1.65 t·hm-2 of AF. The results of this study provide a theoretical basis for further development of functional soil for ecological cycle restoration purposes.

With the development of digital technology, the curriculum design of art majors is also quite different from traditional courses. With the continuous development of information technology and the continuous maturity of campus network technology, teaching resources have become an important part of information resources. High-quality teaching resources play an important role in improving teaching quality and excavating educational development potential. However, traditional classroom teaching is difficult to meet people’s needs. In the context of the current new normal, the way of social and economic management has changed. On the one hand, traditional course teaching resources store information in the forms of paper lesson plans, PPT courseware, discrete pictures, and video files. These forms of storage are not conducive to the distribution and sharing of resources. On the other hand, these teaching resources are scattered among the teaching teachers. As the curriculum develops, the courses taught by teachers change. Because schools lack effective means for unified management, these teaching resources are easily lost. The used method is not conducive to the accumulation of teaching resources or the continuation and development of courses. In order to present good results, these materials usually occupy a large amount of storage space. Therefore, some existing information-based teaching platforms cannot meet the demand. We use network and web technology to develop a teaching file management system, which is very necessary. This paper firstly compares the mature teaching resource management system on the market and some problems in its professional application. Secondly, the article analyzes the actual situation of teaching resource management of art design majors in China and generally describes the system development background and technology. Then, the paper analyzes the requirements of the system in detail by using the object-oriented method and gives the overall design and implementation method of the system. These methods include the use case diagram of the subsystem, the flow chart of the main module, the system architecture, and the design and application of UML. Finally, this paper designs a test case for the teaching resource management system.
