Referencing the relevant technical specifications of the International Civil Aviation Organization (ICAO), the current state of airspace usage and flight procedures naming in China was analyzed. A new approach to flight procedures design and naming is proposed. This approach introduces the concept of transition+common segment (point) and integrates parallel runways with arrival and departure paths, significantly reducing the number of flight procedures and aeronautical charts, thereby improving airspace utilization efficiency. Using Chengdu Shuangliu Airport as an example, the application of the transition + common segment (point) concept at this airport was analyzed, demonstrating its effectiveness in reducing the number of flight procedures, simplifying aeronautical charts, and easing the burden on air traffic management.

As a backup means of radar control, procedural control plays an important role in case of radar failure. It is very important for controllers to master procedural control skills. To this end, a Python-based procedural control conflict detection and deployment auxiliary teaching system was designed and implemented. Firstly, a seven-layer architecture is designed, covering the user layer, presentation layer, business layer, model layer, data layer, operating system layer and hardware layer. Then, five core modules are constructed: interactive interface module, data preprocessing module, conflict detection module, dynamic conflict display module and conflict deployment module, and the functions and implementation technologies of each module are designed in detail. Finally, taking the actual teaching scenario of Wuhan Nanhu Airport approach control airspace as an example, Python was used to simulate and verify the system. Students can use the system to automatically detect conflict types and propose conflict solutions, so as to better master conflict deployment skills.

Due to the excessive mining and the lack of perfect and suitable mine restoration measures, some villages in Xintai area have coal goaf and karst collapse area. Through field investigation and public opinion survey, GIS(geographic information system)technology and Origin comprehensive three types of eight evaluation factors were used to evaluate the mine geological environment. With the engineering rock group stratigraphic lithology as the base map for the evaluation of the geological environment of Xintai major coal mining and hollowing township geological environment grade mapping, the results show that the mine environment in Xintai area is average. According to the evaluation results, targeted restoration and ecological management can be carried out in Xintai area according to the township as a unit. After using GIS and Origin and synergy matrixcalculation methods to evaluate the mine environment of each township in Xintai area, it is found that the mine geological environment quality of Wennan Town is relatively the worst, and the evaluation grade is poor, while the results of other township grades are average. Mine ecological restoration and land ecological utilization are important environmental protection measures, and it is recommended to restore the mine environment, organize land and carry out urban planning through vegetation restoration and greening, soil improvement and conservation, rational use of water resources, protection of biodiversity, land reuse and comprehensive development, and structural gradient restoration.The research method can be applied to the geological environment assessment of other mines.

CiteSpace was used to visually analyze the hot frontiers and development trends of research on the coordination of science, technology, economy, and ecology in China’s CNKI journal literature. The distribution of institutional and author collaborations, co-occurrence and emergence analysis of hot keywords, as well as hot topics were systematically sort out. It is found that there has been a significant increase in relevant literature after 2015, forming a core author group, but no representative university institutions have been formed. The research hot keywords include “economic growth”“environmental regulation”“technological innovation”“ecological environment” and “coordinated development”, and the hot keywords are interrelated and nested. The research topics can be summarized from four levels, including economy, innovation, coordination, and green.

In order to reveal the main innovation subjects and technology leaders in the global industry, and provide guidance for China’s industrial policy formulation and enterprise technological innovation strategy, a seven-dimensional patent analysis framework was proposed to analyze the technological development trend of amorphous alloy industry based on the study of patent data. Through patent search and statistical data, the development trend of amorphous alloy patent applications, innovation regions, flow distribution, innovation subjects, innovation categories and innovation hotspots were identified. It is found that the number of patent applications for amorphous alloys has shown a downward trend in recent years, especially in Asia.

As China enters the middle stage of industrialization and modernization, both energy consumption and carbon emissions are growing, posing an increasingly serious challenge to sustainable development. The industrial sector is a major source of carbon emissions, and its structural optimization is crucial for reducing carbon emission intensity. Based on a sample of 30 provinces in China from 2005 to 2021, a dynamic panel threshold regression model was applied to treat provincial cooperation as a threshold value, and the mechanism of industrial structure optimization on carbon emission intensity was explored from two dimensions: rationalization and advancement of industrial structure. The results show that the rationalization and upgrading of the industrial structure have a significant negative impact on carbon emission intensity. However, the rationalization of industrial structure has a significant three-threshold effect on carbon emission intensity, and this negative effect shows a “V” type change trend on the whole. The upgrading of industrial structure has a single threshold effect on carbon emission intensity. The upgrading of the industrial structure will significantly promote the reduction of carbon emission intensity only when the provincial cooperation index is at least 2.013. The government should actively establish a cross-provincial cooperation mechanism to foster the coordinated development of inter-provincial industries and facilitate the extensive sharing of clean energy technologies, thereby promoting the transformation of the economy towards a green and low-carbon future.

The synergy of industry stakeholders is crucial to the high-quality development of prefabricated building, but there are many stakeholders with different interests and fields of specialization during the whole life span. Based on the industrial ecological perspective, the social network analysis method was adopted to study the relationship network from three aspects, including identifying the stakeholders, clarifying the relationship, and analyzing the network structure. The study shows that the decision-making, construction and demolition phases are high-density networks with close stakeholders synergy, the design phase has loose network relationships and the most unstable structure. The developer in the decision-making stage, the construction unit in the construction stage, the demolition unit in the demolition stage has the highest degree of centrality, dominating the synergy of the stakeholders. As a result, it is proposed to optimize the network structure to promote sustainable development.

The research results and trends of China’s recreational behavior in the CNKI(Chinese National Knowledge Infrastructure) database from 1994 to 2024 were analyzed by using CiteSpace. The results demonstrate that the number of articles published has undergone three distinct phases: the “budding period,” the “rapid growth period,” and the “fluctuating growth period.” The research results are grouped into three primary categories: recreational behavior and its influencing factors, utilization of recreational resources and protection and development, and the behavior of open space. The key topics in this field are recreational behavior, the elderly, open space, and urban parks. The research hotspots in this field are open space, leisure behavior, the elderly, open space, and urban parks. The research trends in this field are pocket parks, optimization strategies, landscape gardening, and parks and green spaces. In the future, it is suggested to deepen the theoretical system, improve the application of new technology and methods, and explore new perspectives of research.
