Research and Practice of Green Maintenance Concept of Highway

2024-10-09T09:10:37+08:00

Abstract: The concept of green transportation has evolved and has become an important guide for modern transportation development. However, in China’s highway maintenance management, there are several significant problems, including relatively serious pollution of the environment, a large amount of waste of maintenance materials, poor recycling rate of waste materials, and relatively lagging construction technology. In response to these problems, this study discusses in depth the practical techniques of highway pavement and roadbed maintenance and puts forward specifc suggestions based on the concept of green maintenance. Through systematic analysis and practical verification, these measures show remarkable effectiveness in improving the quality of highway maintenance and promoting the development of green transportation.

Application Research of Geographic Information Systems in Forest Resource Survey and Planning

2024-10-09T09:10:36+08:00

Abstract: With technological advancement, Geographic Information Systems (GIS) have become a core tool in forest resource management. GIS integrates computer science, geography, and remote sensing technologies, enabling comprehensive exploration, precise management, and scientific planning of forest resources. This paper delves into the diverse applications of GIS in forest resource survey and planning, demonstrating its crucial role in enhancing management effciency and promoting sustainable development. Through GIS, we gain deeper insights into, protect, and manage forest resources more effectively, thereby making positive contributions to the ecological balance of the Earth and long-term human well-being.

Analysing Computer System Security and Computer Network Security

2024-10-09T09:10:35+08:00

Abstract: Computer system security and computer network security are the key areas to guarantee the security of data and information assets in the era of information technology. Computer system security focuses on protecting hardware, software and data from internal and external threats to ensure stable and reliable operation of the system. Computer network security, on the other hand, focuses on the protection of data transmission and storage security in the network, and effectively defends against network attacks and data leakage by means of access control, data encryption, network isolation and other means. The two are interdependent, and together they build a secure and trustworthy computing environment.
