Examining industry output, productive berths, and GDP in China informs effective policy strategies for sustainable development, with a focus on key ports like Xiamen Port in the southeast region of china. Utilizing multiple regression analysis, this study explores the relationships among industry output, productive berths, and GDP, particularly focusing on Xiamen Port's significance in China's economic landscape. A negative correlation exists between primary industry output and GDP, emphasizing the need for sustainable industrial policies. Secondary industry also influences GDP negatively, albeit to a lesser extent. Increased productive berths positively impact GDP, highlighting infrastructure's role in economic growth. Balancing economic growth with sustainability requires targeted policies. Infrastructure development is crucial for economic performance. However, cautious interpretation is essential due to regression analysis limitations.

The need for deep integration of culture and tourism, aiming ultimately to establish a Chinese discourse and narrative system. This includes creating two windows and one position: transforming the tourism industry into a window for spiritual civilization and a platform to promote Chinese civilization and modernization achievements, serving as an important base for spreading scientific knowledge and advanced culture. In response to the national call, we are tasked with a new cultural mission to build the modern civilization of the Chinese nation. Around the national development strategy and key areas such as strategic emerging industries, the "Rural Revitalization Cultural and Art Planning" proposal has been approved as a national experts service grassroots demonstration team project. Initially targeting regions like Shandong, Guizhou, Jiangxi, and Shanghai across four cities and five districts and counties, the project focuses on research, guidance, and deep practice to transform cultural and tourism performances into unique cultural attractions for rural revitalization.

After entering the 21st century, with the continuous development of science and technology, people's demand for energy continues to grow. However, the fossil energy reserves accumulated by the earth for hundreds of millions of years are decreasing, which makes it difficult to meet the material and spiritual and cultural needs of human beings. And the global environmental problems are becoming more and more serious. Therefore, people must use brand-new, safe and sustainable clean energy to gradually replace the old burning fossil energy. Wind energy and light energy are clean and renewable energy, with almost unlimited reserves, which will not cause too much pollution to the environment. However, they are easily affected by the external environment, and their power output is unstable. It is necessary to combine them to achieve complementary functions. At the same time, combining them will control many objects and have multiple inputs and outputs, which is difficult to control by traditional control methods. The rapid development of modern intelligent control technology and electronic technology provides technical support for intelligent control. Based on the intelligent control research of new energy wind-solar hybrid charging and power consumption system, this study solves the problems of active power, voltage and frequency control in the current application process of new energy wind-solar hybrid, and formulates a set of practical control methods for new energy wind-solar hybrid charging and power consumption system through intelligent control research, thus improving the utilization efficiency of new energy wind-solar power generation. It can also make up for the domestic research gap and has certain technological innovation.

In promoting agricultural modernization, the Ningxia Hui Autonomous Region Agricultural Exploration and Design Institute should focus on technological innovation, optimizing industrial layout, strengthening resource management, and building an effective governance system. Through technological progress, the development of smart agriculture, as well as talent cultivation and interest linkage, Ningxia can achieve the goal of agricultural modernization, improve the efficiency of agricultural product supply, and enhance rural vitality.

Pinglu Canal is a newly-opened strategic channel for river-sea combined transport, and it is an important measure to build a China-ASEAN international channel. By connecting Xijiang "Golden Waterway" with Beibu Gulf Port, the problem of insufficient capacity of Changzhou Hub can be solved to some extent. Seize the great opportunity of Pinglu Canal construction, develop new quality productivity according to local conditions, promote the development of new industries, new models and new kinetic energy, and help the local modern water network construction and high-quality development of water economy.

Large thermal power plants use primary fan frequency converters to control the speed of the primary fan, which brings considerable economic benefits to the power plant. Frequency converter faults often occur during the operation of the frequency converter, causing the primary fan frequency conversion to cut the power frequency or trip, resulting in unstable operation of the thermal power unit or reduction in output. In order to ensure that the primary wind turbine can be safely shut down due to frequency conversion failure and can operate safely in parallel after the frequency converter is inspected, this article discusses this process.

Liquefied natural gas is a clean and efficient energy source. As a rising star in the global energy industry, LNG import and export is expanding, which mainly depends on two aspects. For energy consuming co-untries, importing LNG can achieve energy diversification, reduce energy costs, and ensure energy security. For LNG exporting countries, it is beneficial to the full development of natural gas energy, increase the foreign exchange income, and promote economic growth. It analysis the merits and drawbacks of every proposals from process simulation, process description, applicability, temperature parameters, liquefaction energy consumption, major equipment, investment etc. With increasing environmental protection pressure and environmental protection requirements become higher than before. LNG is conducive to improving the utilization efficiency of natural gas, which is in line with the country's strategy of replacing coal. The LNG market has broad prospects, high added value and good benefits. Although the price of LNG is higher than that of pipeline gas, it still has a advantage compared with oil.
