Xu Xinwen, researcher at Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences, delivered a speech at the opening of the conference. In his speech, he emphasized: “The prominent contradiction between power station construction and the fragile ecological environment is becoming increasingly prominent. Therefore, how to integrate the development of photovoltaic power stations and desert ecological industries is one of the important issues that must be solved in the future development of desert photovoltaics. I hope that new energy companies will continue to strengthen cooperation and innovation. Give full play to the technical advantages of the institute in the field of desertification textiles and contribute to the integrated development of eco-friendly photovoltaic power stations and desert photovoltaic ecological industries!”
Fan Jinglong, Professor Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences
Fan Jinglong, senior engineer of the Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, delivered a keynote speech entitled “Thoughts and Actions on the Integrated Development of Photovoltaics and Sand Control in Xinjiang, China”. He pointed out that the integration of China’s photovoltaic power generation construction and desertification prevention and control is developing rapidly, and China has great potential in the development of solar power generation. In 2024, Xinjiang’s new energy installed capacity will be about 20 million kilowatts, ranking first in China at the same time. However, due to the influence of strong wind and sand in Xinjiang, local photovoltaic power stations face challenges. To meet the challenge, China plans to build an 800-kilometer-long solar “Great Wall” with an installed capacity of 100 million kilowatts around the Taklimakan Desert in Xinjiang to prevent desertification in Xinjiang. ”

Subsequently, Wang Fuzhou, Chairman and Chief Engineer of R&D of Zhengzhou Zheng Sai Shield Co., Ltd, delivered a speech entitled “New Technology of Redundant Desertification Control”.
Wang Fuzhou, Chairman and Chief Engineer of R&D of Zhengzhou Zheng Sai Shield Co., Ltd.
Wang Fuzhou said that traditional desert planting practices have the disadvantages of large water consumption, high maintenance costs, limited ecological adaptability, insignificant soil improvement effects, and limited scale and speed. In order to cope with the huge challenges of desertification, Zhengsai Group has developed a new desertification control and improvement technology, namely deep water storage permeability reduction gas impermeability technology. The technology can effectively reduce water penetration by setting up an impermeable “isolation layer” at a certain depth in the desert to store water and reduce gas permeability, so that water can be retained in the roots of plants for a long time to meet the needs of plant growth.
Guests discuss the relationship between photovoltaics and the ecological environment
In the subsequent dialogue session, Fan Jinglong, senior engineer of the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences, Ms. Hussein Kasim, negotiator of Ghana’s Climate Empowerment Action under the United Nations Framework Convention on Climate Change, and Dr. Jin Zhe of the School of Social Sciences of Tsinghua University participated in the dialogue discussion, and Dr. Zhang Huiwen of the School of Social Sciences of Tsinghua University served as the moderator of this session.
The guests discussed topics such as the impact of solar power plants on the environment, the importance of their site selection, and how environmental factors affect the reliability of power plants. The guests also analyzed the role of the government in promoting such projects and how photovoltaic panels can promote the recovery and development of ecosystems. Finally, the participants introduced the cooperation between Tsinghua University and the UN The RAP project, a CCD cooperation project, aims to promote the restoration of ecosystems through renewable energy.
The participants ended the meeting with a feeling of reluctance and a desire to leave. They had a deeper understanding of how the progress of photovoltaic technology introduced by different guests at the meeting complements the changes and development of the ecological environment and how to protect and improve the environment while promoting sustainable development.
They all agreed that the development of photovoltaic technology, as an important part of clean energy, not only helps to reduce greenhouse gas emissions, but also promotes the restoration of ecosystems and the protection of biodiversity. At the end of the meeting, the participants looked forward to more similar communication opportunities in the future to jointly promote the deep integration of photovoltaic technology and ecological and environmental protection.
