On April 27, 2022, Sichuan sound environment Group Co., Ltd. and Sichuan Tongguang Investment Consulting Co., Ltd. held a grand signing ceremony for the construction project of new energy, new materials and new agriculture pilot zone of desert economy in Mangya City, Qinghai Province in sound environment. Mr. Liu Xianqing, chairman of sound environment, and Mr. Shang Luguang, general manager of Tongguang investment attended the meeting and signed the contract. At the same time, the sound environment also specially hired Mr. Shang Luguang as the chief planner of the company.

Sound environment: after nearly 20 years of efforts, we have gathered the technologies * of desertification control, soil improvement and sewage treatment, and initially have the practical ability of desertification control, soil improvement and agricultural industrialization operation. Tongguang investment has experience in project planning, planning and application. In particular, President Shang has a unique perspective and strategic vision in policy research, project analysis and planning. In terms of desertification control, after several rounds of exchanges and consultations, the two sides finally reached cooperation.

It is one of the most serious deserts in the world. The area of desertified land is 2.64 million km2, accounting for 27.5% of the total land area. Among them, the desert is particularly serious, with an area of 809000 km2, and it is still expanding. On average, about 610km2 of deserts are activated every year, of which 310km2 is reduced to sand. Desertification has caused ecosystem imbalance and the area of arable land has been shrinking, which has a serious impact on industrial and agricultural production and people's lives* The deserts and desertified lands in the arid areas of Northwest China have become one of the main sources of sandstorms in China and even the Asia Pacific region, causing huge losses to the society and economy of China. It is urgent to control the desert* After long-term desert control, we have acquired certain desertification control technologies, formed effective management institutions, teaching and scientific research systems, formulated a series of policies and regulations, and reached the leading level in the field of desertification control. However, what is thought-provoking is that although more and more investment is made and the control efforts are increased year by year, the rate of desertification expansion is getting faster and faster, and there is a trend of further aggravation.

This joint venture of sound environment and Tongguang investment to jointly commit to the development of environmental protection is an important milestone in the development of both companies. Both sides expressed that in the future cooperation process, they will sincerely unite, complement each other's advantages, and strive to make great breakthroughs in desert governance, soil improvement and agriculture.

Mr. Yuan Denghui, technical director of sound environment, and other senior executives attended the signing ceremony.
