China's wood-based panel industry has developed rapidly, and its total output ranks first in the world, while plywood accounts for more than 50% of the total output of wood-based panels. The production areas of plywood are mainly concentrated in Jiangsu, Zhejiang, Hebei, Guangdong, Shanghai, Fujian and other economically developed and natural Provinces that are not rich in forest resources, since the 1990s, China has gradually developed into the world's largest producer of plywood. According to statistics from the State Forestry and Grassland Administration, the national plywood production in 2018 was 178.98 million m ³ . At present, the number of large-scale plywood production enterprises in China has increased, with an average production scale of 5000-7000 m ³ , and the number of registered plywood enterprises in the country exceeds 10,000. Resources are becoming more and more scarce. At present, these natural forest tree species are rarely used in plywood production. With the cultivation of plantations such as poplar and eucalyptus, fast-growing small-diameter woods such as poplar and eucalyptus have gradually become the main raw materials for the production of plywood.
