As an important basic industry of China's national economy, the wood industry is an important support for improving living conditions, managing the ecological environment and developing the circular economy. It must firmly establish and implement innovation, coordination, green, open Shared new development ideas. Wood functional improvement Through advanced wood protection and treatment technology, it can improve the low density, perishability, variability and other natural defects of plantation wood, improve the physical and mechanical properties of wood, effectively extend the service life of wood, expand the application field of wood, and increase the value of wood, which is an important way to promote the innovative development and high-quality development of wood industry. It is hoped that this event can continue to play a leading role in the industry, promote the transformation and upgrading of the wood protection industry, and make greater contributions to the green development of China's wood industry.

Liu Nengwen, Director of the Wood Conservation and Development Center, President of the China Wood and Wood Products Circulation Association, and Honorary President of the China Wood Protection Industry Association, delivered a speech, expressing warm welcome and heartfelt thanks to everyone on behalf of the Wood Conservation and Development Center for coming to the conference! He said that China has become the largest wood and wood products processing country, trading country and consumer country in the world. At present, the annual output value of the industry is 2.2 trillion yuan, the total import and export trade is 88.86 billion dollars, the annual trade volume of commodity timber is 200 million cubic meters, and the timber consumption is nearly 600 million cubic meters. However, China is short of timber resources, and the contradiction between supply and demand of timber is more prominent. Through functional improvement, timber can effectively overcome its own defects, further expand the application field of plantation timber, and play a positive role in easing the contradiction between supply and demand of timber in China. It is believed that this forum will further build an international level exchange platform for wood modification industry, university and research and promote the development of wood modification industry by carrying out technical exchanges and cooperation, transformation of scientific and technological achievements, etc.
