1, the need of national economic construction. Since the reform and opening up, because the country needs a lot of wood for construction, for a period of time, the wood production of state-owned forestry bureaus and state-owned forest farms in China pursued exceeding their tasks, resulting in a large number of over-exploitation.
2. Social supply demand. In the construction of national economy, the social demand is increasing, especially the improvement of people's living standards, and the consumption of wood products is increasing, such as decorative materials, solid wood furniture, paper products and so on. This makes it a common practice to cut down a lot of wood.
3. The state-owned forestry economy is in jeopardy. State-owned forest farms once accumulated wealth for national economic construction and consumed a lot of forest resources. After the reform and opening up into the market economy, most of the forest resources in state-owned forest farms have dried up, and some have reached the point where there is no forest to cut. However, in order to maintain workers' life and social stability, forced logging is necessary, so trees are becoming thinner and thinner, and forests are becoming thinner and thinner.
4. Driven by economic interests. Forest resources are national or collective, and they are long-term accumulated wealth. Some people, driven by interests, wantonly cut down, illegally cut down and smuggle and transport timber. In addition, the illegal cost is low, and deforestation is repeatedly prohibited.
5, the role of cadres' political achievements. In recent years, in order to speed up urban construction and beautify the environment, some cities have taken big trees into the city, dug up precious tree species in the forest and sold them. The forest is full of wounds, pits and ditches, and the soil erosion is serious, which makes the forest unable to recover.
