  3. 3. 1. Bamboo Resource and Industry in China
  4. 4.  Bamboo is one of the fastest growing plants in the world , which could be used as industrial material in 3-5 years old.  China has rich bamboo resource , more than 30 genera and 500 species. Bamboo forest area was 3.2 million hectares in 1981, while 6.01 million hectares in 2013. Planting bamboo forest area of six provinces (Zhejiang, Guangdong, Sichuan, Guangxin, Fujian and Anhui) accounts for 77%. 1.Bamboo resource and bamboo forest area
  5. 5. 2. Bamboo industry and bamboo products  More than one hundred series including ten thousand kinds of bamboo products , used in various fields including Bamboo-based engineered materials, bamboo furniture, bamboo floorings, bamboo pulp and paper, bamboo shoots, bamboo crafts, etc.  Bamboo industry output value reached 167.1 billion RMB ($28 billion). Import and export trade volume reached $2 billion or above.
