Wood science and technology

Overview

  • China has 195.45 million hectares of forests (289 million acres), 4.95% of the world’s forests, 5th position in the world.

  • Current forest coverage: 20.36% (18% in 2003).

  • The total standing stock volume is 17,913 million cubic meters.

  • Forestland ownership: owned by the State; 60% is managed by collective farms and 40% by the state.

  • Total number of employees in Forestry, Wood industry, and Pulp and paper industry: 12.9 million (2000 data).

  • U.S. is the major forest products export trade partner.

China’s Forests - River Valleys

  • 7 of the 10 largest river basins in China: Forest area – 70%; Stock volume – 60%

  • The area and stock volume of the forests in the drainage areas of the Heilongjiang River and the Yangtze River make up about 50% of the total.

China’s Forests - Forest Regions

  • Major regions:

    • Northeast Inner Mongolia

    • Southwest mountainous region

    • Southeast low mountain and hilly forest region

    • Northwest mountainous forest region

    • Tropical forest region

  • Forest area of the 5 major forest regions - More than 70% of the country's total.

  • Stock volume of these regions - Nearly 90% of China's total.

Major Forest Conservation Projects Natural Forest Protection Project (NFPP)

  • Completely stop harvesting in the upper reaches of the Yangtze River and the upper and middle reaches of the Yellow River.

  • Significantly decrease the amount of log production in the Northeast, Inner Mongolia forest regions.

  • Carefully protect natural forests in other areas by the local authorities.

  • The project targets to decrease the log production to 19.91 million cubic meters, and protect 94.3 million hectares of forests.

For example, a project in Qinling mountains.

Major Forest Conservation Projects

Grain for Green Project

  • Control 22.68 million hectares of area with soil erosion and water problems.

  • Fix 26.68 million hectares of dessertifation area.

  • Decrease 260 million tons of sediment which flushed into the Yangtze and Yellow Rivers.

Major Forest Conservation Projects

Wind and Sand Storm Control

This project is mainly to deal with the sandstorms that occur around Beijing area.

It targets to increase the forest and grass coverage rate from 6.7% to 21.4% by the end of 2010.

Wind and sand storm source control project in Inner Mongolia.

Major Forest Conservation Projects (Cont’d)

Three-North and Yangtze River Basin Shelter

Forest System Project - ”Green Great Wall”

  • The biggest shelter forest project in China, started in 1978 and will last until 2050.

  • Cover 42.4% of the total land area of China, including northeast, north central, and northwest, 13 provinces or 551 counties.

  • The plantation area will reach 35.62 million hectares, and forest coverage rate will be 14.95% in the three-north area by 2050.
