The sixth national enumeration of forest resources (1999-2003) demonstrated that the total forest area was 175 million hectares, and the forest coverage rate was 18.21 percent. The total standing stock volume was 13.62 billion cubic meters, and the stock volume of the forest was 12.46 billion cubic meters.
Natural forests are concentrated in the northeast and the southwest, but scarce in the densely inhabited and economically developed eastern plains and the vast northwestern region.
However, the forests in China are rich in tree species, with the number of arbor species alone exceeding 2,800. Rare and peculiar species include ginkgo and metasequoia (dawn redwood). In order to conserve environment and meet the needs of economic construction, China has launched large-scale afforestation campaigns. The area of planted forests has reached 33.79 million hectares, accounting for 31.86 percent of the nation's total forest area, making China a country with the largest area of planted forests in the world.
Northeast China Forest Zone Located in the Greater and Lesser Hinggan
Mountains and the Changbai Mountains, it is the largest natural forest
area in China, with its forest coverage and timber reserves accounting
for over one third of the national totals. The area turns out half of
the national total timber output. Chief tree species include larch and
Korean pine.
Southwest China Forest Zone China's second largest natural forest
area, it consists of forests in the Hengduan Mountains, on the southern
slopes of the Himalayas and in the area at the U-turn of the Yarlung Zangbo
River. Its forest reserves make up one-third of the national total. Main
tree species include fir, red sandal and nanmu.
Southeast China Forest Zone Comprising mainly planted forests, it covers the vast hilly areas south of the Qinling-Huaihe line and east of the Yunnan-Guizhou Plateau. Economic tree species are mainly planted in the zone, such as tea shrubs, moso bamboo, masson pine and lacquer tree.
Shelter-forests In a bid to resist sandstorms and prevent soil erosion,
China has constructed many shelter-forests, such as the three-north (northeast,
north and northwest China) shelterbelt, shelter-forests along the middle
and upper reaches of the Yangtze River, coastal shelterbelt networks,
afforestation project in the Taihang Mountains and the plain afforestation
project. Of these, the three-north shelterbelt under construction, which
is regarded as "the world's greatest ecological project," will extend
more than 7,000 km and cover 260 million hectares, accounting for a quarter
of China's total land area. |
