| China lacks forests.
Totaling 158.94 million hectares, forests cover 16.55 percent of China's
total land area, far less than the world's average level of 30.8 percent.
Natural forests are concentrated in the northeast and the southwest, but
scarcely distributed in the eastern plain 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). The area of planted forests has reached
33.79 million hectares, accounting for 31.86 percent of the country's total
forest area, making China a country with the largest artificial afforested
area in the world.
The Northeast China Forest Zone:Located
in the Greater and Lesser Hinggan Mountains and the Changbai Mountain,
it is the largest natural forest area in China, with its forest coverage
and timber reserves accounting for over one-third of the national total.
As China's largest lumbering base, the area turns out half of the national
total timber output. Chief tree species include larch and Korean pine.
The Southwest China Forest Zone:The second
largest, 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 red sandal and nanmu.
The Southeast China Forest Zone:Comprising
mainly planted forests in China, it covers the vast hilly areas south
of the Qinling Mountains and Huaihe River and east of the Yunnan-Guizhou
Plateau. Planted forests mainly contain economic tree species, such as
tea plants, 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 on the Taihang Mountains
and the plain afforestation project. Of these, the three-north shelterbelt
has been regarded as "the world's greatest ecological project". |
