| Abstract: | The vegetation of the Taihang Mountains was dominated by grass with less than 10% forested area during the last pleniglacial.
During the period of 17 000 – 10 000 a B. P. the forested area reached to 20% – 30%, and reached to 20% – 40% during the Early
Holocene in the period of 10 000 – 8 000 a B. P. followed by the temperature increasing rapidly. But the northern part had
more forested area than that of the southern part. During the period of 8000 – 5000 a B. P. forests developed further to 50%
or more. It was the highest period of the forest cover degree. After then, the forests began to be destroyed first in the
southern part of the Taihang Mountains by people. Since 2500 a B. P. the forests were destroyed deadly. The forest cover decreased
to less than 5% before 1949. Since 1949, although the government hold the policy of close hillsides to facilitate afforestation,
the forest cover of Taihang Mountains could not exceed 11.6%. So afforestation is an important work to keep economic and ecological
sustainable development. |
