冀中平原古森林研究初报

A Preliminary Report about the Ancient Forests on the Central Hebei Plain

五十年代末以来,冀中平原1300平方公里范围内,发现埋有大量古林木.枯枝腐叶层的存在,埋藏木的密度,以及麋鹿头角化石的发现,证明古林木乃是古森林的遗迹.从孢粉分析和^(14)C测定的结果和这一地区古河道分布的情况看,古森林存在于距今7500—2500年之间.

A lot of ancient forest trees have been found on the central Hebei plain (about 1300 squre km) since the end of 1950s. The trees are proved to be the trace of ancient forests through discovering the tress with fixed densities and the layers of their dead branches and leaves, and fossils of heads and horns of David's deers (a kind of ancient animal in North China, wildlife of which disappeared now). By mean of pollen analysis, 14C determination, and inverstigation on the distribution of anciant river courses in the area the ancient forest was considered to exist in 7500 to 2500 years ago.
