Abstract:

Species diversity is closely related to forests. The major reason for the accelerated extinction of species is deforestation, especially in the tropics. We should attach great importance to reforestation and protection of habitats so as to regain and conserve species diversity. In this paper, we will discuss two methods of reforestation (natural recovery and artificial reconstruction) , and their effects on species diversity increment. We propose that artificial method can raise species diversity more effectively and rapidly than natural method. Meanwhile, based on the fact that high species diversity and ample biological resources exist in Dinghushan Biosphere Reserve, we suggest that more protected areas, even if they are not so big in size, should be established in China to conserve species diversity and protect more forest habitats.
