Abstract:

The present paper deals with evolutionary principle and conservation strategies of biodiversity. Some unsatisfactory explanation of biodiversity in traditional evolutionary theroy was pointed. A new explanation according to the organic adaptive evolutionary theroy was discussed. The expression of biodiversity,
Bd=T[(Gc-m+MEc-(Nt+Ap+Hf)]dt,
(Bd—biodiversity; Gc—genetic material combinations; m—reduced value of genetic material conbinations for mutation; M—increased value of genetic material combinations; Ec—environmental element conbinations; Nt—natural thinning; Ap—artificial prune; Hf—hunted for food) was advanced first in this paper. Some principles of conservation strategies of biodiversity were given using its expression.
