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, B d=∫ T O[(G c-m+M)·E c-(N t+A p+H f)]dt,(B d—biodiversity; G c—genetic material combinations; m—reduced value of genetic material conbinations for mutation; M—increased value of genetic material combinations; E c—environmental element conbinations; N t—natural thinning; A p—artificial prune; H f—hunted for food) was advanced first in this paper. Some principles of conservation strategies of biodiversity were given using its expression.
