摘要：

本文论述了传统进化论学说对生物多样性解释的不足,探讨用生物适化学说解释生物多样性的形成,提出生物多样性产生的表达式：
Bd=∫TＯ［(Gc-m+M)·Ec-(Nt+Ap+Hf)］dt,
并以此说明制订保育它们的原则对策。

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=∫TＯ［(Gc-m+M)·Ec-(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.
