生态系统的进化

Evolvement of Ecosystem

地球环境的不可逆变和生物物种的进化,是驱动生态系统进化的基本因素。而自然界中的所有生物物种都处于生态系统之中,生态系统内的物种进化是在生态关系中实现的,在自然界中不存在孤立的物种进化。本文从生态系统内物种的竞争、协同进化与共存等方面谈生态系统的进化。

The main factors,which drive ecosystem to evolve,include the earth environment's non-converse evolvement and biology species' evolvement.All kinds of biology species in nature exist in ecosystem.The species realize their evolvements in ecology relations.There is no specie that could evolve independently.This article discussed biology species' evolvement from the aspect of their comptition in ecosystem and their co - operation evolvement and their coexistence.
