摘要
生境片断化是协迫生物多样性的重要因素之一。人类活动导致生境丧失 ,是生境片断化的主要原因 ,人工障碍物隔离生境也是生境片断化的重要因素。生境片断化限制物种流动性 ,造成边际效应 ,使生物多样性严重丧失。我们应保护原生生境 ,改善生态环境 。
Habitat fragmentation is one of the important facts of coercion on the biology diversity.The main reason for habitat fragmentation is that humen activities cause the loss of habitat.Another importatant fact of habitat fragmentation is that habitats have been kept apart by artificial obstacle.The habitat fragmentation limits species mobility,and produces the edge effects,so that it results in the servers loss of biology diversity.We have to protect the primal habitat,and improve ecological environment,to reduce the effects of humen activities on the biology diversity to the minimum.
