【摘要】 由温室效应引起的全球性变暖越来越受到人们的重视。全球变暖对物种的影响是一个复杂和难以预测的过程,它会加速物种灭绝的过程。本文综合评述了由温室效应引起的全球性变暖对物种生存与灭绝的影响。全球变暖对物种生存的影响包括直接作用和间接作用。直接作用包括即时影响和延迟影响。间接作用包括食物影响;饮水影响;栖息地影响;环境的消失和挤出影响;捕食者,竟争者,寄生者,疾病平衡影响;共生者影响等。间接作用导致的物种灭绝可能比直接作用更严重。另外,本文论述了级联作用对物种灭亡的影响。最后,本文强调了应加强对人类活动引起的全球变暖的研究。更多还原

【Abstract】 The issue of global climatic warming caused by greenhouse effect has received wide attention throughout the world.The climatic warming influences species in a complicated and unpredicted way,and increases the speed of species extinction.The impact of climatic warming on species was comprehensively reviewed in this paper.The climatic warming influences species with direct effect, including immediate effect and delaying effect,and indirect effect,including food,water, habitat,environment pop - off and squeeze - out,the balance among prey,competitor,parasite and disease and symbiont.The indirect effect probably causes species extinction more seriously than direct effect.In addition,the impact of the chain reaction effect on species extinction was reviewed.At last,this paper suggests that the study on the impact of human activities on climatic warming should be stressed.更多还原
