环境污染胁迫下生物的适应代价及其生存策略分析

Biological Adaptation Cost and Its Survival Strategies under Environmental Pollution

在污染环境中的生物面对“新环境”的压力,从短期来看,这种“新环境”是有害的,不利于生物生存繁衍;从长期来看,耐受性的生物将会成为新的广泛种,面对各种复杂环境都能生存,进而新环境是有利于其繁衍分布的,这就形成了环境污染胁迫下生物的适应代价以及生物作出的生存策略。本文从生物付出的生态代价、生理代价及进化代价三方面适应“新环境”着手,分析生物为了存活而调整生活史、形态学、解剖学及生理生化等,重塑新的生存策略。生物适应与生存策略均是生物最大限度地生存和繁殖的方式。

In the polluted environment,the organisms face the pressure of“new environment”.In the short term,this“new environment”is harmful and is not conducive to the survival and reproduction of the organism;in the long run,the tolerant organism will become new.A wide variety of species can survive in a variety of complex environments,and the new environment is conducive to its reproductive distribution,which forms the adaptation cost of organisms under environmental pollution stress and the survival strategies made by organisms.This paper starts with the ecological environment,physiological cost and evolution cost of biological treatment,and analyzes the biological life to adjust the life history,morphology,anatomy and physiology and biochemistry,and reshape the new survival strategy.Both biological adaptation and survival strategies are the maximum survival and reproduction of organisms.
