生态压力 危及生物个体或种群的生长及生殖的外界干扰（如寒冷、干旱或饥饿等）及其所产生的生理效应；危及生态系统稳定性的外界干扰（如人口增长、资源短缺或环境污染等）及其所产生的生态效应。生态压力的研究是目前生理生态学、系统生态学和人类生态学的重要内容。 这里的"压力"一词有几种基本含义：或指一种作用,一种生理的或生态的作用过程;或指引起这个过程的原因,如寒冷、污染等生态因子本身;或二者兼指；也有人用它指作用过程所产生的后果，即功能受干扰的状态。英语中stress原有重负之意，在物理学上指应力。该词广泛应用于生理学和心理学，曾被译为"应激"、"胁强"、"逆境"等。在生理学上，一般指强大而持续的刺激影响机体的整体功能，危及内环境的稳定状态（持续饥饿、严重脱水等）。后来此概念引用于生态系统和社会系统。 生物个体对外界生态压力的耐受力随物种而异。个体在不同发育阶段，耐受力也不同。成体耐受力一般比幼体高，因为成体的内环境稳定机制已成熟。生态系统也存在一定的稳定调节机制。例如，当生态系统受污染较轻时，在包括生物降解在内的各种机制作用下，系统功能基本不受影响；但当外界生态压力超过系统调节能力时，便可能强烈破坏系统的生态平衡，使植被遭受破坏，食物链上各级生物受损伤甚至死亡，由此导致生态系统的结构紊乱，功能失调，生物量下降和生物生产力衰退等严重后果。 物理学中与应力一词相联系的还有应变一词，指物体形状尺寸受外因（如受力、温度变化）或内在缺陷影响而发生的相对改变值（与原有形状尺寸的比值）。把它引伸到生物范畴，即指系统结构与功能在强大干扰下偏离正常状态的程度，并译为逆变(strain)。并可用两者的比值来表明生态系统对这种干扰的耐受性： 耐受性＝生态压力／生态逆变
