A variety of abiotic factors can affect the number of organisms in a population. Sometimes one or more factors,known as limiting factors,are more important in regulating population growth than other factors. This ecological principle is called the limiting factor principle:Too much or too little of any abiotic factor can limit or prevent growth of a population,even if all other factors are at or near the optimal range of tolerance. This principle describes one way in which population control-a scientific principle of sustainability(Figure 1-13,p.20 and back cover,and Concept1-6,p.19)-is achieved.

各種非生物因素可能會影響一些生物體的人口,有時候一些因素被稱為限制因素在調控人口增長方面比其他因素來的重要,這生態原則被稱為限制因素的原則:過多或過少的任何非生物因子會限制或阻止增長的人口,即使是在其他因素都達到或接近最優地情況,這一原則描述了人口控制,永續發展的科學原則(在圖1-13 P.20和概念1-6 P.19)實現了
