replacement level
更替水平；替代水准
- This is known as the replacement level.
这就是人口更替水平。 - In the early 1990s, China’s fertility rate fell below what demographers call the replacement level, or the number of births needed for one generation to replace itself.
在90年代初期，中国的生育率下降到替换水平（人口统计学家称替换上一代人数所需要的出生人数为替换水平）以下。 - Yet even if Rwanda's fertility rate falls below replacement level, as it's projected to do by 2050, its population will still triple beyond what it was before the 1994 genocide.
然而，即使卢旺达的生育率低于了置换率的水平，根据其到2050年的人口发展计划，该国人口依然会达到1994年种族灭绝之前人口数量的3倍以上。
