生：環(huán)境承載力是指環(huán)境能持續(xù)供養(yǎng)的人口數(shù)量。師：對了。但是有同學仍然會感到這是一個很抽象的概念。下面我們具體來了解什么是環(huán)境承載力。我們可以從兩個部分去理解：一、環(huán)境，它主要是指環(huán)境的單個要素（如：土地、水、氣候、植被等。）及其組合方式。二、是承載力，它指在特定的條件下，具體某事物能承受的某種活動的最大值。那環(huán)境承載力的科學定義是怎樣表達的呢？生：環(huán)境承載力是指某一時期，某種狀態(tài)條件下，某地區(qū)環(huán)境所能承受的人類活動作用的閾值。師：很對。 我們可以用一個生動的例子來說明。一只木桶里面的水的多少在底面積固定不變的情況下是由哪塊木板來決定？生：最短的那塊。師：確實如此。這就是我們平常所講的 “木桶效應”。那影響環(huán)境承載力的大小也是由環(huán)境個要素里面最緊缺的那個要素來決定的。下面我們用一個例子來印證一下。
