【题目】中国科学院发表的《中国土地生产能力及人口承载力研究报告》报告中指出,我国最适宜的人口数量是7亿左右,最多人口数量应该控制在16亿左右。据此,完成下列各题。

1报告中所指的“7亿左右”人口数值,其含义是指我国的 ( )

A. 人口合理容量

B. 环境所能供养的人口极限

C. 环境承载力

C. 自然资源状况 D. 科技水平

【答案】

1A

2A

3C

【解析】

1因7亿左右的人口是我国最适宜的人口数量,所以是指人口的合理容量;而环境承载力、环境所能供养的人口极限、维持最低生活消费水平的人口数量等,都是我国能够供养的最大人口数量。故选C。

2加大资源开发力度,会导致资源破坏,甚至枯竭,降低环境承载力;持续扩大耕地面积,会破坏生态环境,降低环境承载力;不断增大城市用地面积,使土地资源减少,降低环境承载力;而控制人口数量,提高人口素质,会减少资源的消耗,保护生态环境,提高环境的承载能力。故选D。

3影响环境人口容量的因素有:资源的丰富程度、科技水平、经济发达程度、对外开放程度、人口受教育水平及消费水平等。其中资源的丰富程度和科技水平是制约环境人口容量的重要因素,而资源状况则是影响人口承载力大小的首要因素。
