【2】A

【解析】

试题分析:

【1】环境人口容量受到资源因素、科学技术因素、对外开放程度、生活消费水平等因素的影响。而资源状况、科技发展水平及人口的生活消费水平是变化的,故不同的发展时期环境人口容量不会相同,且环境人口容量受外界因素的影响较大,则A、C错。环境人口容量与人们的生活消费水平呈反比关系,故B错。环境人口容量是指环境所能容纳的最大人口数,故D正确。

【2】人类的生存条件在很大程度上取决于资源状况,资源越丰富能供养的人口越多,故自然资源的总量决定着环境人口容量的大小。科技水平、对外开发程度、生活消费水平是通过影响资源的开发和消耗而影响环境人口容量的大小,故资源是制约环境人口容量的首要因素,A正确。
