C. 沿漠河——腾冲一线,东南部人口稠密,西北部人口稀疏

D. 我国约占世界人口1/5,是世界上人口最多的国家

【答案】C

【解析】

根据中华人民共和国成立后,由于人民生活水平的提高和医疗卫生条件的改善,人口死亡率大幅度下降,中国人口快速增长,成为世界上人口最多的国家,进行分析解答。

新中国成立前,我国人口增长较慢,新中国成立后,人口增长迅速,故A不符合题意;

我国人口基数大,青少年的比重高,在今后一段较长的时期内,人口总量还将持续增长。口与经济、社会、资源、环境的矛盾依然会十分突出。因此,实行计划生育,控制人口的数量,提高人口的质量,是我国一项长期的基本国策。故B不符合题意;

中国人口地区分布不均。一般来说,以黑龙江省的黑河云南省的腾冲线为界,东南部地区人口多(稠密),西北部地区人口少(稀疏),故C符合题意;

根据2010年全国第六次人口普查结果,中国总人口为13.7亿,约占世界人口总数的1/5,是世界上人口最多的国家。故D不符合题意。

故选:C
