C. 我國人口地理界線是內(nèi)蒙古黑河——云南騰沖一線 D. 我國人口基數(shù)大,增長快

【答案】D

【解析】

A、根據(jù)2010年全國第六次人口普查結(jié)果,中國總?cè)丝跒?/span>13.7億,約占世界人口總數(shù)的1/5以上,是世界上人口最多的國家。故A不符合題意;B、C中國人口地區(qū)分布不均。一般來說,以黑河-騰沖線為界,東部地區(qū)人口多(稠密),西部地區(qū)人口少(稀疏).故B、C不符合題意;D、由于我國人口基數(shù)大,青少年的比重高,在今后一段較長的時期內(nèi),人口總量還將持續(xù)增長。因此,實行計劃生育,控制人口的數(shù)量,提高人口的質(zhì)量,是我國一項長期的基本國策,故選D。
