中文摘要：

结合北京城市总体规划（2004～2020）对各新城的功能定位，利用年龄移算法、考虑未来经济增长速度及劳动力需求等，对北京城市规划重点建设的新城之一——昌平的人口规模进行了预测研究。结果表明，自然增长情况下，昌平人口呈现下降趋势，由2000年的51．5万下降到2020年的48．9万；但随着北京城市中心区人口和产业的转移，昌平在疏解中心区职能方面将发挥巨大作用，其人口总量必将大幅度增加，机械增长是未来昌平区人口总量增长的主要原因。预测分析，2000～2020年，昌平区机械增长人口总量预计在52～63万人，2020年，昌平区人13超过100万。在人口大规模增长的情况下，需要采取一定措施，满足新增人口用水用地的需求，实现人口的顺利转移，保证其对昌平新城对北京中心城区职能的分担。
