【摘要】 在"复合面积重心法"计算国土几何、生态、水资源、经济中(重)心的基础上,利用2008年面板数据分别确定了我国的陆地、全版图几何中(重)心及我国的人口、经济、生态、水资源和粮食中(重)心。比较了各重心与北京之间的生态距离,结果表明北京偏离各指标重心620～1487km。对定都北京62年后逐步显现的生态限制因子如水、大气及地形、地震等因子的限制作用进行了定性定量分析。研究"迁都"最佳位置(备选)的水源区域、核战争威胁的安全区域、最佳物产分布区域、最佳人文地理环境。对"迁都"的国家层面之损失和收益、物质成本和机会成本、迁都后的北京的发展、"迁与不迁"的抉择进行了限制生态因子方法、生态经济成本损益综合评估方法和生产力布局时空分析方法的研究。更多还原

【Abstract】 The barycenter calculated by composite proportion is parameterized according to the data of statistical yearbooks to calculate and interpret the geometry barycenter of land and entirely territory,as well as the barycenter of population,economy,ecology,water resource,and commissariat.By comparing the distance between the barycenters and Beijing,we find that the deviation is about 620 to 1487 km,which is not good for region administration.Besides,we analyze Beijing’s problem within the confines of the factors such as water,gas,landform,geology and earthquake after establishing capital in Beijing 61 years later.We discuss the area of the fullest water, the martial security area under threat of nuclear warfare,the area of the most products,and the area of the best anthropogeography in the best location for establishing a new capital.Finally,we evaluate the loss and benefit,physical cost and opportunity cost,development of Beijing after its moving to a new place,and choice of moving or not using different evaluation methods..更多还原
