| 摘 要： | 从城市生态系统承载力的空间差异性出发，集成GIS空间评价技术和系统动力学（SD）模型，确定城市区域适度总人口规模和各分区人口数量，提出人口分区定量配置新思路和技术集成方法，并将该方法应用于300万人口城市--常州.结果表明： 通过构建常州市区人口、经济、土地与环境的系统动力学模型和多情景模拟分析，在同时满足城市经济发展与环境保护需求下，常州市区远景（2050年）总人口约400万；基于城市承载力空间差异评价进行常州市区总人口的空间配置，将形成240万人的主城及5个15～40万人新城的空间格局，研究结果可为国土开发管理中人口与经济的空间分配提供科学依据.

| Abstract: | Global warming makes the resource exploitation and utilization of Polar region be possible. However, due to the special status of Polar region in international laws, there are many debates in international communities about the relevant rights and interests of Polar region. These debates mainly manifested in two aspects, i.e., legal conflicts between international treaties, and legal conflicts between international and domestic laws. China has a great development space in the marine affairs of Polar region. Accordingly, the researches on the Polar region legal issues can provide corresponding legal bases and countermeasures to China in its dealing with the relevant international marine affairs in the future. |
