| 摘 要： | 近年来，不断有位于河口三角洲区域的县区升级为国家级新区，科学地估算这些县区的宜居人口容量是新区规划的前提。文章通过选取河口区人居自然环境主导因子、提取人口承载区和参考同类区域平均人口密度和相关国家标准等环节，构建了一种基于人居环境适宜性的河口三角洲地区人口承载力的估算方法，并估算了广州原南沙区宜居人口容量。结果显示：原南沙区宜居人口容量为87万人，宜居人口密度为2 776人/km2，其中，南沙街23万人，黄阁镇21万人，万顷沙镇为19万人，横沥镇为13万人，珠江街为11万人。考虑到地基和经济发展差异，南沙区宜居人口密度与上海浦东新区、天津滨海新区之间和美国首都华盛顿特区的人口密度有较好的可比性。文章所用方法突出了水文与地质条件的约束作用，可用于估算河口三角洲地区人口容量。

| Abstract: | In recent years, more and more counties and districts in estuarine delta areas in China have been upgraded to national-level new districts. Scientifically estimating the population capacity of those districts plays a fundamental role in the planning of new districts. However, there is a lack of estimation method specific to the livable population capacity of estuarine delta areas in existing study. This study selects the dominant natural environmental factors for human settlements and extracts the population bearing areas referring to population densities of similar areas and relevant national standards to set up an estimation method to evaluate the population capacity in estuarine delta areas based on the suitability of human settlement environment. This method has been applied to estimation of the livable population capacity of the original Nansha District in Guangzhou. The research shows that the livable population capacity of Nansha District is 870 000 persons and the livable population density is 2 776 persons per square kilometer. The results of livable population capacity at township level in Nansha District are listed below: Nansha Subdistrict 230 000 persons, Huangge Town 210 000 persons, Wanqingsha Town 190 000 persons, Hengli Town 130 000 persons, Zhujiang Subdistrict 110 000 persons. As considering the actual discrepancy of the subgrade bearing capacity and the stage of socio-economic development, the livable population density of Nansha District is very comparable to that of Pudong New District in Shanghai, Binhai New District in Tianjin and Washington DC in the US. This estimation method highlights the restriction of hydrogeological conditions and can be used to estimate the livable population capacity of estuarine delta areas. |
