摘要
为解决海洋社会经济数据难以获取的问题,促进海洋空间评价的科学化和标准化,文章提出"海上虚拟人口"假说,并对其应用进行探索。研究结果表明:"海上虚拟人口"不是海上实际常住人口,而是对陆上人口数据进行插值后所形成的虚拟人口分布;某一海域的虚拟人口一般按照该海域与海岸线的距离进行插值,距海岸线近的数量多,距海岸线远的数量少;"海上虚拟人口"是海洋社会经济数据的载体之一,其数量可间接反映海洋开发利用水平和海洋社会经济状况;应用步骤包括确定海岸线形状、划分网格单元、修正原始数据和插值计算4个部分。目前"海上虚拟人口"假说及其应用仍处于探索阶段,需在实践中不断检验和完善。
In order to solve the difficulty to access marine socio-economic data and promote the scientific and standardized evaluation of marine space,this paper put forward the hypothesis of “virtual maritime population” and explored its application.The research held that:(i)“virtual population at sea” is not the actual permanent population at sea,but the virtual population distribution formed by interpolation of land population data;(ii)the virtual population of a certain sea area is generally interpolated according to the distance between the sea area and the coastline,the number close to the coastline is large,the number far from the coastline is small;(iii)“virtual population on the sea” is one of the carriers of marine socio-economic data,the number of which can indirectly reflect the level of marine development and utilization and the conditions of marine socio-economy;(iv)application steps include four parts: determining the shape of the coastline,dividing the grid cells,correcting the original data and interpolation calculation.At present,the hypothesis of “virtual population on the sea” and its application are still in the exploratory period,which needs to be constantly tested and improved in practice.
