| 摘 要： | 地缘环境是由地理位置相互联系并产生关系的环境.文中提出将地缘环境指标分为本底、关联及位势3大类,其中本底指标又被分为社会经济、政治军事、战略资源和生态环境4类,各类又被细分为4个子类,各指标之间可以通过加权叠加方法进行综合生成指标体系.标准差反映数据与其平均值之间的离散程度.文中以标准差法为划分方法,以地缘环境指标体系及其加权叠加为划分依据,对我国周边地缘环境中的敏感地区之一——南亚进行了地缘环境单元划分实验.实验结果表明标准差方法在地缘环境单元划分中表现有效且准确.

| Abstract: | Geographical environment is arising from the geographical position linkages.The geographical environment indicators are deeply studied and summed up here,and then divided into the background,the associated and the potential.The background indicators are divided into four categories,such as the socioeconomic,the political and military,the strategic resources and the ecological environment,which can be divided into more sub-indexes.While the sub-indexes can be integrated to comprehensive indicator system by weighted stacking method.The standard deviation classification method reflects on how the data varies from the mean.The experiment of Chinese surrounding geographical environment unit division has been done based on the standard deviation method,the geographical environment indicator system and the weighted stacking method,taking South Asia as an example.The result indicates that standard deviation method is of high accuracy and efficiency on the geographical environment unit division. |
