摘要
传统矿产储量计算模型基于欧式测量，应用于小比例尺海洋矿产储量计算时存在精度差的问题，论文通过对WGS1984投影、墨卡托投影、兰勃托投影以及阿尔伯斯投影等特性的研究，提出将矿产实体进行切片处理，计算切片间矿物实体的体积累加和的方法，实现了海洋小比例尺地图投影下储量的精确量测及体积计算，系统地论述了在不规则地球椭球体下如何实现海洋矿产储量计算，为我国海洋资源探测和军事战略方面提供基础服务。
To the small-scale map in ocean mine reserve field, the traditional measurement method computes the reserve with a relatively coarse precision. In order to improve that, a new method has been provided in this study, which uses AreEngine technology to finish the conversion be- tween different projections and measure the earth＇ s area as well as other information precisely. And then cut the mine reserve object into several pieces, so we can calculate the volume of the reserve by summing every piece. The different projections, such as WGS1984, Mercator, and Alhers, also have been discussed, which can provide a good service for the military strategy and exploration of ocean resources.
