| 摘 要： | 地质大调查以来区域重力调查取得了重要进展,1:100万区域重力调查基本实现了全国陆域的全覆盖,1:20万区域重力调查稳步推进,取得一批地质成果.区域重力调查技术进步突出:普遍使用各类高精度重力仪和GPS定位系统;区域重力数据库信息系统和几种二三维正反演软件得到推广;制订了新区域重力调查规范.为适应新形势的需要,区域重力调查要加快1:20万区域重力调查的工作进度,并合理部署调查和综合研究工作;每个图幅的具体调查任务和设计要有针对性;要改进地改和GPS高程改正方法,提高地改精度;要提高区域重力调查成果的解释水平,改进报告编写.

| Abstract: | Lots of important advances have been made since the performance of the general geological survey: 1:1000000 regional gravity survey has on the whole covered the whole continent of China;quite a few geological achievements have been obtained,with the major achievements being encouraging;technological progress in regional gravity survey is prominent,and various high-precision gravimeters and GPS systems have been extensively applied;the regional gravity database information system and several two-and three-dimensional forward and inversion softwares have been popularized;the new regional gravity survey standard has been formulated.To adapt the work to the new situation,we should speed up 1:200000 regional gravity survey and arrange the investigation and research work in a more rational way.The investigation task and design for each sheet should be more clear and definite;the methods for topographic correction and GPS altitude correction ought to be improved so as to raise the topographic correction precision;the interpretation level of the regional gravity survey result should be raised,and the report compilation should be further improved. |
