试论省（区）国土资源地图集的编制原则     

詹启仁 《地域研究与开发》1990,9(1):42-46

编制省(区)国土资源地图集和编制其它地图集一样,是一项复杂的系统工程,由总体设计系统、编辑试验系统、编绘实施系统、制印生产系统组成,这些阶段或分系统都是密切相关、相互影响的。要完成这样复杂的系统工程,需要科学的理论指导,使用先进的技术方法和合理有效的组织领导。其中最根本的是用统一的设计思想,进行系统的分析和设计,通过总体设计系统把复杂的各种工序变为众多参加者的具体作业,把各种具体作业纳入总体设计思想,以便完成一部高质量的地图集。因此总体设计是编制地图集的基础工作,而明确图集的编制原则又是图集总体设计的重要组成部分。下面结合甘肃省国土资源地图集的编制实  相似文献

Geochemical survey of thermal system in Northeast China and their geothermometric characters     

MohammedHazaea HUKe MohammedMattash CHENBing M.O.AI-JabaliAref MohammedAbdussalam 《东北亚地学研究》2004,7(2):181-184

The chemical composition of several thermal springs around Changbaishan area has been investigated. Cenozoic basaltic rocks are widely distributed in Northeast China and geothermal characteristics have been described. About one hundred hot springs exist around Changhaishan Volcano at the border between China and D.P.R.Korea with high temperature about 82~C. The pH values of the spring water range from 6.9 to 7.1 and the total flow rate is about 4.8 L/sec. The chemical composition of the thermal springs is sodium carbonate; the high-mineral contents of thermal water are believed to have medicinal properties. Bathhouses are already built along the hot springs to take the advantage of the supposed healing properties. The high quality of those hot springs is believed to be utilitized for mineral water. The chemical equilibrium temperatures were estimated at about 160℃ based on the Na-K-Ca geochemical thermometer.  相似文献
