南部非洲地学信息服务网的设计与实现

Design and implementation of Southern Africa Geoscience Information Service Network

开展境外矿产资源的勘查与开发利用是经济全球化形势下参与全球资源配置的重要举措。南部非洲地区具有丰富的矿产资源禀赋,是“一带一路”沿线的重要节点。为支撑服务中资矿业企业在南部非洲地区开展矿产资源勘查开发活动,研发并上线了南部非洲地学信息服务网,实现了南部非洲矿业投资环境和基础地学数据的集成与共享。该服务网兼顾实用性与扩展性,从功能实现的角度进行开发,采用SOA面向服务构架,基于WebService技术构建了分布式地理信息共享与应用开发环境,运用python信息自动爬虫技术和多源异构数据集成技术,开发了浏览和查询、投资环境一张图、投资环境评价、借阅服务、运维管理等五个模块,集成了南部非洲地区自然地理、基础设施建设、社会文化与教育、政治环境与安全、矿业经济及主要矿产资源潜力等信息,实现了空间数据与非结构化数据的共享、发布与浏览,可为南部非洲25个国家矿业投资提供一站式信息服务,精准支撑中资矿业企业“走出去”与投资合作。

Under the background of economic globalization,carrying out the exploitation and utilization of overseas mineral resources is a significant measure to participate in the global resource allocation.Southern Africa,rich in mineral resources,is an important node along the Belt and Road.In order to provide accurate services related to the exploitation and utilization of mineral resources in Southern Africa for Chinese enterprises and institutions,the Southern Africa Geoscience Information Service Network,which achieved the integration and sharing of the Southern African mining investment environment and basic geoscience data,is developed and launched.The service network takes into account the practicality and scalability,develops from the perspective of functional realization,adopts SOA service-oriented architecture,builds a distributed geographic information sharing and application development environment based on WebService technology,uses python information automatic crawler technology and multi-source heterogeneous data integration technology,develops five modules,including browsing and query,investment environment map,investment environment assessment,lending service and operation management.It integrates information on physical geography,infrastructure construction,social culture and education,political environment and security,mining industry economics and mineral resources potential in Southern Africa,and implements sharing,publishing and browsing of spatial data and unstructured data.It can provide one-stop information services for mining investment of 25 countries in Southern Africa,and thereby accurately support“Going-Out”for Chinese mining companies and investment cooperation.
