地震遥感应用趋势与中国地震卫星发展框架

Remote Sensing Application in Earthquake Science and General Proposal for Earthquake Satellite Project in China

在赵九章先生的倡议下,我国的人造地球卫星事业经过50年的历程,已经取得了长足的发展,卫星遥感应用范围也日益扩大。在防震减灾领域,卫星遥感也在监测预报、灾害评估和地震构造研究等许多方面得到应用并显示了巨大的发展前景,从而对发展地震卫星系统提出了现实的要求。我国地震卫星系统发展的总体思路是:基于社会公共安全事业发展和防震减灾能力建设的需要,结合国家民用遥感卫星统筹发展,优先开展地震电磁卫星的论证和研发,积极参与InSAR、重力等其他民用遥感卫星的论证;逐步建立多源遥感信息快速稳定的获取渠道和专业化处理平台,促进立体地震观测体系建设。目前,中国地震电磁试验卫星综合论证工作正在顺利进行,试验卫星的科学目标、载荷配置方案以及对卫星平台和运行能力的要求已经初步明确,将按计划推动背景型号和工程型号项目,并同步开展若干关键技术的国内外合作研究。

Development of satellite and space science in China has under the p passed through for 50 years from the late academician Zhao Jiuzhang, the technique and application in this field are widely developed up to now. The satellite-based remote sensing is being used in earthquake monitoring, hazard evaluating and seismo-tectonics research for earthquake hazard prevention and mitigation. According to the opinion about the foreground of remote sensing application in earth-quake science, the proposal for special seismo-satellite system in China has been put forward. The general ideas for China＇s seismo-satellite system are as follows： to demonstrate and develop seismo-electromagnetism satellite as the priority in the project and to take part in the＇demonstration of InSAR and gravity satellite at the same time according to the plan of civil satellites as a whole, based on the demands of public safety as well as earthquake hazards prevention and mitigation; to construct multipie-sensors, multiple-parameters, quasi-real time and steady-going platform for data acquiring and processing, and to promote the 3D earthquake monitoring system step by step. Now the integrative demonstration for the first China＇s seismo-electromagnetism trial satellite is going on smoothly, and the scientific objects, payloads as well as the demands for platform and operation are proposed, it is trusted that this project will carry out under the plan.
