碳封存工程泄漏超高CO_2浓度对植被影响的多光谱遥感监测应用

Monitoring and Application of Multispectral Remote Sensing at the Vegetation Influence by the High CO_2 Concentration Leakage from Carbon Sequestration Project

利用天然CO_2气田模拟碳封存工程泄漏超高浓度CO_2后对生态环境影响研究基地,借助多光谱高分辨率遥感技术,在获取多个时相的卫星影像基础上,监测当地植被指数及变化趋势。结果表明:多光谱遥感技术能很好的应用于因高浓度CO_2泄漏造成的植被影响监测,既适用于微小尺度的精细监测,同时也对宏观范围内植被监测起到很好的效果,为完善我国二氧化碳地质封存工程环境影响监测技术方法体系提供科学支撑。

The research base of using natural CO_2 gas which simulated the high concentration of CO_2 leakage from carbon sequestration project was used to influence on the ecological environment. Based on different years of multiple phase satellite images,multispectral high resolution remote sensing technology was used to monitor local vegetation index and the change trends. The results showed that the multispectral remote sensing technique can be suitable for monitoring vegetation influenced by high concentrations of CO_2 leakage. The method could be applied for small scale monitoring,also have good effect to the macro scope vegetation monitoring,which provide scientific support for consummate CO_2 geological sequestration project of environmental impact monitoring technique method system in China.
