【摘要】 以高空间分辨率的Quickbird卫星图像和高光谱分辨率的OMISⅠ航空高光谱图像数据为信息源,结合细分光谱仪、红外测温计等地面遥感技术,对宁夏汝箕沟煤田的煤火现状进行了定量调查分析及动态监测,查明了煤田煤火的范围、强度,分析了不同时期煤田火区的变化规律,评价了火区治理效果并对后续灭火工作提出建议,为火区治理提供了决策依据。更多还原

【Abstract】 To take the high spatial resolution Quickbird satellite imagery and high spectral resolution OMIS 1 aerial spectrogram as information sources,integrated with ground surface remote sensing techniques of fractionized spectrometer and infrared thermodetector,the authors carried out quantitative surveying analysis and dynamic monitoring for coalfield fire in Rujigou coalfield,Ningxia have made certain of coalfield fire limits and intensity,analyzed fire area changing pattern during different stages,assessed fire harnessing effect and put forward suggestions for subsequent fire-fighting tasks.Thus they provided strategic decision basis for put coalfield fire areas in order.更多还原
