摘要
阐述了卫星遥感技术在环境保护中的应用现状,针对新乡市环境保护的具体需求,运用遥感图谱解译技术解决大面积地面固体污染源监测问题,利用大气气溶胶反演技术实现区域PM10空间态势分析。结合地面观测站实测数据,提出利用线性拟合与回归分析方法定量评价卫星遥感数据在环境保护应用的可行性,结果表明卫星遥感数据与地面站实测数据呈现高度相关性。与地面观测站以及人工现场监测相比,卫星遥感技术具有大范围、省时省力等优点,具有广阔的应用前景。但是由于大气气溶胶多变的时空特性、探测技术精度的限制及地域关键信息的缺失,气溶胶定量反演技术并不完善,需要开展进一步的研究。
In this paper,we described the application status of satellite remote sensing technology in environmental protection.According to the specific needs of environmental protection in Xinxiang City,we used the remote sensing map interpretation technology to solve the monitoring problem of large-scale surface solid pollution sources,and introduced the atmospheric aerosol inversion technology to realize the spatial situation analysis of regional PM10 index.Combining with the measured data of the ground station,we used the linear fitting and regression analysis method toquantitatively evaluate the feasibility of the application of the satellite remote sensing data in environmental protection.The results show that the satellite remote sensing data and the measured data of the ground station are highly correlated.Satellite remote sensing technology has the advantages of large-scale,time-saving and labor-saving,and has a broad application prospect.However,the aerosol quantitative inversion technology is not perfect and needs further research.
