【摘要】：我國霧霾的發(fā)生時(shí)間成常年化趨勢,且在幾十年內(nèi)都可能存在,霧霾對地物光譜曲線測量的影響是不可避免的,而反射率光譜是眾多遙感參數(shù)反演的基礎(chǔ),因此定量分析霧霾對典型地物光譜曲線測量的影響是丞需解決的問題。本文以簡易的霧霾模擬實(shí)驗(yàn)室為基礎(chǔ),實(shí)際測量了不同霧霾濃度(晴空,濃度分別為35,75,150)下植被、土壤和水泥地的反射率光譜,同時(shí)與室外太陽光照下同一樣本進(jìn)行了對比測量和分析。本文首次綜合分析不同霧霾濃度對植被、土壤、水泥地等典型地物反射率光譜曲線測量的影響,對定量分析霧霾對遙感監(jiān)測、應(yīng)用的影響具有重要意義。主要的研究結(jié)論有:草坪、土壤、水泥地等主要地物測量的反射率光譜曲線在晴空時(shí)反射率值最高,反射率光譜曲線也最平滑,隨霧霾顆粒物濃度的增加,各主要地物的反射率都呈降低趨勢,但降幅都不盡相同,降幅沒有明顯的規(guī)律可循;霧霾對各主要地物測量的反射率的影響,在不同波段、不同含水量狀況都不盡相同,因此利用統(tǒng)計(jì)規(guī)律消除霧霾影響有較大困難。霧霾對地物測量的光譜的影響仍需進(jìn)一步深入研究。
[Abstract]:The occurrence time of smog in China is a perennial trend, and it may exist in several decades. The influence of smog on the spectral curve measurement of ground objects is inevitable, and reflectivity spectrum is the basis of the inversion of many remote sensing parameters. Therefore, quantitative analysis of the influence of smog on the spectral curve measurement of typical ground objects is a problem to be solved. Based on the simple smog simulation laboratory, the reflectance spectra of vegetation, soil and cement land were measured under different smog concentrations (clear sky, concentration of 35,75150). At the same time, the measurement and analysis of the same sample under outdoor sunlight were carried out. In this paper, the influence of different concentration of smog on spectral curve measurement of reflectance of typical ground objects such as vegetation, soil and cement is analyzed for the first time, which is of great significance for quantitative analysis of the influence of haze on remote sensing monitoring and application. The main conclusions are as follows: the reflectance spectral curves measured by lawn, soil, cement and other main objects are the highest in clear sky, and the reflectivity spectral curve is the smoothest, with the increase of the concentration of haze particles. The reflectivity of each major feature showed a decreasing trend, but the decrease was different and there was no obvious regularity to follow. The influence of smog on the reflectivity of each major ground object was different in different bands, and the water content was different in different bands. Therefore, it is difficult to eliminate the influence of smog by statistical law. The influence of smog on the spectral measurement of ground objects still needs further study.
