【摘要】：海上漂浮綠潮生物量的估算對實(shí)現(xiàn)綠潮處置資源高效配置、提高應(yīng)急處置效率具有重要意義。利用現(xiàn)場實(shí)驗(yàn)獲取的漂浮綠潮單位面積生物量及其地物反射光譜數(shù)據(jù),分析了漂浮綠潮光譜特征和多種光譜指數(shù)與單位面積生物量之間的響應(yīng)關(guān)系,基于此構(gòu)建并驗(yàn)證了漂浮綠潮生物量估算模型。結(jié)果顯示漂浮綠潮近紅外波段反射率與單位面積生物量之間存在強(qiáng)相關(guān)關(guān)系(相關(guān)系數(shù)R≈0.8);光譜指數(shù)以及960nm反射峰和1060nm吸收峰峰值與漂浮綠潮單位面積生物量顯著相關(guān)(R0.7);基于R_(960)/R_(670)和R_(1060)/R_(670)(R_(670),R_(960),R_(1060)分別為670,960,1060nm處的反射率)構(gòu)建的漂浮綠潮生物量指數(shù)估算模型具有較高的精度(R~2≈0.9,相對誤差R_(PE)≈27%)。研究結(jié)果為利用遙感技術(shù)實(shí)現(xiàn)海面漂浮綠潮生物量估算提供了參考。
[Abstract]:The estimation of floating green tide biomass on the sea is of great significance to realize the efficient allocation of green tide resources and improve the efficiency of emergency disposal. The spectral characteristics of floating green tide and the response relationship between various spectral indices and biomass per unit area were analyzed by using the data of floatation green tide unit area biomass and its reflection spectrum obtained from field experiments. Based on this, a model for estimating the biomass of floating green tide was constructed and verified. The results show that there is a strong correlation between reflectivity and biomass per unit area in near infrared band of floating green tide (correlation coefficient R 鈮，
